Description: HUMAN PROTEIN KINASES TECHNICAL FIELD The present invention relates to nucleic acid and amino acid sequences of novel human protein kinases and to the use of these sequences in the diagnosis, study, prevention and treatment of disease. BACKGROUND ART Kinases regulate many different cell proliferation, differentiation, and signalling processes by adding phosphate groups to proteins. Uncontrolled signalling has been implicated in a variety of disease conditions including, inflammation, cancer, arteriosclerosis, and psoriasis. Reversible protein phosphorylation is the main strategy for controlling activities of eukaryotic cells. It is estimated that more than 1000 of the 10.000 proteins active in a typical mammalian cell are phosphorylated. The high energy phosphate which drives activation is generally transferred from adenosine triphosphate molecules (ATP) to a particular protein by protein kinases and removed from that protein by protein phosphatases. Phosphorylation occurs in response to extracellular signals (hormones, neurotransmitters. growth and differentiation factors, etc), cell cycle checkpoints, and environmental or nutritional stresses and is roughly analogous to turning on a molecular switch. When the switch goes on. the appropriate protein kinase activates a metabolic enzyme, regulatory protein, receptor, cytoskeletal protein, ion channel or pump, or transcription factor. The kinases comprise the largest known protein group, a superfamily of enzymes with widely varied functions and specificities. They are usually named after their substrate, their regulatory molecules, or some aspect of a mutant phenotype. Almost all kinases contain a similar 250-300 amino acid catalytic domain. The N-terminal domain, which contains subdomains I-IV. generally folds into a two-lobed structure which binds and orients the ATP (or GTP) donor molecule. The larger C terminal lobe, which contains subdomains VI A-XI. binds the protein substrate and carries out the transfer of the gamma phosphate from ATP to the hydroxyl group of a serine, threonine. or tyrosine residue. Subdomain V spans the two lobes. The kinases may be categorized into families by the different amino acid sequences (generally between 5 and 100 residues) located on either side of. or inserted into loops of. the kinase domain. These added amino acid sequences allow the regulation of each kinase as it recognizes and interacts with its target protein. The primary structure of the kinase domains is conserved and can be further subdivided into 1 1 subdomains. Each of the 1 1 subdomains contain specific residues and motifs or patterns of amino acids that are characteristic of that subdomain and are highly conserved (Hardie G and Hanks S ( 1995) The Protein Kinase Facts Books. I and II, Academic Press, San Diego CA). The second messenger dependent protein kinases primarily mediate the effects of second messengers such as cyclic AMP (cAMP) cyclic GMP. inositol triphosphate. phosphatidylinositol. 3,4,5-triphosphate. cyclic ADPribose, arachidonic acid and diacylglycerol. Cyclic-AMP is an intracellular mediator of hormone action in all procaryotic and animal cells that have been studied. Such hormone-induced cellular responses include thyroid hormone secretion, cortisol secretion, progesterone secretion, glycogen breakdown, bone resorption, and regulation of heart rate and force of heart muscle contraction. Cyclic AMP-dependent protein kinase (PKA) is found in all animal cells and is thought to account for the all of the effects of cyclic-AMP in most of these cells. In its inactive state. A-kinase consists of a complex of two catalytic subunits and two regulatory subunits. When each regulatory subunit has bound two molecules of c AMP. the catalytic subunit is activated and can transfer a high energy phosphate from ATP to the serine or threonine of a substrate protein. Altered PKA expression is implicated in a variety of disorders and diseases including; thyroid disorders, diabetes, atherosclerosis, and cardiovascular disease (Isselbacher KJ et al (1994) Harrison's Principles of Internal Medicine, McGraw-Hill, New York City). Protein kinase C (PKC) is a water-soluble. Ca"-dependent kinase. commonly found in brain tissue, which moves to the plasma membrane in the presence of Ca " ions. Approximately half of the known isoforms of PKC are activated initially by diacylglycerol and phosphatidylserine. Prolonged activation of PKC depends on continued production of diacyglycerol molecules which are formed when phospholipases cleave