Description: T-CELL RECEPTOR BETA-LIKE PROTEIN TECHNICAL FIELD This invention relates to nucleic acid and amino acid sequences of a T-cell receptor beta- like protein and to the use of these sequences in the diagnosis, prevention, and treatment of cancer and autoimmune disorders. BACKGROUND OF THE INVENTION T cells play a central role in the immune system as effectors and regulators, coupling antigen recognition and the transmission of activation signals. The diverse responses of T cells are referred to as cell-mediated immune reactions and are initiated by recognition of antigens via the T cell receptor (TCR). T cells recognize a wide range of different antigens. As with B cells, a particular clonal line of T cells can only recognize a single antigen. However, unlike B cells, T cells recognize antigens only when they are presented to the TCR as peptides in a complex with major histocompatibility molecules (MHC) on the surface of antigen presenting cells. The TCR on most T cells consist of immunoglobulin-like integral membrane glycoproteins containing 2 polypeptide subunits, alpha and beta, of similar molecular weight. Each T-cell receptor subunit has an external amino terminal containing both a variable (V) domain and a constant (C)domain. The genes for the T-cell receptor subunits are constructed through somatic rearrangement of different gene segments, of which there are at least 3 types for the alpha; V, joining (J) and C domains, and at least types 4 for the beta; V, diversity (D), J and C domains. An invariant CD3 complex of polypeptides and a disulfide-linked homodimer are noncovalently associated with the TCR. These associated polypeptides are responsible for the signal transduction functions ofthe TCR and are also required for efficient surface expression ofthe intact receptor. Interaction of antigen in the proper MHC context with the TCR leads to a regulated series of events resulting in differentiation, proliferation, and the acquisition of T cell immunologic function. The particular functional response depends on whether the T cell receives co- stimulatory signals through other surface receptors and which signal transduction pathways are activated (Klausner, R. D. and Samelson, L., E. (1991) Cell 64: 875-878; Clevers, H. et al. (1988) Annu. Rev. Immunol. 6: 629-662). The signaling cascades initiated by TCR activation include the inositol tri- phosphate/Ca2 + , diacylglycerol/protein kinase C, Ras/mitogen-activated protein kinase, and the PI 3-K pathways. Components of these pathways transmit information into the nucleus to activate the genes that code for a variety of secreted factors such as IL-2, IL-4, IL-7, IL-9, IL-10, and interferon-γ, which subsequently induce the proliferation, maturation, and function of cellular components ofthe immune system. These factors can stimulate the induction of antibody secretion and class switching in B cells, the regulation of humoral immunity, and induction of tumorocidal and anti-inflammatory activity (Alderson, M., R., et al (1991) J. Exp. Med. 173: 923-930; and Weiss, A. (1991) Annu. Rev. Genet. 25: 487-510). The TCR antigen repertoire is established by developmentally regulated TCR gene rearrangements and is shaped by intrathymic selection processes. Immature T cells undergo a selection and differentiation process based on antigen binding prior to leaving the thyrnus. Those that bind self-antigens while still in the cortex ofthe thyrnus are eliminated by apoptosis, establishing immunological tolerance. Failure to eliminate self reactive populations of cells has been shown to result in autoimmune disease. Immature T cells express both CD4 and CD8 co- receptors which assist in MHC recognition; thymic maturation produces T cells expressing one or the other of these receptors. This maturation process is dependent on the structure ofthe surface TCR complexes expressed. Results of animal studies indicate that the successful differentiation into single-positive (bearing either CD4 or CD8) T cells requires surface expression of fully assembled TCR complexes (Shores, E. W., et al. (1993) J Immunol 150 4: 1263-1275 and Olive, C. (1995) Immunol. Cell Biol. 73: 297-307). Defects in TCR genes, TCR expression, and T cell subtype population levels have been noted in lymphomas, leukemias, allergic responses, and autoimmune and immunodeficiency disorders. In transgenic mice deficient in the TCR alpha and beta subunits, B cells expand, differentiate and secrete copious amounts of antibodies that are reactive towards self antigens. Graft-versus-host disease is the result of normal T cell responses to cells perceived as foreign, as is the cytolitic destruction of virus infected and rumor cells. As more human TCR subunit genes are identified, additional specific functions ofthe TCR can be characterized (Yui, K. et al (1992) Eur J Immunol 22: 1693-1700; Olive, C, supra (1995); Mombaerts, P., et al (1993) Cell 75: 274-282; Wen, L., et al (1994) Nature 369 :654-658: Leiden, J., M., et al. (1986) Immunogenet. 24: 17-23: and Barber, D., F., and Lopez de Castro, J., A., Genbank accession L34734) The discovery of a new T-cell receptor beta-like protein and the polynucleotides encoding it satisfies a need in the art by providing new compositions which are useful in the diagnosis, prevention and treatment of cancer and autoimmune disorders. SUMMARY OF THE INVENTION The invention features a substantially purified polypeptide, T-cell receptor beta-like protein (TCRLP), having the amino acid sequence shown in SEQ ID NO: 1, or fragments thereof.

DESCRIPTION OF THE INVENTION Before the present proteins, nucleotide sequences, and methods are described, it is understood that this invention is not limited to the particular methodology, protocols, cell lines, vectors, and reagents described, as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope ofthe present mvention which will be limited only by the appended claims. It must be noted that as used herein and in the appended claims, the singular forms "a", "an", and "the" include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to "a host cell" includes a plurality of such host cells, reference to the "antibody" is a reference to one or more antibodies and equivalents thereof known to those skilled in the art, and so forth. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing ofthe present invention, the preferred methods, devices, and materials are now described. All publications mentioned herein are incorporated herein by reference for the purpose of describing and disclosing the cell lines, vectors, and methodologies which are reported in the publications which might be used in connection with the invention. Nothing herein is to be construed as an admission that the invention is not entitled to antedate such disclosure by virtue of prior invention. DEFINITIONS T-cell receptor beta-like protein, as used herein, refers to the amino acid sequences of substantially purified T-cell receptor beta-like protein obtained from any species, particularly mammalian, including bovine, ovine, porcine, murine, equine, and preferably human, from any source whether natural, synthetic, semi-synthetic, or recombinant. The term "agonist", as used herein, refers to a molecule which, when bound to T-cell receptor beta-like protein, increases or prolongs the duration ofthe effect of T-cell receptor betalike protein. Agonists may include proteins, nucleic acids, carbohydrates, or any other molecules which bind to and modulate the effect of T-cell receptor beta-like protein. An "allele" or "allelic sequence", as used herein, is an alternative form ofthe gene encoding T-cell receptor beta-like protein. Alleles may result from at least one mutation in the nucleic acid sequence and may result in altered mRNAs or polypeptides whose structure or function may or may not be altered. Any given natural or recombinant gene may have none, one, or many allelic forms. Common mutational changes which give rise to alleles are generally ascribed to natural deletions, additions, or substitutions of nucleotides. Each of these types of changes may occur alone, or in combination with the others, one or more times in a given sequence. "Altered" nucleic acid sequences encoding T-cell receptor beta-like protein as used herein include those with deletions, insertions, or substitutions of different nucleotides resulting in a polynucleotide that encodes the same or a functionally equivalent T-cell receptor beta-like protein. Included within this definition are polymorphisms which may or may not be readily detectable using a particular oligonucleotide probe ofthe polynucleotide encoding T-cell receptor beta-like protein, and improper or unexpected hybridization to alleles, with a locus other than the normal chromosomal locus for the polynucleotide sequence encoding T-cell receptor beta-like protein. The encoded protein may also be "altered" and contain deletions, insertions, or substitutions of amino acid residues which produce a silent change and result in a functionally equivalent T-cell receptor beta-like protein. Deliberate amino acid substitutions may be made on the basis of similarity in polarity, charge, solubility, hydrophobicity, hydrophilicity, and/or the amphipathic nature ofthe residues as long as the biological or immunological activity of T-cell receptor beta-like protein is retained. For example, negatively charged amino acids may include aspartic acid and glutamic acid; positively charged amino acids may include lysine and arginine; and amino acids with uncharged polar head groups having similar hydrophilicity values may include leucine, isoleucine, and valine, glycine and alanine, asparagine and glutamine, serine and threonine, and phenylalanine and tyrosine. "Amino acid sequence" as used herein refers to an oligopeptide, peptide, polypeptide, or protein sequence, and fragment thereof, and to naturally occurring or synthetic molecules. Fragments of T-cell receptor beta-like protein are preferably about 5 to about 15 amino acids in length and retain the biological activity or the immunological activity of T-cell receptor beta-like protein. Where "amino acid sequence" is recited herein to refer to an amino acid sequence of a naturally occurring protein molecule, amino acid sequence, and like terms, are not meant to limit the amino acid sequence to the complete, native amino acid sequence associated with the recited protein molecule. "Amplification" as used herein refers to the production of additional copies of a nucleic acid sequence and is generally carried out using polymerase chain reaction (PCR) technologies well known in the art (Dieffenbach, C.W. and G.S. Dveksler (1995) PCR Primer, a Laboratory Manual Cold Spring Harbor Press, Plainview, NY). The term "antagonist" as used herein, refers to a molecule which, when bound to T-cell receptor beta-like protein, decreases the amount or the duration of the effect ofthe biological or immunological activity of T-cell receptor beta-like protein. Antagonists may include proteins, nucleic acids, carbohydrates, antibodies or any other molecules which decrease the effect of T- cell receptor beta-like protein. As used herein, the term "antibody" refers to intact molecules as well as fragments thereof, such as Fa, F(ab') 2 , and Fv, which are capable of binding the epitopic determinant. Antibodies that bind T-cell receptor beta-like protein polypeptides can be prepared using intact polypeptides or fragments containing small peptides of interest as the immunizing antigen. The polypeptide or oligopeptide used to immunize an animal can be derived from the translation of RNA or synthesized chemically and can be conjugated to a carrier protein, if desired. Commonly used carriers that are chemically coupled to peptides include bovine serum albumin and thyroglobulin, keyhole limpet hemocyanin. The coupled peptide is then used to immunize the animal (e.g., a mouse, a rat, or a rabbit). The term "antigenic determinant", as used herein, refers to that fragment of a molecule (i.e., an epitope) that makes contact with a particular antibody. When a protein or fragment of a protein is used to immunize a host animal, numerous regions of the protein may induce the production of antibodies which bind specifically to a given region or three-dimensional structure on the protein; these regions or structures are referred to as antigenic determinants. An antigenic determinant may compete with the intact antigen (i.e., the immunogen used to elicit the immune response) for binding to an antibody. The term "antisense", as used herein, refers to any composition containing nucleotide sequences which are complementary to a specific DNA or RNA sequence. The term "antisense strand" is used in reference to a nucleic acid strand that is complementary to the "sense" strand. Antisense molecules include peptide nucleic acids and may be produced by any method including synthesis or transcription. Once introduced into a cell, the complementary nucleotides combine with natural sequences produced by the cell to form duplexes and block either transcription or translation. The designation "negative" is sometimes used in reference to the antisense strand, and "positive" is sometimes used in reference to the sense strand. The term "biologically active", as used herein, refers to a protein having structural, regulatory, or biochemical functions of a naturally occurring molecule. Likewise, "immunologically active" refers to the capability of the natural, recombinant, or synthetic T-cell receptor beta-like protein, or any oligopeptide thereof, to induce a specific immune response in appropriate animals or cells and to bind with specific antibodies. The terms "complementary" or "complementarity", as used herein, refer to the natural binding of polynucleotides under permissive salt and temperature conditions by base-pairing. For example, the sequence "A-G-T" binds to the complementary sequence "T-C-A". Complementarity between two single-stranded molecules may be "partial", in which only some ofthe nucleic acids bind, or it may be complete when total complementarity exists between the single stranded molecules. The degree of complementarity between nucleic acid strands has significant effects on the efficiency and strength of hybridization between nucleic acid strands. This is of particular importance in amplification reactions, which depend upon binding between nucleic acids strands and in the design and use of PNA molecules. A "composition comprising a given polynucleotide sequence" as used herein refers broadly to any composition