phosphatidylcholine. In nerve cells. PKC phosphorylates ion channels and alters the excitability of the cell membrane. In other cells, activation of PKC increases gene transcription either by triggering a protein kinase cascade which activates a regulatory element or by phosphorylating and deactivating an inhibitor of the regulatory protein. PKC activity has been specifically linked to multi-drug resistance in cancer (O'Brian CA et al (1995) Prog Clin Biol Res 391 : 1 17-120), tumor promotion (O'Brian CA and Ward NE (1989) Cancer Metast Rev 8: 199-214) memory disorders (Saito N. et al (1994) Brain Res 656: 245-256), and auto-immune disease (Ohkusu K et al (1995) Eur J Immunol 25: 3180-3186). A detailed understanding of kinase pathways and signal transduction is beginning to .9- reveal some mechanisms for interceding in the progression of inflammatory illnesses and of uncontrolled cell proliferation. The novel kinases.polynucleotides which encode them, and antibodies to them satisfy a need in the art by providing a plurality of tools for studying signalling cascades in various cells and tissues, diagnosing disease and selecting inhibitors or drugs with the potential to intervene in various disorders or diseases in which altered kinase expression is implicated. DISCLOSURE OF THE INVENTION The present invention is directed to three novel human protein kinases (hereinafter referred to individually as HPK1 , HPK2. and HPK3, and collectively as HPK) characterized as having homology to other protein kinases. Accordingly, the invention features substantially purified HPK, comprising the amino acid sequences of SEQ ID NOs:l . 3. and 5, or fragments thereof and having functional characteristics of protein kinase family members.

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 of the present invention which will be limited only by the appended claims. It must be noted that as used herein an in the appended claims, the singular forms of "a", "and", and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, referrence to "a host cell" includes a plurality of such host cells and referrence to "the antibody" includes reference to one or more antibodies and equivalents thereof known to those skilled in the arts, and so forth. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described herein can be used in the practice of testing of the 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 described in the publications which might be used in connection with the presently described invention. The publications discussed herein are provided solely for their disclosure pprior sto the filing date of the present application. Nothing herein is to be construed as an .admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention. Definitions "Nucleic acid sequence " as used herein refers to an oligonucleotide, nucleotide or polynucleotide, and fragments or portions thereof, and to DNA or RNΛ of genomic or synthetic origin which may be single- or double-stranded, and represent the sense or antisense strand. Similarly, amino acid sequence as used herein refers to protein or peptide sequence. "Consensus" as used herein may refer to a nucleic sequence 1 ) which has been resequenced to resolve uncalled bases, 2) which has been extended using XL-PCR (Perkin Elmer) in the 5' or the 3' direction and resequenced, 3) which has been assembled from overlapping sequences of more than one Incyte clone GCG Fragment Assembly System. (GCG. Madison WI), or 4) which has been both extended and assembled. "Peptide nucleic acid" as used herein refers to a molecule which comprises an oligomer to which an amino acid residue, such as lysine, and an amino group have been added. These small molecules, also designated anti-gene agents, stop transcript elongation by binding to their complementary (template) strand of nucleic acid (Nielsen PE et al (1993) Anticancer Drug Des 8:53-63). As used herein, HPK refers to the amino acid sequence of substantially purified HPK from any source whether natural, synthetic, semi-synthetic or recombinant. A "variant" of HPK is defined as an amino acid sequence that is different by one or more amino acid substitutions. The variant may have "conservative" changes, wherein a substituted amino acid has similar structural or chemical properties, eg, replacement of leucine with isoleucine. More rarely, a variant may have "nonconservative " changes, eg, replacement of a glycine with a tryptophan. Similar minor variations may also include amino acid deletions or insertions, or both. Guidance in determining