containing the given polynucleotide sequence. The composition may comprise a dry formulation or an aqueous solution. Compositions comprising polynucleotide sequences encoding T-cell receptor beta-like protein (SEQ ID NO: 1) or fragments thereof (e.g., SEQ ID NO: 2 and fragments thereof) may be employed as hybridization probes. The probes may be stored in freeze-dried form and may be associated with a stabilizing agent such as a carbohydrate. In hybridizations, the probe may be deployed in an aqueous solution containing salts (e.g., NaCl), detergents (e.g., SDS) and other components (e.g., Denhardt's solution, dry milk, salmon sperm DNA, etc.). "Consensus", as used herein, refers to a nucleic acid sequence which has been resequenced to resolve uncalled bases, has been extended using XL-PCR™ (Perkin Elmer, Norwalk, CT) in the 5' and/or the 3' direction and resequenced, or has been assembled from the overlapping sequences of more than one Incyte Clone using a computer program for fragment assembly (e.g., GELVIEW™ Fragment Assembly system, GCG, Madison, WI). Some sequences have been both extended and assembled to produce the consensus sequence . The term "correlates with expression of a polynucleotide", as used herein, indicates that the detection ofthe presence of ribonucleic acid that is similar to SEQ ID NO:2 by northern analysis is indicative ofthe presence of mRNA encoding T-cell receptor beta-like protein in a sample and thereby correlates with expression ofthe transcript from the polynucleotide encoding the protein. A "deletion", as used herein, refers to a change in the amino acid or nucleotide sequence and results in the absence of one or more amino acid residues or nucleotides. The term "derivative", as used herein, refers to the chemical modification of a nucleic acid encoding or complementary to T-cell receptor beta-like protein or the encoded T-cell receptor beta-like protein. Such modifications include, for example, replacement of hydrogen by an alkyl, acyl, or amino group. A nucleic acid derivative encodes a polypeptide which retains the biological or immunological function of the natural molecule. A derivative polypeptide is one which is modified by glycosylation, pegylation, or any similar process which retains the biological or immunological function ofthe polypeptide from which it was derived. The term "homology", as used herein, refers to a degree of complementarity. There may be partial homology or complete homology (i.e., identity). A partially complementary sequence that at least partially inhibits an identical sequence from hybridizing to a target nucleic acid is referred to using the functional term "substantially homologous." The inhibition of hybridization ofthe completely complementary sequence to the target sequence may be examined using a hybridization assay (Southern or northern blot, solution hybridization and the like) under conditions of low stringency. A substantially homologous sequence or hybridization probe will compete for and inhibit the binding of a completely homologous sequence to the target sequence under conditions of low stringency. This is not to say that conditions of low stringency are such that non-specific binding is permitted; low stringency conditions require that the binding of two sequences to one another be a specific (i.e., selective) interaction. The absence of non-specific binding may be tested by the use of a second target sequence which lacks even a partial degree of complementarity (e.g., less than about 30% identity). In the absence of non-specific binding, the probe will not hybridize to the second non-complementary target sequence. Human artificial chromosomes (HACs) are linear microchromosomes which may contain DNA sequences of 10K to 10M in size and contain all ofthe elements required for stable mitotic chromosome segregation and maintenance (Harrington, J.J. et al. (1997) Nat Genet. 15:345-355). The term "humanized antibody", as used herein, refers to antibody molecules in which amino acids have been replaced in the non-antigen binding regions in order to more closely resemble a human antibody, while still retaining the original binding ability. The term "hybridization", as used herein, refers to any process by which a strand of nucleic acid binds with a complementary strand through base pairing. The term "hybridization complex", as used herein, refers to a complex formed between two nucleic acid sequences by virtue ofthe formation of hydrogen bonds between complementary G and C bases and between complementary A and T bases; these hydrogen bonds may be further stabilized by base stacking interactions. The two complementary nucleic acid sequences hydrogen bond in an antiparallel configuration. A hybridization complex may be formed in solution (e.g., C 0 t or Rot analysis) or between one nucleic acid sequence present in solution and another nucleic acid sequence immobilized on a solid support (e.g., paper, membranes, filters, chips, pins or glass slides, or any other appropriate substrate to which cells or their nucleic acids have been fixed). An "insertion" or "addition", as used herein, refers to a change in an amino acid or nucleotide sequence resulting in the addition of one or more amino acid residues or nucleotides, respectively, as compared to the naturally occurring molecule. "Microarray" refers to an array of distinct polynucleotides or oligonucleotides synthesized on a substrate, such as paper, nylon or other type of membrane, filter, chip, glass slide, or any other suitable solid support. The term "modulate", as used herein, refers to a change in the activity of T-cell receptor beta-like protein. For example, modulation may cause an increase or a decrease in protein activity, binding characteristics, or any other biological, functional or immunological properties of T-cell receptor beta-like protein. "Nucleic acid sequence" as used herein refers to an oligonucleotide, nucleotide, or polynucleotide, and fragments thereof, and to DNA or RNA of genomic or synthetic origin which may be single- or double-stranded, and represent the sense or antisense strand. "Fragments" are those nucleic acid sequences which are greater than 60 nucleotides than in length, and most preferably includes fragments that are at least 100 nucleotides or at least 1000 nucleotides, and at least 10,000 nucleotides in length. The term "oligonucleotide" refers to a nucleic acid sequence of at least about 6 nucleotides to about 60 nucleotides, preferably about 15 to 30 nucleotides, and more preferably about 20 to 25 nucleotides, which can be used in PCR amplification or a hybridization assay, or a microarray. As used herein, oligonucleotide is substantially equivalent to the terms "amplimers", "primers", "oligomers", and "probes", as commonly defined in the art. "Peptide nucleic acid", PNA as used herein, refers to an antisense molecule or anti-gene agent which comprises an oligonucleotide of at least five nucleotides in length linked to a peptide backbone of amino acid residues which ends in lysine. The terminal lysine confers solubility to the composition. PNAs may be pegylated to extend their lifespan in the cell where they preferentially bind complementary single stranded DNA and RNA and stop transcript elongation (Nielsen, P.E. et al. (1993) Anticancer Drug Des. 8:53-63). The term "portion", as used herein, with regard to a protein (as in "a portion of a given protein") refers to fragments of that protein. The fragments may range in size from five amino acid residues to the entire amino acid sequence minus one amino acid. Thus, a protein "comprising at least a portion ofthe amino acid sequence of SEQ ID NO: l" encompasses the full-length T-cell receptor beta-like protein and fragments thereof. The term "sample", as used herein, is used in its broadest sense. A biological sample suspected of containing nucleic acid encoding T-cell receptor beta-like protein, or fragments thereof, or T-cell receptor beta-like protein itself may comprise a bodily fluid, extract from a cell, chromosome, organelle, or membrane isolated from a cell, a cell, genomic DNA, RNA, or cDNA(in solution or bound to a solid support, a tissue, a tissue print, and the like. The terms "specific binding" or "specifically binding", as used herein, refers to that interaction between a protein or peptide and an agonist, an antibody and an antagonist. The interaction is dependent upon the presence of a particular structure (i.e., the antigenic determinant or epitope) of the protein recognized by the binding molecule. For example, if an antibody is specific for epitope "A", the presence of a protein containing epitope A (or free, unlabeled A) in a reaction containing labeled "A" and the antibody will reduce the amount of labeled A bound to the antibody. The terms "stringent conditions'Or "stringency", as used herein, refer to the conditions for hybridization as defined by the nucleic acid, salt, and temperature. These conditions are well known in the art and may be altered in order to identify or detect identical or related polynucleotide sequences. Numerous equivalent conditions comprising either low or high stringency depend on factors such as the length and nature of the sequence (DNA, RNA, base composition), nature ofthe target (DNA, RNA, base composition), milieu (in solution or immobilized on a solid substrate), concentration of salts and other components (e.g., formamide, dextran sulfate and/or polyethylene glycol), and temperature ofthe reactions (within a range from about 5°C below the melting temperature ofthe probe to about 20°C to 25°C below the melting temperature). One or more factors be may be varied to generate conditions of either low or high stringency different from, but equivalent to, the above listed conditions. The term "substantially purified", as used herein, refers to nucleic or amino acid sequences that are removed from their natural environment, isolated or separated, and are at least 60% free, preferably 75%) free, and most preferably 90%> free from other components with which they are naturally associated. A "substitution", as used herein, refers to the replacement of one or more amino acids or nucleotides by different amino acids or nucleotides, respectively. "Transformation", as defined herein, describes a process by which exogenous DNA enters and changes a recipient cell. It may occur under natural or artificial conditions using various methods well known in the art. Transformation may rely on any known method for the insertion of foreign nucleic acid sequences into a prokaryotic or eukaryotic host cell. The method is selected based on the type of host cell being transformed and may include, but is not limited to, viral infection, electroporation, heat shock, lipofection, and particle bombardment. Such "transformed" cells include stably transformed cells in which the inserted DNA is capable of replication either as an autonomously replicating plasmid or as part ofthe host chromosome. They also include cells which transiently express the inserted DNA or RNA for limited periods of time. A "variant" of TCRLP, as used herein, refers to an amino acid sequence that is altered by one or more amino acids. The variant may have "conservative" changes, wherein a substituted amino acid has similar structural or chemical properties, e.g., replacement of leucine with isoleucine. More rarely, a variant may have "nonconservative" changes, e.g., replacement of a glycine with a tryptophan. Analogous minor variations may also include amino acid deletions or insertions, or both. Guidance in determining which amino acid residues may be substituted, inserted, or deleted without abolishing biological or immunological activity may be found using computer programs well known in the art, for example, DNASTAR software. THE INVENTION The invention is based on the discovery of a new human T-cell receptor beta-like protein (hereinafter referred to as "TCRLP"), the polynucleotides encoding TCRLP, and the use of these compositions for the diagnosis, prevention, or treatment of cancer and autoimmune disorders. Nucleic acids encoding the TCRLP ofthe present invention were first identified in Incyte Clone 983910 from the tongue tumor cDNA library (TONGTUT01) using a computer search for amino acid sequence alignments. A consensus sequence, SEQ ID NO:2, was derived from the following overlapping and/or extended nucleic acid sequences: Incyte Clones 983910 (TONGTUT01), 343545 (THYMNOT02), 1282195 (COLNNOT16), 1876350 (LEUKNOT02), 1603501 (LUNGNOT15). In one embodiment, the invention encompasses a polypeptide comprising the amino acid sequence of SEQ ID NO: l, as shown in Figs. 1A, IB, IC, and ID. TCRLP is 314 amino acids in length and has one potential N-glycosylation site at N 205 , four potential caseine kinase π phosphorylation sites at S 120 , T 133 , S, 52 , and S 239 , and five potential protein kinase C phosphorylation sites, at S 28 , T 32 , T 95 , T 159 , and S 212 . As shown in Figs. 2A and 2B, TCRLP has chemical and structural homology with human T-cell receptor beta (GI 1100182; SEQ ID NO:3) and human T-cell receptor precursor (GI 339012; SEQ ID NO:4). In particular, TCRLP and human T-cell receptor beta (GI 1 100182) share 85%> identity and TCRLP and human T-cell receptor precursor (GI 339012) share 82%> identity. Northern analysis shows the expression of this sequence in various libraries, most of which are which are fetal and immune cell libraries. The invention also encompasses TCRLP variants. A preferred TCRLP variant is one having at least 80%, and more preferably at least 90%>, amino acid sequence identity to the TCRLP amino acid sequence (SEQ ID NO:l) and which retains at least one biological, immunological or other functional characteristic or activity of TCRLP. A most preferred TCRLP variant is one having at least 95%> amino acid sequence identity to SEQ ID NO:l. The invention also encompasses polynucleotides which encode TCRLP. Accordingly, any nucleic acid sequence which encodes the amino acid sequence of TCRLP can be used to produce recombinant molecules which express TCRLP. In a particular embodiment, the invention encompasses the polynucleotide comprising the nucleic acid sequence of SEQ ID NO:2 as shown in Fig. 1. It will be appreciated by those skilled in the art that as a result ofthe degeneracy ofthe genetic code, a multitude of nucleotide sequences encoding TCRLP, some bearing minimal homology to the nucleotide sequences of any known and naturally occurring gene, may be produced. Thus, the invention contemplates each and every possible variation of nucleotide sequence that could be made by selecting combinations based on possible codon choices. These combinations are made in accordance with the standard triplet genetic code as applied to the nucleotide sequence of naturally occurring TCRLP, and all such variations are to be considered as being specifically disclosed. Although nucleotide sequences which encode TCRLP and its variants are preferably capable of hybridizing to the nucleotide sequence of the naturally occurring TCRLP under appropriately selected conditions of stringency, it may be advantageous to produce nucleotide sequences encoding TCRLP or its derivatives possessing a substantially different codon usage. Codons may be selected to increase the rate at which expression of the peptide occurs in a particular prokaryotic or eukaryotic host in accordance with the frequency with which particular codons are utilized by the host. Other reasons for substantially altering the nucleotide sequence encoding TCRLP and its derivatives without altering the encoded amino acid sequences include the production of RNA transcripts having more desirable properties, such as a greater half-life, than transcripts produced from the naturally occurring sequence. The invention also encompasses production of DNA sequences, or fragments thereof, which encode TCRLP and its derivatives, entirely by synthetic chemistry. After production, the synthetic sequence may be inserted into any ofthe many available expression vectors and cell systems using reagents that are well known in the art. Moreover, synthetic chemistry may be used to introduce mutations into a sequence encoding TCRLP or any fragment thereof. Also encompassed by the invention are polynucleotide sequences that are capable of hybridizing to the claimed nucleotide sequences, and in particular, those shown in SEQ ID NO:2, under various conditions of stringency as taught in Wahl, G.M. and S.L. Berger (1987; Methods Enzymol. 152:399-407) and Kimmel, A.R. (1987; Methods Enzymol. 152:507-511). Methods for DNA sequencing which are well known and generally available in the art and may be used to practice any ofthe embodiments ofthe invention. The methods may employ such enzymes as the Klenow fragment of DNA polymerase I, Sequenase® (US Biochemical Corp, Cleveland, OH), Taq polymerase (Perkin Elmer), thermostable T7 polymerase (Amersham, Chicago, IL), or combinations of polymerases and proofreading exonucleases such as those found in the ELONGASE Amplification System marketed by Gibco/BRL (Gaithersburg, MD). Preferably, the process is automated with machines such as the Hamilton Micro Lab 2200 (Hamilton, Reno, NV), Peltier Thermal Cycler (PTC200; MJ Research, Watertown, MA) and the ABI Catalyst and 373 and 377 DNA Sequencers (Perkin Elmer). The nucleic acid sequences encoding TCRLP may be extended utilizing a partial nucleotide sequence and employing various methods known in the art to detect upstream sequences such as promoters and regulatory elements. For example, one method which may be employed, "restriction-site" PCR, uses universal primers to retrieve unknown sequence adjacent to a known locus (Sarkar, G. (1993) PCR Methods Applic. 2:318-322). In particular, genomic DNA is first amplified in the presence of primer to a linker sequence and a primer specific to the known region. The amplified sequences are then subjected to a second round of PCR with the same linker primer and another specific primer internal to the first one. Products of each round of PCR are transcribed with an appropriate RNA polymerase and sequenced using reverse transcriptase. Inverse PCR may also be used to amplify or extend sequences using divergent primers based on a known region (Triglia, T. et al. (1988) Nucleic Acids Res. 16:8186). The primers may be designed using commercially available software such as OLIGO 4.06 Primer Analysis software (National Biosciences Inc., Plymouth, MN), or another appropriate program, to be 22-30 nucleotides in length, to have a GC content of 50%> or more, and to anneal to the target sequence at temperatures about 68°-72° C. The method uses several restriction enzymes to generate a suitable fragment in the known region of a gene. The fragment is then circularized by intramolecular ligation and used as a PCR template. Another method which may be used is capture PCR which involves PCR amplification of DNA fragments adjacent to a known sequence in human and yeast artificial chromosome DNA (Lagerstrom, M. et al. (1991) PCR Methods Applic. 1 : 111-119). In this method, multiple restriction enzyme digestions and ligations may also be used to place an engineered double-stranded sequence into an unknown fragment of the DNA molecule before performing PCR. Another method which may be used to retrieve unknown sequences is that of Parker, J.D. et al. (1991; Nucleic Acids Res. 19:3055-3060). Additionally, one may use PCR, nested primers, and PromoterFinder™ libraries to walk genomic DNA (Clontech, Palo Alto, CA). This process avoids the need to screen libraries and is useful in finding intron/exon junctions. When screening for full-length cDNAs, it is preferable to use libraries that have been size-selected to include larger cDNAs. Also, random-primed libraries are preferable, in that they will contain more sequences which contain the 5' regions of genes. Use of a randomly primed library may be especially preferable for situations in which an oligo d(T) library does not yield a full-length cDNA. Genomic libraries may be useful for extension of sequence into 5' non-transcribed regulatory regions. Capillary electrophoresis systems which are commercially available may be used to analyze the size or confirm the nucleotide sequence of sequencing or PCR products. In particular, capillary sequencing may employ flowable polymers for electrophoretic separation, four different fluorescent dyes (one for each nucleotide) which are laser activated, and detection ofthe emitted wavelengths by a charge coupled devise camera. Output/light intensity may be converted to electrical signal using appropriate software (e.g. Genotyper™ and Sequence Navigator™, Perkin Elmer) and the entire process from loading of samples to computer analysis and electronic data display may be computer controlled. Capillary electrophoresis is especially preferable for the sequencing of small pieces of DNA which might be present in limited amounts in a particular sample. In another embodiment ofthe invention, polynucleotide sequences or fragments thereof which encode TCRLP may be used in recombinant DNA molecules to direct expression of TCRLP, fragments or functional equivalents thereof, in appropriate host cells. Due to the inherent degeneracy ofthe genetic code, other DNA sequences which encode substantially the same or a functionally equivalent amino acid sequence may be produced, and these sequences may be used to clone and express TCRLP. As will be understood by those of skill in the art, it may be advantageous to produce TCRLP-encoding nucleotide sequences possessing non-naturally occurring codons. For example, codons preferred by a particular prokaryotic or eukaryotic host can be selected to increase the rate of protein expression or to produce an RNA transcript having desirable properties, such as a half-life which is longer than that of a transcript generated from the naturally occurring sequence. The nucleotide sequences ofthe present invention can be engineered using methods generally known in the art in order to alter TCRLP encoding sequences for a variety of reasons, including but not limited to, alterations which modify the cloning, processing, and/or expression of the gene product. DNA shuffling by random fragmentation and PCR reassembly of gene fragments and synthetic oligonucleotides may be used to engineer the nucleotide sequences. For example, site-directed mutagenesis may be used to insert new restriction sites, alter glycosylation patterns, change codon preference, produce splice variants, introduce mutations, and so forth. In another embodiment ofthe invention, natural, modified, or recombinant nucleic acid sequences encoding TCRLP may be ligated to a heterologous sequence to encode a fusion protein. For example, to screen peptide libraries for inhibitors of TCRLP activity, it may be useful to encode a chimeric TCRLP protein that can be recognized by a commercially available antibody. A fusion protein may also be engineered to contain a cleavage site located between the TCRLP encoding sequence and the heterologous protein sequence, so that TCRLP may be cleaved and purified away from the heterologous moiety. In another embodiment, sequences encoding TCRLP may be synthesized, in whole or in part, using chemical methods well known in the art (see Caruthers, M.H. et al. (1980) Nucl. Acids Res. Symp. Ser. 215-223, Horn, T. et al. (1980) Nucl. Acids Res. Symp. Ser. 225-232). Alternatively, the protein itself may be produced using chemical methods to synthesize the amino acid sequence of TCRLP, or a fragment thereof. For example, peptide synthesis can be performed using various solid-phase techniques (Roberge, J.Y. et al. (1995) Science 269:202-204) and automated synthesis may be achieved, for example, using the ABI 431 A Peptide Synthesizer (Perkin Elmer). The newly synthesized peptide may be substantially purified by preparative high performance liquid chromatography (e.g., Creighton, T. (1983) Proteins. Structures and Molecular Principles. WH Freeman and Co., New York, NY). The composition ofthe synthetic peptides may be confirmed by amino acid analysis or sequencing (e.g., the Edman degradation procedure; Creighton, supra). Additionally, the amino acid sequence of TCRLP, or any part thereof, may be altered during direct synthesis and/or combined using chemical methods with sequences from other proteins, or any part thereof, to produce a variant polypeptide. In order to express a biologically active TCRLP, the nucleotide sequences encoding TCRLP or functional equivalents, may be inserted into appropriate expression vector, i.e., a vector which contains the necessary elements for the transcription and translation ofthe inserted coding sequence. Methods which are well known to those skilled in the art may be used to construct expression vectors containing sequences encoding TCRLP and appropriate transcriptional and translational control elements. These methods include in vitro recombinant DNA techniques, synthetic techniques, and in vivo genetic recombination. Such techniques are described in Sambrook, J. et al. (1989) Molecular Cloning. A Laboratory Manual, Cold Spring Harbor Press, Plainview, NY, and Ausubel, F.M. et al. (1989) Current Protocols in Molecular Biology. John Wiley & Sons, New York, NY. A variety of expression vector/host systems may be utilized to contain and express sequences encoding TCRLP. These include, but are not limited to, microorganisms such as bacteria transformed with recombinant bacteriophage, plasmid, or cosmid DNA expression vectors; yeast transformed with yeast expression vectors; insect cell systems infected with virus expression vectors (e.g., baculovirus); plant cell systems transformed with virus expression vectors (e.g., cauliflower mosaic virus, CaMV; tobacco mosaic virus, TMV) or with bacterial expression vectors (e g , Ti or pBR322 plasmids), or animal cell systems The invention is not limited by the host cell employed The "control elements" or "regulatory sequences" are those non-translated regions ofthe vector—enhancers, promoters, 5' and 3' untranslated regions—which interact with host cellular proteins to carry out transcπption and translation Such elements may vary in their strength and specificity Depending on the vector system and host utilized, any number of suitable transcπption and translation elements, including constitutive and mducible promoters, may be used. For example, when cloning in bacteπal systems, mducible promoters such as the hybrid lacZ promoter of the Bluescπpt® phagemid (Stratagene, LaJolla, CA) or pSportl™ plasmid (Gibco BRL) and the like may be used. The baculovirus polyhedπn promoter may be used in insect cells. Promoters or enhancers deπved from the genomes of plant cells (e g , heat shock, RUBISCO; and storage protein genes) or from plant viruses (e g , viral promoters or leader sequences) may be cloned into the vector In mammalian cell systems, promoters from mammalian genes or from mammalian viruses are preferable If it is necessary to generate a cell line that contains multiple copies ofthe sequence encoding TCRLP, vectors based on SV40 or EBV may be used with an appropπate selectable marker In bacteπal systems, a number of expression vectors may be selected depending upon the use intended for TCRLP For example, when large quantities of TCRLP are needed for the induction of antibodies, vectors which direct high level expression of fusion proteins that are readily purified may be used Such vectors include, but are not limited to, the multifunctional E coli cloning and expression vectors such as Bluescπpt® (Stratagene), in which the sequence encoding TCRLP may be ligated mto the vector in frame with sequences for the amino-terminal Met and the subsequent 7 residues of β-galactosidase so that a hybπd protein is produced, pIN vectors (Van Heeke, G. and S.M. Schuster (1989) J. Biol Chem. 264.5503-5509); and the like pGEX vectors (Promega, Madison, WI) may also be used to express foreign polypeptides as fusion proteins with glutathione S-transferase (GST). In general, such fusion proteins are soluble and can easily be purified from lysed cells by adsorption to glutathione-agarose beads followed by elution in the presence of free glutathione. Proteins made m such systems may be designed to include hepaπn, thrombin, or factor XA protease cleavage sites so that the cloned polypeptide of interest can be released from the GST moiety at will In the yeast, Saccharomvces cerevisiae. a number of vectors containing constitutive or mducible promoters such as alpha factor, alcohol oxidase, and PGH may be used. For reviews, see Ausubel et al. (supra) and Grant et al. (1987) Methods Enzymol. 153:516-544. In cases where plant expression vectors are used, the expression of sequences encoding TCRLP may be driven by any of a number of promoters. For example, viral promoters such as the 35S and 19S promoters of CaMV may be used alone or in combination with the omega leader sequence from TMV (Takamatsu, N. (1987) EMBO J. 6:307-311). Alternatively, plant promoters such as the small subunit of RUBISCO or heat shock promoters may be used (Coruzzi, G. et al. (1984) EMBO J. 3: 1671-1680; Broglie, R. et al. (1984) Science 224:838-843; and Winter, J. et al. (1991) Results Probl. Cell Differ. 