which and how many 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. A "deletion" is defined as a change in either nucleotide or amino acid sequence in which one or more nucleotides or amino acid residues, respectively, are absent. An "insertion" or "addition" is that change in a nucleotide or amino acid sequence which has resulted in the addition of one or more nucleotides or amino acid residues, respectively, as compared to the naturally occurring HPK. A "substitution" results from the replacement of one or more nucleotides or amino acids by different nucleotides or amino acids, respectively. The term "biologically active" refers to a HPK having structural, regulatory or biochemical functions of the naturally occurring HPK. Likewise, "immunologically active" defines the capability of the natural, recombinant or synthetic HPK, or any oligopeptide thereof, to induce a specific immune response in appropriate animals or cells and to bind with specific antibodies. The term "derivative" as used herein refers to the chemical modification of a nucleic acid sequence encoding HPK or the encoded HPK. Illustrative of such modifications would be replacement of hydrogen by an alkyl, acyl, or amino group. A nucleic acid derivative would encode a polypeptide which retains essential biological characteristics of natural HPK. As used herein, the term "substantially purified" refers to molecules, either 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. "Stringency" typically occurs in a range from about Tm-5°C (5°C below the Tm of the probe)to about 20°C to 25°C below Tm. As will be understood by those of skill in the art. a stringency hybridization can be used to identify or detect identical polynucleotide sequences or to identify or detect similar or related polynucleotide sequences. The term "hybridization" as used herein shall include "any process by which a strand of nucleic acid joins with a complementary strand through base pairing" (Coombs J ( 1994) Dictionary of Biotechnology. Stockton Press, New York NY). Amplification as carried out in the polymerase chain reaction technologies is described in Dieffenbach CW and GS Dveksler ( 1995. PCR Primer, a Laboratory Manual, Cold Spring Harbor Press. Plainview NY). Description The present invention relates to novel human protein kinases, HPK. initially identified among the partial cDNAs from a brain hippocampus library (HIPONOTOl; HPK-1), a peripheral blood mononuclear cell library (TMLR3DT01 ; HPK-2) and a macrophage cell library (MPHGN0T03; HPK-3) and to the use of the nucleic acid and amino acid sequences disclosed herein in the study, diagnosis, prevention and treatment of disease. In addition to the above mentioned sources, northern analysis indicates that nucleic acid encoding a portion of HPK-1 was also found in cDNA libraries from neural tissue (multiple sclerosis) and brain tumor. Nucleic acid encoding portions of HPK-2 was found in infant brain. epilepsy (brain) and various tumor tissues (penis carcinoma, bladder carcinoma, and thyroid adenoma). Nucleic acid encoding portions of HPK-3 was found in multiple sclerosis, Alzheimers (brain), osteoarthritic knee tissue, and in tumors of the breast and lung. The present invention also encompasses HPK variants. A preferred HPK variant is one having at least 80% amino acid sequence similarity to the HPK amino acid sequences (SEQ ID NO:l. 3, or 5), a more preferred HPK variant is one having at least 90% amino acid sequence similarity to SEQ ID NO:l. 3. or 5, and a most preferred HPK variant is one having at least 95% amino acid sequence similarity to SEQ ID NO: 1 , 3, or 5. The HPK Coding Sequences Nucleic acid encoding a portion of HPK-1 was first identified in the cDNA, Incyte Clone 240142, through a computer-generated search for amino acid sequence alignments. Similarly, nucleic acids encoding a portion of HPK-2 and HPK-3 were first identified in Incyte Clones 391602 and 477245, respectively. The nucleic acid sequences. SEQ ID NO:2, 4, and 6; disclosed herein encode the amino acid sequences, SEQ ID NO: l . 