17:85-105). These constructs can be introduced into plant cells by direct DNA transformation or pathogen-mediated transfection. Such techniques are described in a number of generally available reviews (see, for example, Hobbs, S. or Murry, L.E. in McGraw Hill Yearbook of Science and Technology (1992) McGraw Hill, New York, NY; pp. 191-196. An insect system may also be used to express TCRLP. For example, in one such system, Auto rapha californica nuclear polyhedrosis virus (AcNPV) is used as a vector to express foreign genes in Spodoptera frugiperda cells or in Trichoplusia larvae. The sequences encoding TCRLP may be cloned into a non-essential region ofthe virus, such as the polyhedrin gene, and placed under control ofthe polyhedrin promoter. Successful insertion of TCRLP will render the polyhedrin gene inactive and produce recombinant virus lacking coat protein. The recombinant viruses may then be used to infect, for example, Si. frugiperda cells or Trichoplusia larvae in which TCRLP may be expressed (Engelhard, E.K. et al. (1994) Proc. Nat. Acad. Sci. 91:3224-3227). In mammalian host cells, a number of viral-based expression systems may be utilized. In cases where an adenovirus is used as an expression vector, sequences encoding TCRLP may be ligated into an adenovirus transcription/translation complex consisting ofthe late promoter and tripartite leader sequence. Insertion in a non-essential El or E3 region ofthe viral genome may be used to obtain a viable virus which is capable of expressing TCRLP in infected host cells (Logan, J. and Shenk, T. (1984) Proc. Natl. Acad. Sci. 81 :3655-3659). In addition, transcription enhancers, such as the Rous sarcoma virus (RSV) enhancer, may be used to increase expression in mammalian host cells. Human artificial chromosomes (HACs) may also be employed to deliver larger fragments of DNA than can be contained and expressed in a plasmid. HACs of 6 to 10M are constructed and delivered via conventional delivery methods (liposomes, polycationic amino polymers, or vesicles) for therapeutic purposes. Specific initiation signals may also be used to achieve more efficient translation of sequences encoding TCRLP. Such signals include the ATG initiation codon and adjacent sequences. In cases where sequences encoding TCRLP, its initiation codon, and upstream sequences are inserted into the appropriate expression vector, no additional transcriptional or translational control signals may be needed. However, in cases where only coding sequence, or a fragment thereof, is inserted, exogenous translational control signals including the ATG initiation codon should be provided. Furthermore, the initiation codon should be in the correct reading frame to ensure translation ofthe entire insert. Exogenous translational elements and initiation codons may be of various origins, both natural and synthetic. The efficiency of expression may be enhanced by the inclusion of enhancers which are appropriate for the particular cell system which is used, such as those described in the literature (Scharf, D. et al. (1994) Results Probl. Cell Differ. 20:125-162). In addition, a host cell strain may be chosen for its ability to modulate the expression of the inserted sequences or to process the expressed protein in the desired fashion. Such modifications ofthe polypeptide include, but are not limited to, acetylation, carboxylation, glycosylation, phosphorylation, lipidation, and acylation. Post-translational processing which cleaves a "prepro" form ofthe protein may also be used to facilitate correct insertion, folding and/or function. Different host cells which have specific cellular machinery and characteristic mechanisms for post-translational activities (e.g., CHO, HeLa, MDCK, HEK293, and WI38), are available from the American Type Culture Collection (ATCC; Bethesda, MD) and may be chosen to ensure the correct modification and processing ofthe foreign protein. For long-term, high-yield production of recombinant proteins, stable expression is preferred. For example, cell lines which stably express TCRLP may be transformed using expression vectors which may contain viral origins of replication and/or endogenous expression elements and a selectable marker gene on the same or on a separate vector. Following the introduction of the vector, cells may be allowed to grow for 1-2 days in an enriched media before they are switched to selective media. The purpose ofthe selectable marker is to confer resistance to selection, and its presence allows growth and recovery of cells which successfully express the introduced sequences. Resistant clones of stably transformed cells may be proliferated using tissue culture techniques appropriate to the cell type. Any number of selection systems may be used to recover transformed cell lines. These include, but are not limited to, the herpes simplex virus thymidine kinase (Wigler, M. et al. (1977) Cell 1 1 :223-32) and adenine phosphoribosyltransferase (Lowy, I. et al. (1980) Cell 22:817-23) genes which can be employed in tk " or aprt cells, respectively. Also, antimetabolite, antibiotic or herbicide resistance can be used as the basis for selection; for example, dhfr which confers resistance to methotrexate (Wigler, M. et al. (1980) Proc. Natl. Acad. Sci. 77:3567-70); npt, which confers resistance to the aminoglycosides neomycin and G-418 (Colbere-Garapin, F. et al (1981) J. Mol. Biol. 150:1-14) and als or pat, which confer resistance to chlorsulfuron and phosphinotricin acetyltransferase, respectively (Murry, supra). Additional selectable genes have been described, for example, trpB, which allows cells to utilize indole in place of tryptophan, or hisD, which allows cells to utilize histinol in place of histidine (Hartman, S.C. and R.C. Mulligan (1988) Proc. Natl. Acad. Sci. 85:8047-51). Recently, the use of visible markers has gained popularity with such markers as anthocyanins, β glucuronidase and its substrate GUS, and luciferase and its substrate luciferin, being widely used not only to identify transformants, but also to quantify the amount of transient or stable protein expression attributable to a specific vector system (Rhodes, CA. et al. (1995) Methods Mol. Biol. 55:121-131). Although the presence/absence of marker gene expression suggests that the gene of interest is also present, its presence and expression may need to be confirmed. For example, if the sequence encoding TCRLP is inserted within a marker gene sequence, transformed cells containing sequences encoding TCRLP can be identified by the absence of marker gene function. Alternatively, a marker gene can be placed in tandem with a sequence encoding TCRLP under the control of a single promoter. Expression ofthe marker gene in response to induction or selection usually indicates expression of the tandem gene as well. Alternatively, host cells which contain the nucleic acid sequence encoding TCRLP and express TCRLP may be identified by a variety of procedures known to those of skill in the art. These procedures include, but are not limited to, DNA-DNA or DNA-RNA hybridizations and protein bioassay or immunoassay techniques which include membrane, solution, or chip based technologies for the detection and/or quantification of nucleic acid or protein. The presence of polynucleotide sequences encoding TCRLP can be detected by DNA-DNA or DNA-RNA hybridization or amplification using probes or fragments or fragments of polynucleotides encoding TCRLP. Nucleic acid amplification based assays involve the use of oligonucleotides or oligomers based on the sequences encoding TCRLP to detect transformants containing DNA or RNA encoding TCRLP. A variety of protocols for detecting and measuring the expression of TCRLP. using either polyclonal or monoclonal antibodies specific for the protein are known in the art. Examples include enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), and fluorescence activated cell sorting (FACS). A two-site, monoclonal-based immunoassay utilizing monoclonal antibodies reactive to two non-interfering epitopes on TCRLP is preferred, but a competitive binding assay may be employed. These and other assays are described, among other places, in Hampton, R. et al. (1990; Serological Methods, a Laboratory Manual APS Press, St Paul, MN) and Maddox, D.E. et al. (1983; J. Exp. Med. 158:1211-1216). A wide variety of labels and conjugation techniques are known by those skilled in the art and may be used in various nucleic acid and amino acid assays. Means for producing labeled hybridization or PCR probes for detecting sequences related to polynucleotides encoding TCRLP include oligolabeling, nick translation, end-labeling or PCR amplification using a labeled nucleotide. Alternatively, the sequences encoding TCRLP, or any fragments thereof may be cloned into a vector for the production of an mRNA probe. Such vectors are known in the art, are commercially available, and may be used to synthesize RNA probes in vitro by addition of an appropriate RNA polymerase such as T7, T3, or SP6 and labeled nucleotides. These procedures may be conducted using a variety of commercially available kits (Pharmacia & Upjohn, (Kalamazoo, MI); Promega (Madison WI); and U.S. Biochemical Corp., Cleveland, OH). Suitable reporter molecules or labels, which may be used for ease of detection, include radionuclides, enzymes, fluorescent, chemiluminescent, or chromogenic agents as well as substrates, cofactors, inhibitors, magnetic particles, and the like. Host cells transformed with nucleotide sequences encoding TCRLP may be cultured under conditions suitable for the expression and recovery ofthe protein from cell culture. The protein produced by a transformed cell may be secreted or contained intracellularly depending on the sequence and/or the vector used. As will be understood by those of skill in the art, expression vectors containing polynucleotides which encode TCRLP may be designed to contain signal sequences which direct secretion of TCRLP through a prokaryotic or eukaryotic cell membrane. Other constructions may be used to join sequences encoding TCRLP to nucleotide sequence encoding a polypeptide domain which will facilitate purification of soluble proteins. Such purification facilitating domains include, but are not limited to, metal chelating peptides such as histidine-tryptophan modules that allow purification on immobilized metals, protein A domains that allow purification on immobilized immunoglobulin, and the domain utilized in the FLAGS extension/affinity purification system (Immunex Corp., Seattle, WA). The inclusion of cleavable linker sequences such as those specific for Factor XA or enterokinase (Lnvitrogen, San Diego, CA) between the purification domain and TCRLP may be used to facilitate purification. One such expression vector provides for expression of a fusion protein containing TCRLP and a nucleic acid encoding 6 histidine residues preceding a thioredoxin or an enterokinase cleavage site. The histidine residues facilitate purification on IMAC (immobilized metal ion affinity chromatography as described in Porath, J. et al. (1992, Prot. Exp. Purif. 3: 263-281) while the enterokinase cleavage site provides a means for purifying TCRLP from the fusion protein. A discussion of vectors which contain fusion proteins is provided in Kroll, D.J. et al. (1993; DNA Cell Biol. 12:441-453). In addition to recombinant production, fragments of TCRLP may be produced by direct peptide synthesis using solid-phase techniques Merrifield J. (1963) J. Am. Chem. Soc. 85:2149-2154). Protein synthesis may be performed using manual techniques or by automation. Automated synthesis may be achieved, for example, using Applied Biosystems 431 A Peptide Synthesizer (Perkin Elmer). Various fragments of TCRLP may be chemically synthesized separately and combined using chemical methods to produce the full length molecule. THERAPEUTICS Based on the chemical and structural homology among TCRLP, human T-cell receptor beta (GI 1100182) and human T-cell receptor precursor (GI 339012), TCRLP appears to be a T cell receptor beta like protein. T cell receptor beta proteins are essential to the formation of a functional T cell receptor and play a role in antigen recognition by T cells. T cell antigen recognition is crucial to all ofthe cell-mediated immune reactions that are effected and regulated by T cells. In addition, TCRLP is expressed primarily in cells ofthe immune system. Therefore, TCRLP appears to be a at cell play a role in cancer and autoimmune disorders. Therefore, in one embodiment, TCRLP or a fragment or derivative may be administered to a subject to treat or prevent cancer. These cancers include, but are not limited to, adenocarcinoma, leukemia, lymphoma, melanoma, myeloma, sarcoma, and teratocarcinoma and particularly cancers ofthe adrenal gland, bladder, bone, brain, breast, cervix, gall bladder, gastrointestinal tract, heart, kidney, liver, lung, ovaries, pancreas, paragangliomas, parathyroid, pituitary gland, prostate, salivary gland, spleen, stomach, thyrnus, thyroid, testes, and uterus. In another embodiment, a vector capable of expressing TCRLP, or a fragment or a derivative thereof, may also be administered to a subject to treat cancers including, but not limited to, those described above. In another embodiment, an agonist of TCRLP may be administered to a subject to prevent or treat cancers including, but not limited to, those described above. In one embodiment, an antagonist of TCRLP may be administered to a subject to prevent or treat an autoimmune disorder. Such disorders may include, but are not limited to, AIDS, Addison's disease, adult respiratory distress syndrome, allergies, anemia, asthma, atherosclerosis, bronchitis, cholecystitis, Crohn's disease, ulcerative colitis, atopic dermatitis, dermatomyositis, diabetes mellitus, emphysema, erythema nodosum, atrophic gastritis, glomerulonephritis, gout, Graves' disease, hypereosinophilia, irritable bowel syndrome, lupus erythematosus, multiple sclerosis, myasthenia gravis, myocardial or pericardial inflammation, osteoarthritis, osteoporosis, pancreatitis, polymyositis, rheumatoid arthritis, scleroderma, Sjogren's syndrome, and autoimmune thyroiditis; complications of cancer, hemodialysis, and extracorporeal circulation; viral, bacterial, fungal, parasitic, protozoal, and helminthic infections; and trauma. In one aspect, an antibody which specifically binds TCRLP may be used directly as an antagonist