3, and 5. respectively, disclosed hereinafter as HPK. The present invention is based, in part, on the chemical and structural homology among HPK-1, -2, and -3. and various known protein kinases, and to various amino acid sequence motifs within these proteins that are characteristic of the catalytic domains of protein kinases (Hardie G and Hanks S (1995), supra). Referring to Figures 4A, 4B. and 4C. the sequence GXGXXGXV characteristic of subdomain I in protein kinases is found in HPK-2 beginning at G 7 and in the corresponding residues for HPK-3. GI 1117791. and GI 294637. The conserved lysine residue in subdomain II located at K„ for HPK-2 is repeated for HPK-3. GI 1 117791, and GI 294637. The sequence HRDIKXXN found in subdomain VI B of many protein kinases is found in HPK-1(H, 0 ), HPK-2. HPK-3. GI 1082115 and GI 1 117791. Finally, the triplet sequence DFG in subdomain VII is found in HPK-3 (G 242 ), GI 1 1 17791 , and GI 294637. and the triplet sequence APE (subdomain VIII) is found in HPK-2 (A 2gJ ), HPK-3, GI 1 1 17791 , and GI 294637. Thus each of the protein kinases HPK-1. -2, and -3 bear sequence patterns characteristic of protein kinases. but are distinct from one another in overall sequence. HPK-1 bears 70% sequence identity to a protein kinase from the nematode. C. elegans; GI 10821 15 (Wilson. R et al (1994) Nature 368: 32-38). GI 10821 15 has been characterized as a member of the cyclic-AMP dependent PKA family. HPK-2 bears closest identity (42%)to a human protein kinase; GI 1 1 17791 (Creasy. CL and Chernoff. J ( 1995) J. Biol Chem 270: 21695-21700). GI 1 1 17791 is- characterized as being similar to other members of the mitogen-activated protein kinase (MAPK) family but is most likely involved in an as yet unidentified signal transduction pathway. HPK-3 has approximately 96% identity to a protein kinase from rat; GI 294637 (Webster, M.K. et al (1993) Mol. Cell Biol. 13: 2031-2040). GI 294637 is transcriptionally regulated by glucocorticoid hormones and bears sequence homology to protein kinases of both the PKA and PKC families. HPK-1 is encoded by SEQ ID NO:2 and is derived from the extension and assembly of the following partial cDNAs(library), Incyte Clones 67192(HUVESTB01 ); 240142. 243638. and 298165(HIPONOT01); 449634(TLYMNOT02); 461400(KERANOT01); 73913KPANCNOT04); and (12143028?). HPK-2 is encoded by SEQ ID NO:4 and is derived from the extension and assembly of the following partial cDNAs. Incyte Clones 1394374. 1395924, 1392440, 1394764. 1393587. and 1439946(THYRNOT03; 487890(HNT2AGT01); 737620(TONSNOT01); 391602(TMLR3DT01); 373301 (LUNGNOT02); 1291632(PGANNOT03); 550890(BEPINOT01 ); 1314539(BLADTUT02); 647351(BRSTTUT02); 917302(BRSTNOT04), 541 1 17(LNODNOT02); 235796(SINTNOT02); 827973(PROSNOT06); 36252(HUVENOB01); 1339623(COLNTUT03); 719820 and 365833(SYNORAT01); 32632(THP1NOB01); 888061(PANCNOT05); 1262882(SYNORAT05); 975808(MUSCNOT02); 275375(TESTNOT03); 1433039 and 1425069(BEPINON01 );and 94156(PITUNOT01 ). HPK-3 is encoded by SEQ ID NO:6 and is derived from the extension and assembly of the following partial cDNAs, Incyte Clones 477245 and 445652(MPHGNOT03); 386314(THYMNOT02); 1219404(NEUTGMT01 ); 478857(MMLR2DT01); 1239468(LU GTUT02); 603976(BRSTTUT01 ; and 565613(NEUTLPT01). It will be appreciated by those skilled in the art that as a result of the degeneracy of the genetic code, a multitude of HPK-encoding nucleotide sequences, some bearing minimal homology to the nucleotide sequences of any known and naturally occurring gene may be produced. 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 HPK. and all such variations are to be considered as being specifically disclosed. Although nucleotide sequences which encode HPK and its variants are preferably capable of hybridizing to the nucleotide sequence of the naturally occurring HPK under appropriately selected conditions of stringency, it may be advantageous to produce nucleotide sequences encoding HPK 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 expression host in accordance with the frequency with which particular codons are utilized by the host. Other reasons for substantially altering the nucleotide sequence encoding HPK 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. It is now possible to produce a DNA sequence, or portions thereof, encoding any of the claimed HPK and derivatives, entirely by synthetic chemistry, after which the synthetic gene may be inserted into any of the many available DNA vectors and cell systems using reagents that are well known in the art at the time of the filing of this application. Moreover, synthetic chemistry may be used to introduce mutations into a HPK sequence or any portion thereof. Also included within the scope of the present invention are polynucleotide sequences that are capable of hybridizing to the nucleotide sequence of Figures 1A. IB, 1C and ID under various conditions of stringency. Hybridization conditions are based on the melting temperature (Tm) of the nucleic acid binding complex or probe, as taught in Berger and Kimmel (1987. Guide to Molecular Cloning Techniques. Methods in Enzymology. Vol 152, Academic Press. San Diego CA) incorporated herein by reference, and may be used at a defined stringency. Altered nucleic acid sequences encoding HPK which may be used in accordance with the invention include deletions, insertions or substitutions of different nucleotides resulting in a polynucleotide that encodes the same or a functionally equivalent HPK. The protein may also show deletions, insertions or substitutions of amino acid residues which produce a silent change and result in a functionally equivalent HPK. Deliberate amino acid substitutions may be made on the basis of similarity in polarity, charge, solubility, hydrophobicity. hydrophilicity, and/or the amphipathic nature of the residues as long as the biological activity of HPK is retained. For example, negatively charged amino acids include aspartic acid and glutamic acid; positively charged amino acids include lysine and arginine; and amino acids with uncharged polar head groups having similar hydrophilicity values include leucine. isoleucine, valine; glycine. alanine: asparagine. glutamine; serine. threonine phenylalanine. and tyrosine. Included within the scope of the present invention are alleles of HPK encoding sequences. As used herein, an "allele" or "allelic sequence" is an alternative form of an HPK encoding sequence. Alleles result from a mutation, for example, a change in the nucleic acid sequence, and generally produce altered RNAs or polypeptides whose structure or function may or may not be altered. Any given gene may have, one or many allelic forms, or none at all. Common mutational changes which give rise to alleles are generally ascribed to natural deletions, additions or substitutions of amino acids. Each of these types of changes may occur alone, or in combination with the others, one or more times in a given sequence. Methods for DNA sequencing which are well known in the art may be used and these methods may employ such enzymes as the Klenow fragment of DNA polymerase I. Sequenase® (US Biochemical Corp, Cleveland OH)), Taq polymerase (Perkin Elmer, Norwalk CT), thermostable T7 polymerase (Amersham, Chicago IL), or combinations of recombinant polymerases and proofreading exonucleases such as 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 377 DNA sequencers (Perkin Elmer). Extending the Polynucleotide Sequence The polynucleotide sequence encoding HPK may be extended utilizing partial nucleotide sequence and various methods known in the art to detect upstream sequences such as promoters and regulatory elements. For example, one may use "restriction-site" polymerase chain reaction (PCR) as a direct method which uses universal primers to retrieve an unknown sequence adjacent to a known locus (Gobinda et al (1993) PCR Methods Applic 2:318-22). In particular, the genomic DNA is amplified in the presence of primer to a linker sequence and a primer specific to the known region. The amplified sequences are 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 can 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 OLIGO® 4.06 Primer Analysis Software (1992; 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 (Lagerstrom M et al ( 1991) PCR Methods Applic 1 : 1 1 1-19) which involves PCR amplification of DNA fragments adjacent to a known sequence in human and yeast artificial chromosome DNA. Capture PCR involves multiple restriction enzyme digestions and ligations to place an engineered double-stranded sequence into an unknown portion of the DNA molecule before PCR. Another method which may be used to retrieve unknown sequences is that of (Parker JD et al (1991 : Nucleic Acids Res 19:3055-60). Additionally, one can use PCR. nested primers and PromoterFinder libraries to walk in genomic DNA (PromoterFinder™ Clontech. Palo Alto CA). This process avoids the need to screen libraries and is useful in finding intron/exon junctions. Preferred libraries for screening for full length cDNAs are those that have been size-selected to include larger cDNAs. Also, random primed libraries are preferred in that they will contain more sequences which contain the 5' and upstream regions of genes. A randomly primed library may be particularly useful if an oligo d(T) library does not yield a full-length cDNA. Genomic libraries are useful for extension into the 5' nontranslated regulatory region. Capillary electrophoresis may be used to analyze the size or confirm the nucleotide sequence of sequencing or PCR products. Systems for