or indirectly as a targeting or delivery mechanism for bringing a pharmaceutical agent to cells or tissue which express TCRLP. In another embodiment, a vector expressing the complement ofthe polynucleotide encoding TCRLP may be administered to a subject to treat or prevent an autoimmune disorder including, but not limited to, those described above. In other embodiments, any ofthe proteins, antagonists, antibodies, agonists, complementary sequences or vectors ofthe invention may be administered in combination with other appropriate therapeutic agents. Selection ofthe appropriate agents for use in combination therapy may be made by one of ordinary skill in the art, according to conventional pharmaceutical principles. The combination of therapeutic agents may act synergistically to effect the treatment or prevention ofthe various disorders described above. Using this approach, one may be able to achieve therapeutic efficacy with lower dosages of each agent, thus reducing the potential for adverse side effects. An antagonist of TCRLP may be produced using methods which are generally known in the art. In particular, purified TCRLP may be used to produce antibodies or to screen libraries of pharmaceutical agents to identify those which specifically bind TCRLP. Antibodies to TCRLP may be generated using methods that are well known in the art. Such antibodies may include, but are not limited to, polyclonal, monoclonal, chimeric, single chain, Fab fragments, and fragments produced by a Fab expression library. Neutralizing antibodies, (i.e., those which inhibit dimer formation) are especially preferred for therapeutic use. For the production of antibodies, various hosts including goats, rabbits, rats, mice, humans, and others, may be immunized by injection with TCRLP or any fragment or oligopeptide thereof which has immunogenic properties. Depending on the host species, various adjuvants may be used to increase immunological response. Such adjuvants include, but are not limited to, Freund's, mineral gels such as aluminum hydroxide, and surface active substances such as lysolecithin, pluronic polyols, polyanions, peptides, oil emulsions, keyhole limpet hemocyanin, and dinitrophenol Among adjuvants used in humans, BCG (bacilli Calmette-Guerin) and Corynebacterium parvum are especially preferable. It is preferred that the oligopeptides, peptides, or fragments used to induce antibodies to TCRLP have an amino acid sequence consisting of at least five amino acids and more preferably at least 10 amino acids. It is also preferable that they are identical to a portion ofthe amino acid sequence ofthe natural protein, and they may contain the entire amino acid sequence of a small, naturally occurring molecule. Short stretches of TCRLP amino acids may be fused with those of another protein such as keyhole limpet hemocyanin and antibody produced against the chimeric molecule. Monoclonal antibodies to TCRLP may be prepared using any technique which provides for the production of antibody molecules by continuous cell lines in culture. These include, but are not limited to, the hybridoma technique, the human B-cell hybridoma technique, and the EBV-hybridoma technique (Kohler, G. et al. (1975) Nature 256:495-497; Kozbor, D. et al. (1985) J. Immunol. Methods 81:31-42; Cote, R.J. et al. (1983) Proc. Natl. Acad. Sci. 80:2026-2030; Cole, S.P. et al. (1984) Mol. Cell Biol. 62: 109-120). In addition, techniques developed for the production of "chimeric antibodies", the splicing of mouse antibody genes to human antibody genes to obtain a molecule with appropriate antigen specificity and biological activity can be used (Morrison, S.L. et al. (1984) Proc. Natl. Acad. Sci. 81 :6851-6855; Neuberger, M.S. et al. (1984) Nature 312:604-608; Takeda, S. et al. (1985) Nature 314:452-454). Alternatively, techniques described for the production of single chain antibodies may be adapted, using methods known in the art, to produce TCRLP-specific single chain antibodies. Antibodies with related specificity, but of distinct idiotypic composition, may be generated by chain shuffling from random combinatorial immunoglobin libraries (Burton D.R. (1991) Proc. Natl Acad. Sci. 88: 1 1 120-3). Antibodies may also be produced by inducing in vivo production in the lymphocyte population or by screening immunoglobulin libraries or panels of highly specific binding reagents as disclosed in the literature (Orlandi, R. et al (1989) Proc. Natl. Acad. Sci. 86: 3833-3837; Winter, G. et al. (1991) Nature 349:293-299). Antibody fragments which contain specific binding sites for TCRLP may also be generated. For example, such fragments include, but are not limited to, the F(ab')2 fragments which can be produced by pepsin digestion ofthe antibody molecule and the Fab fragments which can be generated by reducing the disulfide bridges ofthe F(ab')2 fragments. Alternatively, Fab expression libraries may be constructed to allow rapid and easy identification of monoclonal Fab fragments with the desired specificity (Huse, W.D. et al. (1989) Science 254: 1275-1281). Various immunoassays may be used for screening to identify antibodies having the desired specificity. Numerous protocols for competitive binding or immunoradiometric assays using either polyclonal or monoclonal antibodies with established specificities are well known in the art. Such immunoassays typically involve the measurement of complex formation between TCRLP and its specific antibody. A two-site, monoclonal-based immunoassay utilizing monoclonal antibodies reactive to two non-interfering TCRLP epitopes is preferred, but a competitive binding assay may also be employed (Maddox, supra). In another embodiment ofthe invention, the polynucleotides encoding TCRLP, or any fragment or complement thereof, may be used for therapeutic purposes. In one aspect, the complement ofthe polynucleotide encoding TCRLP may be used in situations in which it would be desirable to block the transcription ofthe mRNA. In particular, cells may be transformed with sequences complementary to polynucleotides encoding TCRLP. Thus, complementary molecules or fragments may be used to modulate TCRLP activity, or to achieve regulation of gene function. Such technology is now well known in the art, and sense or antisense oligonucleotides or larger fragments, can be designed from various locations along the coding or control regions of sequences encoding TCRLP. Expression vectors derived from retro viruses, adenovirus, herpes or vaccinia viruses, or from various bacterial plasmids may be used for delivery of nucleotide sequences to the targeted organ, tissue or cell population. Methods which are well known to those skilled in the art can be used to construct vectors which will express nucleic acid sequence which is complementary to the polynucleotides ofthe gene encoding TCRLP. These techniques are described both in Sambrook et al (supra) and in Ausubel et al (supra) Genes encoding TCRLP can be turned off by transforming a cell or tissue with expression vectors which express high levels of a polynucleotide or fragment thereof which encodes TCRLP. Such constructs may be used to introduce untranslatable sense or antisense sequences into a cell. Even in the absence of integration into the DNA, such vectors may continue to transcπbe RNA molecules until they are disabled by endogenous nucleases. Transient expression may last for a month or more with a non-replicating vector and even longer if appropπate replication elements are part ofthe vector system. As mentioned above, modifications of gene expression can be obtained by designing complementary sequences or antisense molecules (DNA, RNA, or PNA) to the control, 5' or regulatory regions ofthe gene encoding TCRLP (signal sequence, promoters, enhancers, and introns). Oligonucleotides derived from the transcπption initiation site, e.g., between positions -10 and +10 from the start site, are preferred. Similarly, inhibition can be achieved using "tπple helix" base-paiπng methodology. Triple helix paiπng is useful because it causes inhibition ofthe ability ofthe double helix to open sufficiently for the binding of polymerases, transcπption factors, or regulatory molecules Recent therapeutic advances using tπplex DNA have been descπbed in the literature (Gee, J.E. et al. (1994) In. Huber, B.E. and B.I. Carr, Molecular and Immunologic Approaches. Futura Publishing Co., Mt. Kisco, NY). The complementary sequence or antisense molecule may also be designed to block translation of mRNA by preventing the transcπpt from binding to πbosomes. Ribozymes, enzymatic RNA molecules, may also be used to catalyze the specific cleavage of RNA. The mechanism of πbozyme action involves sequence-specific hybπdization ofthe πbozyme molecule to complementary target RNA, followed by endonucleolytic cleavage Examples which may be used include engineered hammerhead motif πbozyme molecules that can specifically and efficiently catalyze endonucleolytic cleavage of sequences encoding TCRLP. Specific πbozyme cleavage sites withm any potential RNA target are initially identified by scanning the target molecule for πbozyme cleavage sites which include the following sequences: GUA, GUU, and GUC. Once identified, short RNA sequences of between 15 and 20 πbonucleotides corresponding to the region ofthe target gene containing the cleavage site may be evaluated for secondary structural features which may render the oligonucleotide inoperable. The suitability of candidate targets may also be evaluated by testing accessibility to hybπdization with complementary oligonucleotides using πbonuclease protection assays. Complementary ribonucleic acid molecules and ribozymes ofthe invention may be prepared by any method known in the art for the synthesis of nucleic acid molecules. These include techniques for chemically synthesizing oligonucleotides such as solid phase phosphoramidite chemical synthesis. Alternatively, RNA molecules may be generated by in vitro and in vivo transcription of DNA sequences encoding TCRLP. Such DNA sequences may be incorporated into a wide variety of vectors with suitable RNA polymerase promoters such as T7 or SP6. Alternatively, these cDNA constructs that synthesize complementary RNA constitutively or inducibly can be introduced into cell lines, cells, or tissues. RNA molecules may be modified to increase intracellular stability and half-life. Possible modifications include, but are not limited to, the addition of flanking sequences at the 5' and/or 3' ends ofthe molecule or the use of phosphorothioate or 2' O-methyl rather than phosphodiesterase linkages within the backbone ofthe molecule. This concept is inherent in the production of PNAs and can be extended in all of these molecules by the inclusion of nontraditional bases such as inosine, queosine, and wybutosine, as well as acetyl-, methyl-, thio-, and similarly modified forms of adenine, cytidine, guanine, thymine, and uridine which are not as easily recognized by endogenous endonucleases. Many methods for introducing vectors into cells or tissues are available and equally suitable for use jn vivo, in vitro, and ex vivo. For ex vivo therapy, vectors may be introduced into stem cells taken from the patient and clonally propagated for autologous transplant back into that same patient. Delivery by transfection, by liposome injections or polycationic amino polymers (Goldman, C.K. et al. (1997) Nature Biotechnology 15:462-66; incorporated herein by reference) may be achieved using methods which are well known in the art. Any ofthe therapeutic methods described above may be applied to any subject in need of such therapy, including, for example, mammals such as dogs, cats, cows, horses, rabbits, monkeys, and most preferably, humans. An additional embodiment ofthe invention relates to the administration of a pharmaceutical composition, in conjunction with a pharmaceutically acceptable carrier, for any of the therapeutic effects discussed above. Such pharmaceutical compositions may consist of TCRLP, antibodies to TCRLP, mimetics, agonists, antagonists, or inhibitors of TCRLP. The compositions may be administered alone or in combination with at least one other agent, such as stabilizing compound, which may be administered in any sterile, biocompatible pharmaceutical carrier, including, but not limited to, saline, buffered saline, dextrose, and water. The compositions may be administered to a patient alone, or in combination with other agents, drugs or hormones. The pharmaceutical compositions utilized in this invention may be administered by any number of routes including, but not limited to, oral, intravenous, intramuscular, intra-arterial, intramedullary, intrathecal, intraventricular, transdermal, subcutaneous, intraperitoneal, intranasal, enteral, topical, sublingual, or rectal means. In addition to the active ingredients, these pharmaceutical compositions may contain suitable pharmaceutically-acceptable carriers comprising excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Further details on techniques for formulation and administration may be found in the latest edition of Remington's Pharmaceutical Sciences (Maack Publishing Co., Easton, PA). Pharmaceutical compositions for oral administration can be formulated using pharmaceutically acceptable carriers well known in the art in dosages suitable for oral administration. Such carriers enable the pharmaceutical compositions to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions, and the like, for ingestion by the patient. Pharmaceutical preparations for oral use can be obtained through combination of active compounds with solid excipient, optionally grinding a resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients are carbohydrate or protein fillers, such as sugars, including lactose, sucrose, mannitol, or sorbitol; starch from corn, wheat, rice, potato, or other plants; cellulose, such as methyl cellulose, hydroxypropylmethyl-cellulose, or sodium carboxymethylcellulose; gums including arabic and tragacanth; and proteins such as gelatin and collagen. If desired, disintegrating or solubilizing agents may be added, such as the cross-linked polyvinyl pyrrolidone, agar, alginic acid, or a salt thereof, such as sodium alginate. Dragee cores may be used in conjunction with suitable coatings, such as concentrated sugar solutions, which may also contain gum arabic, talc, polyvinylpyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for product identification or to characterize the quantity of active compound, i.e., dosage. Pharmaceutical preparations which can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a coating, such as glycerol or sorbitol Push-fit capsules can contain active ingredients mixed with a filler or binders, such as lactose or starches, lubricants, such as talc or magnesium stearate, and, optionally, stabilizers. In soft capsules, the active compounds may be dissolved or suspended in suitable liquids, such as fatty oils, liquid, or liquid polyethylene glycol with or without stabilizers. Pharmaceutical formulations suitable for parenteral administration may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hanks's solution, Ringer's solution, or physiologically buffered saline. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Additionally, suspensions ofthe active compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Non-lipid polycationic amino polymers may also be used for delivery. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility ofthe compounds to allow for the preparation of highly concentrated solutions. For topical or nasal administration, penetrants appropriate to the particular barrier to be permeated are used in the formulation. Such penetrants are generally known in the art. The pharmaceutical compositions ofthe present invention may be manufactured in a manner that is known in the art, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, or lyophilizing processes. The pharmaceutical composition may be provided as a salt and can be formed with many acids, including but not limited to, hydrochloric, sulfuric, acetic, lactic, tartaric, malic, succinic, etc. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free base forms. In other cases, the preferred preparation may be a lyophilized powder which may contain any or all ofthe following: 1-50 mM histidine, 0.1%-2% sucrose, and 2-7% mannitol, at a pH range of 4.5 to 5.5, that is combined with buffer prior to use. After pharmaceutical compositions have been prepared, they can be placed in an appropriate container and labeled for treatment of an indicated condition. For administration of TCRLP, such labeling would include amount, frequency, and method of administration. Pharmaceutical compositions suitable for use in the invention include compositions wherein the active ingredients are contained in an effective amount to achieve the intended purpose. The determination of an effective dose is well within the capability of those skilled in the art. For any compound, the therapeutically effective dose can be estimated initially either in cell culture assays, e.g., of neoplastic cells, or in animal models, usually mice, rabbits, dogs, or pigs. The animal model may also be used to determine the appropriate concentration range and route of administration. Such information can then be used to determine useful doses and routes for administration in humans. A therapeutically effective dose refers to that amount of active ingredient, for example TCRLP or fragments thereof, antibodies of TCRLP, agonists, antagonists or inhibitors of TCRLP, which ameliorates the symptoms or condition. Therapeutic efficacy and toxicity may be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., ED50 (the dose therapeutically effective in 50% ofthe population) and LD50 (the dose lethal to 50% ofthe population). The dose ratio between therapeutic and toxic effects is the therapeutic index, and it can be expressed as the ratio, LD50/ED50. Pharmaceutical compositions which exhibit large therapeutic indices are preferred. The data obtained from cell culture assays and animal studies is used in formulating a range of dosage for human use. The dosage contained in such compositions is preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage varies within this range depending upon the dosage form employed, sensitivity ofthe patient, and the route of administration. The exact dosage will be determined by the practitioner, in light of factors related to the subject that requires treatment. Dosage and administration are adjusted to provide sufficient levels ofthe active moiety or to maintain the desired effect. Factors which may be taken into account include the severity ofthe disease state, general health ofthe subject, age, weight, and gender ofthe subject, diet, time and frequency of administration, drug combination(s), reaction sensitivities, and tolerance/response to therapy. Long-acting pharmaceutical compositions may be administered every 3 to 4 days, every week, or once every two weeks depending on half-life and clearance rate ofthe particular formulation. Normal dosage amounts may vary from 0.1 to 100,000 micrograms, up to a total dose of about 1 g, depending upon the route of administration. Guidance as to particular dosages and methods of delivery is provided in the literature and generally available to practitioners in the art. Those skilled in the art will employ different formulations for nucleotides than for proteins or their inhibitors. Similarly, delivery of polynucleotides or polypeptides will be specific to particular cells, conditions, locations, etc. DIAGNOSTICS In another embodiment, antibodies which specifically bind TCRLP may be used for the diagnosis of conditions or diseases characterized by expression of TCRLP, or in assays to monitor patients being treated with TCRLP, agonists, antagonists or inhibitors. The antibodies useful for diagnostic purposes may be prepared in the same manner as those described above for therapeutics. Diagnostic assays for TCRLP include methods which utilize the antibody and a label to detect TCRLP in human body fluids or extracts of cells or tissues. The antibodies may be used with or without modification, and may be labeled by joining them, either covalently or non-covalently, with a reporter molecule. A wide variety of reporter molecules which are known in the art may be used, several of which are described above. A variety of protocols including ELISA, RIA, and FACS for measuring TCRLP are known in the art and provide a basis for diagnosing altered or abnormal levels of TCRLP expression. Normal or standard values for TCRLP expression are established by combining body fluids or cell extracts taken from normal mammalian subjects, preferably human, with antibody to TCRLP under conditions suitable for complex formation The amount of standard complex formation may be quantified by various methods, but preferably by photometric, means. Quantities of TCRLP expressed in subject, control and disease, samples from biopsied tissues are compared with the standard values. Deviation between standard and subject values establishes the parameters for diagnosing disease. In another embodiment ofthe invention, the polynucleotides encoding TCRLP may be used for diagnostic purposes. The polynucleotides which may be used include oligonucleotide sequences, complementary RNA and DNA molecules, and PNAs. The polynucleotides may be used to detect and quantitate gene expression in biopsied tissues in which expression of TCRLP may be correlated with disease. The diagnostic assay may be used to distinguish between absence, presence, and excess expression of TCRLP, and to monitor regulation of TCRLP levels during therapeutic intervention. In one aspect, hybridization with PCR probes which are capable of detecting polynucleotide sequences, including genomic sequences, encoding TCRLP or closely related molecules, may be used to identify nucleic acid sequences which encode TCRLP. The specificity ofthe probe, whether it is made from a highly specific region, e.g., 10 unique nucleotides in the 5' regulatory region, or a less specific region, e.g., especially in the 3' coding region, and the stringency ofthe hybridization or amplification (maximal, high, intermediate, or low) will determine whether the probe identifies only naturally occurring sequences encoding TCRLP, alleles, or related sequences. Probes may also be used for the detection of related sequences, and should preferably contain at least 50% ofthe nucleotides from any ofthe TCRLP encoding sequences. The hybridization probes ofthe subject invention may be DNA or RNA and derived from the nucleotide sequence of SEQ ID NO: 2 or from genomic sequence including promoter, enhancer elements, and introns ofthe naturally occurring TCRLP. Means for producing specific hybridization probes for DNAs encoding TCRLP include the cloning of nucleic acid sequences encoding TCRLP or TCRLP derivatives into vectors for the production of mRNA probes. Such vectors are known in the art, commercially available, and may be used to synthesize RNA probes in vitro by means ofthe addition ofthe appropriate RNA polymerases and the appropriate labeled nucleotides. Hybridization probes may be labeled by a variety of reporter groups, for example, radionuclides such as 32P or 35S, or enzymatic labels, such as alkaline phosphatase coupled to the probe via avidin/biotin coupling systems, and the like. Polynucleotide sequences encoding TCRLP may be used for the diagnosis of conditions or disorders which are associated with expression of TCRLP. Examples of such conditions or disorders include adenocarcinoma, leukemia, lymphoma, melanoma, myeloma, sarcoma, and teratocarcinoma and particularly cancers ofthe adrenal gland, bladder, bone, brain, breast, cervix, gall bladder, gastrointestinal tract, heart, kidney, liver, lung, ovaries, pancreas, paragangliomas, parathyroid, pituitary gland, prostate, salivary gland, spleen, stomach, thyrnus, thyroid, testes, and uterus; and AIDS, Addison's disease, adult respiratory distress syndrome, allergies, anemia, asthma, atherosclerosis, bronchitis, cholecystitis, Crohn's disease, ulcerative colitis, atopic dermatitis, dermatomyositis, diabetes mellitus, emphysema, erythema nodosum, atrophic gastritis, glomerulonephritis, gout, Graves' disease, hypereosinophilia, irritable bowel syndrome, lupus erythematosus, multiple sclerosis, myasthenia gravis, myocardial or pericardial inflammation, osteoarthritis, osteoporosis, pancreatitis, polymyositis, rheumatoid arthritis, scleroderma, Sjόgren's syndrome, and autoimmune thyroiditis; complications of cancer, hemodialysis, and extracorporeal circulation; viral, bacterial, fungal, parasitic, protozoal, and helminthic infections; and trauma. The polynucleotide sequences encoding TCRLP may be used in Southern or northern analysis, dot blot, or other membrane-based technologies; in PCR technologies; or in dipstick, pin, ELISA assays or microarrays utilizing fluids or tissues from patient biopsies to detect altered TCRLP expression. Such qualitative or quantitative methods are well known in the art. In a particular aspect, the nucleotide sequences encoding TCRLP may be useful in assays that detect activation or induction of various cancers, particularly those mentioned above. The nucleotide sequences encoding TCRLP may be labeled by standard methods, and added to a fluid or tissue sample from a patient under conditions suitable for the formation of hybridization complexes. After a suitable incubation period, the sample is washed and the signal is quantitated and compared with a standard value. If the amount of signal in the biopsied or extracted sample is significantly altered from that of a comparable control sample, the nucleotide sequences have hybridized with nucleotide sequences in the sample, and the presence of altered levels of nucleotide sequences encoding TCRLP in the sample indicates the presence ofthe associated disease. Such assays may also be used to evaluate the efficacy of a particular therapeutic treatment regimen in animal studies, in clinical trials, or in monitoring the treatment of an individual patient. in order to provide a basis for the diagnosis of disease associated with expression of TCRLP, a normal or standard profile for expression is established. This may be accomplished by combining body fluids or cell extracts taken from normal subjects, either animal or human, with a sequence, or a fragment thereof, which encodes TCRLP, under conditions suitable for hybridization or amplification. Standard hybridization may be quantified by comparing the values obtained from normal subjects with those from an experiment where a known amount of a substantially purified polynucleotide is used. Standard values obtained from normal samples may be compared with values obtained from samples from patients who are symptomatic for disease. Deviation between standard and subject values is used to establish the presence of disease. Once disease is established and a treatment protocol is initiated, hybridization assays may be repeated on a regular basis to evaluate whether the level of expression in the patient begins to approximate that which is observed in the normal patient. The results obtained from successive assays may be used to show the efficacy of treatment over a period ranging from several days to months. With respect to cancer, the presence of a relatively high amount of transcript in biopsied tissue from an individual may indicate a predisposition for the development ofthe disease, or may provide a means for detecting the disease prior to the appearance of actual clinical symptoms. A more definitive diagnosis of this type may allow health professionals to employ preventative measures or aggressive treatment earlier thereby preventing the development or further progression of the cancer. Additional diagnostic uses for oligonucleotides designed from the sequences encoding TCRLP may involve the use of PCR. Such oligomers may be chemically synthesized, generated enzymatically, or produced in vitro. Oligomers will preferably consist of two nucleotide sequences, one with sense orientation (5'->3') and another with antisense (3'<-5'), employed under optimized conditions for identification of a specific gene or condition. The same two oligomers, nested sets of oligomers, or even a degenerate pool of oligomers may be employed under less stringent conditions for detection and/or quantitation of closely related DNA or RNA sequences. Methods which may also be used to quantitate the expression of TCRLP include radiolabeling or biotinylating nucleotides, coamplification of a control nucleic acid, and standard curves onto which the experimental results are interpolated (Melby, P.C. et al (1993) J. Immunol. Methods, 159:235-244; Duplaa, C. et al. (1993) Anal. Biochem. 