rapid sequencing are available from Perkin Elmer. Beckman Instruments (Fullerton CA), and other companies. Capillary sequencing may employ flowable polymers for electrophoretic separation, four different fluorescent dyes (one for each nucleotide) which are laser activated, and detection of the emitted wavelengths by a charge coupled devise camera. Output/light intensity is converted to an electrical signal using appropriate software (eg. Genotyper™ and Sequence Navigator™ from Perkin Elmer) and the entire process from loading of samples to computer analysis and electronic data display is computer controlled. Capillary electrophoresis is particularly suited to the sequencing of small pieces of DNA which might be present in limited amounts in a particular sample. The reproducible sequencing of up to 350 bp of Ml 3 phage DNA in 30 min has been reported (Ruiz-Martinez MC et al (1993) Anal Chem 65:2851-8). Expression of the Nucleotide and Protein Sequences In accordance with the present invention, polynucleotide sequences which encode HPK. fragments of the polypeptide. fusion proteins or functional equivalents thereof may be used in recombinant DNA molecules that direct the expression of HPK in appropriate host cells. Due to the inherent degeneracy of the genetic code, other DNA sequences which encode substantially the same or a functionally equivalent amino acid sequence, may be used to clone and express HPK. As will be understood by those of skill in the art. it may be advantageous to produce HPK-encoding nucleotide sequences possessing non-naturally occurring codons. Codons preferred by a particular prokaryotic or eukaryotic host can be selected, for example, to increase the rate of HPK encoding sequences expression or to produce recombinant RNA transcripts having desirable properties, such as a longer half-life, than transcripts produced from naturally occurring sequence (Murray E et al (1989) Nuc Acids Res 17:477-508). The nucleotide sequences of the present invention can be engineered in order to alter HPK 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. For example, mutations may be introduced using techniques which are well known in the art. For example, site-directed mutagenesis may be used to insert new restriction sites, alter glycosylation patterns, change codon preference, produce splice variants, and so forth. 5 In another embodiment of the invention, a natural, modified or recombinant sequence encoding HPK may be ligated to a heterologous sequence to encode a fusion protein. For example, for screening of peptide libraries for inhibitors of HPK activity, it may be useful to encode a chimeric HPK protein that is recognized by a commercially available antibody. A fusion protein may also be engineered to contain a cleavage site located between a HPK sequence 10 and the heterologous protein sequence, so that the HPK may be cleaved and substantially purified away from the heterologous moiety. In an alternate embodiment of the invention, the sequence encoding HPK may be synthesized, whole or in part, using chemical methods well known in the art (see Caruthers MH et al (1980) Nuc Acids Res Symp Ser 215-23. Horn T et al (1980) Nuc Acids Res Symp Ser 15 225-32. etc). Alternatively, the proteins may be produced using chemical methods to synthesize amino acid sequences, whole or in part. For example, peptide synthesis can be performed using various solid-phase techniques (Roberge JY et al (1995) Science 269:202-204) and automated synthesis may be achieved, for example, using the ABI 431 A Peptide Synthesizer (Perkin Elmer) in accordance with the instructions provided by the manufacturer. 0 The newly synthesized peptide can be substantially purified by preparative high performance liquid chromatography (eg. Creighton ( 1983) Proteins. Structures and Molecular Principles. WH Freeman and Co. New York NY). The composition of the synthetic peptides may be confirmed by amino acid analysis or sequencing (eg, the Edman degradation procedure; Creighton, supra). Additionally the amino acid sequence of HPK. or any part thereof, may be 25 altered during direct synthesis and/or combined using chemical methods with sequences from other proteins, or any part thereof, to produce a variant polypeptide. Expression Systems In order to express a biologically active HPK, the nucleotide sequence encoding HPK or its functional equivalent, is inserted into an appropriate expression vector, ie. a vector which 30 contains the necessary elements for the transcription and translation of the inserted coding sequence. Methods which are well known to those skilled in the art can be used to construct expression vectors containing a HPK coding sequence and appropriate transcriptional or translational controls. These methods include in vitro recombinant DNA techniques, synthetic techniques and in vivo recombination or genetic recombination. Such techniques are described in Sambrook et al (1989) Molecular Cloning. Δ Laboratory Manual. Cold Spring Harbor Press. Plainview NY and Ausubel FM 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 a HPK coding sequence. 