229-236). The speed of quantitation of multiple samples may be accelerated by running the assay in an ELISA format where the oligomer of interest is presented in various dilutions and a spectrophotometric or colorimetric response gives rapid quantitation. In further embodiments, an oligonucleotide derived from any ofthe polynucleotide sequences described herein may be used as a target in a microarray. The microarray can be used to monitor the expression level of large numbers of genes simultaneously (to produce a transcript image), and to identify genetic variants, mutations and polymorphisms. This information will be useful in determining gene function, understanding the genetic basis of disease, diagnosing disease, and in developing and monitoring the activity of therapeutic agents (Heller, R. et al (1997) Proc. Natl. Acad. Sci. 94:2150-55) . In one embodiment, the microarray is prepared and used according to the methods described in PCT application W095/11995 (Chee et al), Lockhart, D. J. et al. (1996; Nat. Biotech. 14: 1675-1680) and Schena, M. et al (1996; Proc. Natl. Acad. Sci. 93: 10614-10619), all of which are incorporated herein in their entirety by reference. The microarray is preferably composed of a large number of unique, single-stranded nucleic acid sequences, usually either synthetic antisense oligonucleotides or fragments of cDNAs, fixed to a solid support. The oligonucleotides are preferably about 6-60 nucleotides in length, more preferably 15-30 nucleotides in length, and most preferably about 20-25 nucleotides in length. For a certain type of microarray, it may be preferable to use oligonucleotides which are only 7-10 nucleotides in length. The microarray may contain oligonucleotides which cover the known 5', or 3', sequence, sequential oligonucleotides which cover the full length sequence; or unique oligonucleotides selected from particular areas along the length ofthe sequence. Polynucleotides used in the microarray may be oligonucleotides that are specific to a gene or genes of interest in which at least a fragment ofthe sequence is known or that are specific to one or more unidentified cDNAs which are common to a particular cell type, developmental or disease state. In order to produce oligonucleotides to a known sequence for a microarray, the gene of interest is examined using a computer algorithm which starts at the 5' or more preferably at the 3' end ofthe nucleotide sequence. The algorithm identifies oligomers of defined length that are unique to the gene, have a GC content within a range suitable for hybridization, and lack predicted secondary structure that may interfere with hybridization. In certain situations it may be appropriate to use pairs of oligonucleotides on a microarray. The "pairs" will be identical, except for one nucleotide which preferably is located in the center ofthe sequence. The second oligonucleotide in the pair (mismatched by one) serves as a control. The number of oligonucleotide pairs may range from two to one million. The oligomers are synthesized at designated areas on a substrate using a light-directed chemical process. The substrate may be paper, nylon or other type of membrane, filter, chip, glass slide or any other suitable solid support. In another aspect, an oligonucleotide may be synthesized on the surface of the substrate by using a chemical coupling procedure and an ink jet application apparatus, as described in PCT application W095/251116 (Baldeschweiler et al) which is incorporated herein in its entirety by reference. In another aspect, a "gridded" array analogous to a dot (or slot) blot may be used to arrange and link cDNA fragments or oligonucleotides to the surface of a substrate using a vacuum system, thermal, UV, mechanical or chemical bonding procedures. An array, such as those described above, may be produced by hand or by using available devices (slot blot or dot blot apparatus), materials (any suitable solid support), and machines (including robotic instruments), and may contain 8, 24, 96, 384, 1536 or 6144 oligonucleotides, or any other number between two and one million which lends itself to the efficient use of commercially available instrumentation. In order to conduct sample analysis using a microarray, the RNA or DNA from a biological sample is made into hybridization probes. The mRNA is isolated, and cDNA is produced and used as a template to make antisense RNA (aRNA). The aRNA is amplified in the presence of fluorescent nucleotides, and labeled probes are incubated with the microarray so that the probe sequences hybridize to complementary oligonucleotides ofthe microarray. Incubation conditions are adjusted so that hybridization occurs with precise complementary matches or with various degrees of less complementarity. After removal of nonhybridized probes, a scanner is used to determine the levels and patterns of fluorescence. The scanned images are examined to determine degree of complementarity and the relative abundance of each oligonucleotide sequence on the microarray. The biological samples may be obtained from any bodily fluids (such as blood, urine, saliva, phlegm, gastric juices, etc.), cultured cells, biopsies, or other tissue preparations. A detection system may be used to measure the absence, presence, and amount of hybridization for all ofthe distinct sequences simultaneously. This data may be used for large scale correlation studies on the sequences, mutations, variants, or polymorphisms among samples. In another embodiment ofthe invention, the nucleic acid sequences which encode TCRLP may also be used to generate hybridization probes which are useful for mapping the naturally occurring genomic sequence. The sequences may be mapped to a particular chromosome, to a specific region of a chromosome or to artificial chromosome constructions, such as human artificial chromosomes (HACs), yeast artificial chromosomes (YACs), bacterial artificial chromosomes (BACs), bacterial PI constructions or single chromosome cDNA libraries as reviewed in Price, CM. (1993) Blood Rev. 7: 127-134, and Trask, B.J. (1991) Trends Genet. 7:149-154. Fluorescent in situ hybridization (FISH as described in Verma et al. (1988) Human Chromosomes: A Manual of Basic Techniques. Pergamon Press, New York, NY) may be correlated with other physical chromosome mapping techniques and genetic map data. Examples of genetic map data can be found in various scientific journals or at Online Mendelian Inheritance in Man (OMIM). Correlation between the location ofthe gene encoding TCRLP on a physical chromosomal map and a specific disease , or predisposition to a specific disease, may help delimit the region of DNA associated with that genetic disease. The nucleotide sequences ofthe subject invention may be used to detect differences in gene sequences between normal, carrier, or affected individuals. In situ hybridization of chromosomal preparations and physical mapping techniques such as linkage analysis using established chromosomal markers may be used for extending genetic maps. Often the placement of a gene on the chromosome of another mammalian species, such as mouse, may reveal associated markers even if the number or arm of a particular human chromosome is not known. New sequences can be assigned to chromosomal arms, or parts thereof, by physical mapping. This provides valuable information to investigators searching for disease genes using positional cloning or other gene discovery techniques. Once the disease or syndrome has been crudely localized by genetic linkage to a particular genomic region, for example, AT to 1 lq22-23 (Gatti, R.A. et al. (1988) Nature 336:577-580), any sequences mapping to that area may represent associated or regulatory genes for further investigation. The nucleotide sequence ofthe subject invention may also be used to detect differences in the chromosomal location due to translocation, inversion, etc. among normal, carrier, or affected individuals. In another embodiment of the invention, TCRLP, its catalytic or immunogenic fragments or oligopeptides thereof, can be used for screening libraries of compounds in any of a variety of drug screening techniques. The fragment employed in such screening may be free in solution, affixed to a solid support, borne on a cell surface, or located intracellularly. The formation of binding complexes, between TCRLP and the agent being tested, may be measured. Another technique for drug screening which may be used provides for high throughput screening of compounds having suitable binding affinity to the protein of interest as described in published PCT application WO84/03564. In this method, as applied to TCRLP large numbers of different small test compounds are synthesized on a solid substrate, such as plastic pins or some other surface. The test compounds are reacted with TCRLP, or fragments thereof, and washed. Bound TCRLP is then detected by methods well known in the art. Purified TCRLP can also be coated directly onto plates for use in the aforementioned drug screening techniques. Alternatively, non-neutralizing antibodies can be used to capture the peptide and immobilize it on a solid support. In another embodiment, one may use competitive drug screening assays in which neutralizing antibodies capable of binding TCRLP specifically compete with a test compound for binding TCRLP. In this manner, the antibodies can be used to detect the presence of any peptide which shares one or more antigenic determinants with TCRLP. In additional embodiments, the nucleotide sequences which encode TCRLP may be used in any molecular biology techniques that have yet to be developed, provided the new techniques rely on properties of nucleotide sequences that are currently known, including, but not limited to, -3i such properties as the triplet genetic code and specific base pair interactions. The examples below are provided to illustrate the subject invention and are not included for the purpose of limiting the invention. EXAMPLES I TONGTUT01 cDNA Library Construction The TONGTUT01 cDNA library was constructed from tongue tumor tissue obtained from a 36-year-old Caucasian male during a hemiglossectomy. The pathology report indicated recurrent invasive grade 2 squamous-cell carcinoma forming a mass 2.5 x 2 x 1.3 cm in the right tongue. The frozen tissue was homogenized and lysed using a Brinkmann Homogenizer Polytron-PT 3000 (Brinkmann Instruments, Inc. Westbury NY) in guanidinium isothiocyanate solution. The lysates were extracted once with acid phenol at pH 4.0 using Stratagene' s RNA isolation protocol (Stratagene Inc, San Diego CA). The RNA was extracted twice with an equal volume of acid phenol, reprecipitated using 0.3 M sodium acetate and 2.5 volumes of ethanol, resuspended in DEPC-treated water and DNase treated for 25 min at 37 °C. mRNAs were isolated using the Qiagen Oligotex kit (QIAGEN Inc,) and used to construct the cDNA library. The mRNA was handled according to the recommended protocols in the Superscript Plasmid System for cDNA Synthesis and Plasmid Cloning (Cat. #18248-013, Gibco BRL). cDNAs were fractionated on a Sepharose CL4B column (Cat. #275105-01, Pharmacia), and those cDNAs exceeding 400 bp were ligated into pSport I. The plasmid pSport I was subsequently transformed into DH5a™ competent cells (Cat. #18258-012, Gibco/BRL). II Isolation and Sequencing of cDNA Clones Plasmid DNA was released from the cells and purified using the REAL Prep 96 Plasmid Kit for Rapid Extraction Alkaline Lysis Plasmid Minipreps (Catalog #26173, QIAGEN, Inc.). The recommended protocol was employed except for the following changes: 1) the bacteria were cultured in 1 ml of sterile Teπific Broth (Catalog #22711, Gibco/BRL) with carbenicillin at 25 mg L and glycerol at 0.4%; 2) after inoculation, the cultures were incubated for 19 hours and at the end of incubation, the cells were lysed with 0.3 ml of lysis buffer; and 3) following isopropanol precipitation, the plasmid DNA pellet was resuspended in 0.1 ml of distilled water. After the last step in the protocol, samples were transferred to a 96-well block for storage at 4° C. The cDNAs were sequenced by the method of Sanger et al. (1975, J. Mol Biol. 94:441f), using a Hamilton Micro Lab 2200 (Hamilton, Reno, NV) in combination with Peltier Thermal Cyclers (PTC200 from MJ Research, Watertown, MA) and Applied Biosystems 377 DNA Sequencing Systems. III Homology Searching of cDNA Clones and Their Deduced Proteins The nucleotide sequences ofthe Sequence Listing or amino acid sequences deduced from them were used as query sequences against databases such as GenBank, SwissProt, BLOCKS, and Pima II. These databases which contain previously identified and annotated sequences were searched for regions of homology (similarity) using BLAST, which stands for Basic Local Alignment Search Tool (Altschul SF (1993) J Mol Evol 36:290-300; Altschul, SF et al (1990) J Mol Biol 215:403-10). BLAST produces alignments of both nucleotide and amino acid sequences to determine sequence similarity. Because ofthe local nature ofthe alignments, BLAST is especially useful in determining exact matches or in identifying homologs which may be of prokaryotic (bacterial) or eukaryotic (animal, fungal or plant) origin. Other algorithms such as the one described in Smith RF and TF Smith (1992 Protein Engineering 5:35-51), incorporated herein by reference, can be used when dealing with primary sequence patterns and secondary structure gap penalties. As disclosed in this application, the minimum length ofthe sequences in the Sequence Listing is 49 nucleotides, and the upper limit of uncalled bases where N is recorded rather than A, C, G, or T is 12%. The BLAST approach, as detailed in Karlin and Altschul (1993; Proc Nat Acad Sci 90:5873-7) and incorporated herein by reference searches matches between a query sequence and a database sequence, to evaluate the statistical significance of any matches found, and to report only those matches which satisfy the user-selected threshold of significance. In this application, threshold was set at 10 "25 for nucleotides and 10 "14 for peptides. Incyte nucleotide sequence were searched against the GenBank databases for primate (pri), rodent (rod), and mammalian sequences (mam), and deduced amino acid sequences from the same clones are searched against GenBank functional protein databases, mammalian (mamp), vertebrate (vrtp) and eukaryote (eukp), for homology. The relevant database for a particular match were reported as a GIxxx+p (where xxx is pri, rod, etc and if present, p = peptide) as shown in Table 1. IV Northern Analysis Northern analysis is a laboratory technique used to detect the presence of a transcript of a gene and involves the hybridization of a labeled nucleotide sequence to a membrane on which RNAs from a particular cell type or tissue have been bound (Sambrook et al, supra). Analogous computer techniques using BLAST (Altschul, S.F. (1993) J.Mol.Evol 36:290- 300; Altschul, S.F. et al. (1990) J.MolEvol 215:403-410) are used to search for identical or related molecules in nucleotide databases such as GenBank or the LIFESEQ™ database (Incyte Pharmaceuticals). This analysis is much faster than multiple, membrane-based hybridizations. In addition, the sensitivity ofthe computer search can be modified to determine whether any particular match is categorized as exact or homologous. The basis ofthe search is the product score which is defined as: % sequence identity x % maximum BLAST score 100 The product score takes into account both the degree of similarity between two sequences and the length ofthe sequence match. For example, with a product score of 40, the match will be exact within a 1-2%, error; and at 70, the match will be exact. Homologous molecules are usually identified by selecting those which show product scores between 15 and 40, although lower scores may identify related molecules. The results of northern analysis are reported as a list of libraries in which the transcript encoding TCRLP occurs. Abundance and percent abundance are also reported. Abundance directly reflects the number of times a particular transcript is represented in a cDNA library, and percent abundance is abundance divided by the total number of sequences examined in the cDNA library. V Extension of TCRLP Encoding Polynucleotides The nucleic acid sequence ofthe Incyte Clone 983910 was used to design oligonucleotide primers for extending a partial nucleotide sequence to full length. One primer was synthesized to initiate extension in the antisense direction, and the other was synthesized to extend sequence in the sense direction. Primers were used to facilitate the extension ofthe known sequence "outward" generating amplicons containing new, unknown nucleotide sequence for the region of interest. The initial primers were designed from the cDNA using OLIGO 4.06 (National Biosciences), or another appropriate program, to be about 22 to about 30 nucleotides in length, to have a GC content of 50% or more, and to anneal to the target sequence at temperatures of about 68°to about 72° C Any stretch of nucleotides which would result in hairpin structures and primer-primer dimerizations was avoided. Selected human cDNA libraries (Gibco/BRL) were used to extend the sequence If more than one extension is necessary or desired, additional sets of primers are designed to further extend the known region. High fidelity amplification was obtained by following the instructions for the XL-PCR kit (Perkin Elmer) and thoroughly mixing the enzyme and reaction mix. Beginning with 40 pmol of each primer and the recommended concentrations of all other components of the kit, PCR was performed using the Peltier Thermal Cycler (PTC200; M.J. Research, Watertown, MA) and the following parameters: Step 1 94° C for 1 min (initial denaturation) Step 2 65 ° C for 1 min Step 3 68° C for 6 min Step 4 94° C for 15 sec Step 5 65 ° C for 1 min Step 6 68° C for 7 min Step 7 Repeat step 4-6 for 15 additional cycles Step 8 94° C for 15 sec Step 9 65° C for 1 min Step 10 68° C for 7:15 min Step 11 Repeat step 8-10 for 12 cycles Step 12 72° C for 8 min Step 13 4° C (and holding) A 5-10 μl aliquot of the reaction mixture was analyzed by electrophoresis on a low concentration (about 0.6-0.8%) agarose mini-gel to determine which reactions were successful in extending the sequence. Bands thought to contain the largest products were excised from the gel, purified using QIAQuick™ (QIAGEN Inc., Chatsworth, CA), and trimmed of overhangs using Klenow enzyme to facilitate religation and cloning. After ethanol precipitation, the products were redissolved in 13 μl of ligation buffer, lμl T4-DNA ligase (15 units) and lμl T4 polynucleotide kinase were added, and the mixture was incubated at room temperature for 2-3 hours or overnight at 16° C. Competent E. coli cells (in 40 μl of appropriate media) were transformed with 3 μl of ligation mixture and cultured in 80 μl of SOC medium (Sambrook et al, supra). After incubation for one hour at 37 ° C, the E. coli mixture was plated on Luria Bertani (LB)-agar (Sambrook et al, supra) containing 2x Carb. The following day, several colonies were randomly picked from each plate and cultured in 150 μl of liquid LB/2x Carb medium placed in an individual well of an appropriate, commercially- available, sterile 96-well microtiter plate. The following day, 5 μl of each overnight culture was transferred into a non-sterile 96-well plate and after dilution 1 : 10 with water, 5 μl of each sample was transferred into a PCR array. For PCR amplification, 18 μl of concentrated PCR reaction mix (3.3x) containing 4 units of rTth DNA polymerase, a vector primer, and one or both ofthe gene specific primers used for the extension reaction were added to each well. Amplification was performed using the following conditions: Step 1 94° C for 60 sec Step 2 94° C for 20 sec Step 3 55 ° C for 30 sec Step 4 72° C for 90 sec Step 5 Repeat steps 2-4 for an additional 29 cycles Step 6 72° C for 180 sec Step 7 4° C (and holding) Aliquots ofthe PCR reactions were run on agarose gels together with molecular weight markers. The sizes of the PCR products were compared to the original partial cDNAs, and appropriate clones were selected, ligated into plasmid, and sequenced. In like manner, the nucleotide sequence of SEQ ID NO:2 is used to obtain 5' regulatory sequences using the procedure above, oligonucleotides designed for 5' extension, and an appropriate genomic library. VI Labeling and Use of Individual Hybridization Probes Hybridization probes derived from SEQ ID NO:2 are employed to screen cDNAs, genomic DNAs, or mRNAs. Although the labeling of oligonucleotides, consisting of about 20 base-pairs, is specifically described, essentially the same procedure is used with larger nucleotide fragments. Oligonucleotides are designed using state-of-the-art software such as OLIGO 4.06 (National Biosciences), labeled by combining 50 pmol of each oligomer and 250 μCi of [γ- 32 P] adenosine triphosphate (Amersham) and T4 polynucleotide kinase (DuPont NEN ® , Boston, MA). The labeled oligonucleotides are substantially purified with Sephadex G-25 superfine resin column (Pharmacia & Upjohn). A aliquot containing 10 7 counts per minute ofthe labeled probe is used in a typical membrane-based hybridization analysis of human genomic DNA digested with one ofthe following endonucleases (Ase I, Bgl II, Eco RI, Pst I, Xba 1, or Pvu II; DuPont NEN ® ). The DNA from each digest is fractionated on a 0.7 percent agarose gel and transferred to nylon membranes (Nytran Plus, Schleicher & Schuell, Durham, NH). Hybridization is carried out for 16 hours at 40 °C To remove nonspecific signals, blots are sequentially washed at room temperature under increasingly stringent conditions up to 0.1 x saline sodium citrate and 0.5% sodium dodecyl sulfate. After XOMAT AR™ film (Kodak, Rochester, NY) is exposed to the blots in a Phosphoimager cassette (Molecular Dynamics, Sunnyvale, CA) for several hours, hybridization patterns are compared visually. VII Microarrays To produce oligonucleotides for a microarray, the nucleotide sequence described herein is examined using a computer algorithm which starts at the 3' end ofthe nucleotide sequence. The algorithm identifies oligomers of defined length that are unique to the gene, have a GC content within a range suitable for hybridization, and lack predicted secondary structure that would interfere with hybridization. The algorithm identifies 20 sequence-specific oligonucleotides of 20 nucleotides in length (20-mers). A matched set of oligonucleotides is created in which one nucleotide in the center of each sequence is altered. This process is repeated for each gene in the microarray, and double sets of twenty 20 mers are synthesized and arranged on the surface ofthe silicon chip using a light-directed chemical process (Chee, M. et al, PCT/W095/1 1995, incorporated herein by reference). In the alternative, a chemical coupling procedure and an ink jet device are used to synthesize oligomers on the surface of a substrate (Baldeschweiler, J.D. et al, PCT/W095/25116, incorporated herein by reference). In another alternative, a "gridded" array analogous to a dot (or slot) blot is used to arrange and link cDNA fragments or oligonucleotides to the surface of a substrate using a vacuum system, thermal, UV, mechanical or chemical bonding procedures. An array may be produced by hand or using available materials and machines and contain grids of 8 dots, 24 dots, 96 dots, 384 dots, 1536 dots or 6144 dots. After hybridization, the microarray is washed to remove nonhybridized probes, and a scanner is used to determine the levels and patterns of fluorescence. The scanned images are examined to determine degree of complementarity and the relative abundance of each oligonucleotide sequence on the micro-array. VIII Complementary Polynucleotides Sequence complementary to the TCRLP-encoding sequence, or any part thereof, is used to decrease or inhibit expression of naturally occurring TCRLP. Although use of oligonucleotides comprising from about 15 to about 30 base-pairs is described, essentially the same procedure is used with smaller or larger sequence fragments. Appropriate oligonucleotides 5 are designed using Oligo 4.06 software and the coding sequence of TCRLP, SEQ ID NO: 1. To inhibit transcription, a complementary oligonucleotide is designed from the most unique 5' sequence and used to prevent promoter binding to the coding sequence. To inhibit translation, a complementary oligonucleotide is designed to prevent ribosomal binding to the TCRLP-encoding transcript. 10 IX Expression of TCRLP Expression of TCRLP is accomplished by subcloning the cDNAs into appropriate vectors and transforming the vectors into host cells. In this case, the cloning vector is also used to express TCRLP in E. coli. Upstream ofthe cloning site, this vector contains a promoter for 15 β-galactosidase, followed by sequence containing the amino-terminal Met, and the subsequent seven residues of β-galactosidase. Immediately following these eight residues is a bacteriophage promoter useful for transcription and a linker containing a number of unique restriction sites. Induction of an isolated, transformed bacterial strain with IPTG using standard methods produces a fusion protein which consists ofthe first eight residues of β-galactosidase, about 5 to 20 15 residues of linker, and the full length protein. The signal residues direct the secretion of TCRLP into the bacterial growth media which can be used directly in the following assay for activity. X Demonstration of TCRLP Activity 25 TCRLP activity may be demonstrated by stimulating a TCRLP transformed cell line and assaying the induction of interleukin-2 (IL-2). A mammalian cell line such as COS or Jurket (ATCC) is transfected with eukaryotic expression vectors encoding TCRLP. Eukaryotic expression vectors are commercially available, and the techniques to introduce them into cells are well known to those skilled in the art. The cells are maintained in RPMI media with 10% fetal 30 bovine serum, 100 units/ml penicillin, 100 μg/ml streptomycin sulfate, and 2 mM glutamine, at 37 °C in a humidified 5% CO atmosphere. The transformed cells are incubated for 48-72 hours after transformation under conditions appropriate for the cell line to allow expression and accumulation of TCRLP. After the incubation period the cells are activated by the addition of 2.5 μg/ml phytohemagglutinin (Boehringer Mannheim) to the medium. Samples ofthe medium are analyzed at 24, 48, and 72 hours for the presence of IL-2 by ELISA using anti-IL-2 polyclonal IgG (Santa Cruz Biotechnology, Inc., Santa Cruz, CA). The results are evaluated by comparison with mock-transfected and unstimulated cell controls. XI Production of TCRLP Specific Antibodies TCRLP that is substantially purified using PAGE electrophoresis (Sambrook, supra), or other purification techniques, is used to immunize rabbits and to produce antibodies using standard protocols. The amino acid sequence deduced from SEQ ID NO:2 is analyzed using DNASTAR software (DNASTAR Inc) to determine regions of high immunogenicity and a corresponding oligopeptide is synthesized and used to raise antibodies by means known to those of skill in the art. Selection of appropriate epitopes, such as those near the C-terminus or in hydrophilic regions, is described by Ausubel et al. (supra), and others. Typically, the oligopeptides are 15 residues in length, synthesized using an Applied Biosystems Peptide Synthesizer Model 431 A using fmoc-chemistry, and coupled to keyhole limpet hemocyanin (KLH, Sigma, St. Louis, MO) by reaction with N-maleimidobenzoyl-N- hydroxysuccinimide ester (MBS; Ausubel et al, supra). Rabbits are immunized with the oligopeptide-KLH complex in complete Freund's adjuvant. The resulting antisera are tested for antipeptide activity, for example, by binding the peptide to plastic, blocking with 1% BSA, reacting with rabbit antisera, washing, and reacting with radio iodinated, goat anti-rabbit IgG. XII Purification of Naturally Occurring TCRLP Using Specific Antibodies Naturally occurring or recombinant TCRLP is substantially purified by immunoaffmity chromatography using antibodies specific for TCRLP. An immunoaffmity column is constructed by covalently coupling TCRLP antibody to an activated chromatographic resin, such as CNBr-activated Sepharose (Pharmacia & Upjohn). After the coupling, the resin is blocked and washed according to the manufacturer's instructions. Media containing TCRLP is passed over the immunoaffmity column, and the column is washed under conditions that allow the preferential absorbance of TCRLP (e.g., high ionic strength buffers in the presence of detergent). The column is eluted under conditions that disrupt antibody/TCRLP binding (eg, a buffer of pH 2-3 or a high concentration of a chao trope, such as urea or thiocyanate ion), and TCRLP is collected. XIII Identification of Molecules Which Interact with TCRLP TCRLP or biologically active fragments thereof are labeled with 125 I Bolton-Hunter reagent (Bolton et al (1973) Biochem. J. 133: 529). Candidate molecules previously arrayed in the wells of a multi-well plate are incubated with the labeled TCRLP, washed and any wells with labeled TCRLP complex are assayed. Data obtained using different concentrations of TCRLP are used to calculate values for the number, affinity, and association of TCRLP with the candidate molecules.