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 (eg, baculovirus); plant cell systems transfected with virus expression vectors (eg, cauliflower mosaic virus. CaMV: tobacco mosaic virus. TMV) or transformed with bacterial expression vectors (eg, Ti or pBR322 plasmid); or animal cell systems. The "control elements" or "regulatory sequences" of these systems may vary in their strength and specificities and are those nontranslated regions of the vector, enhancers, promoters, and 3' untranslated regions, which interact with host cellular proteins to carry out transcription and translation. Depending on the vector system and host utilized, any number of suitable transcription and translation elements, including constitutive and inducible promoters, may be used. For example, when cloning in bacterial systems, inducible promoters such as the hybrid lacZ promoter of the Bluescript® phagemid (Stratagene. LaJolla CA) or pSportl (Gibco BRL) and ptrp-lac hybrids and the like may be used. The baculovirus polyhedrin promoter may be used in insect cells. Promoters or enhancers derived from the genomes of plant cells (eg. heat shock. RUBISCO; and storage protein genes) or from plant viruses (eg, viral promoters or leader sequences) may be cloned into the vector. In mammalian cell systems, promoters from the mammalian genes or from mammalian viruses are most appropriate. If it is necessary to generate a cell line that contains multiple copies of HPK encoding sequences, vectors based on SV40 or EBV may be used with an appropriate selectable marker. In bacterial systems, a number of expression vectors may be selected depending upon the use intended for HPK. For example, when large quantities of HPK are needed for the induction of antibodies, vectors which direct high level expression of fusion proteins that are readily purified may be desirable. Such vectors include, but are not limited to. the multifunctional £. coli cloning and expression vectors such as Bluescript® (Stratagene). in which the HPK encoding sequences may be ligated into the vector in frame with sequences for the amino-terminal Met and the subsequent 7 residues of β-galactosidase so that a hybrid protein is produced; pIN vectors (Van Heeke & 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 in such systems may be designed to include heparin. 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. Saccharomyces cerevisiae. a number of vectors containing constitutive or inducible promoters such as alpha factor, alcohol oxidase and PGH may be used. General methodology may be found in Ausubel et al (supra) and Grant et al (1987) Methods in Enzymology 153:516-544. In cases where plant expression vectors are used, the expression of a sequence encoding HPK may be driven by any of a number of promoters. For example, viral promoters such as the 35S and 19S promoters of CaMV (Brisson et al (1984) Nature 310:51 1-514) may be used alone or in combination with the omega leader sequence from TMV (Takamatsu et al (1987) EMBO J 6:307-311 ). Alternatively, plant promoters such as the small subunit of RUBISCO (Coruzzi et al (1984) EMBO J 3:1671-1680; Brogue et al (1984) Science 224:838-843); or heat shock promoters (Winter J and Sinibaldi RM (1991) Results Probl Cell Differ 17:85-105) may be used. These constructs can be introduced into plant cells by direct DNA transformation or pathogen-mediated transfection. For reviews of-such techniques, see Hobbs S or Murry LE in McGraw Hill Yearbook of Science and Technology ( 1992) McGraw Hill New York NY, pp 191 -196 or Weissbach and Weissbach (1988) Methods for Plant Molecular Biology. Academic Press, New York NY, pp 421 -463. An alternative expression system which could be used to express HPK encoding sequences is an insect system. In one such system, Autographa californica nuclear poiyhedrosis virus (AcNPV) is used as a vector to express foreign genes in Spodoptera frugiperda cells or in Trichoplusia larvae. The HPK encoding sequences may be cloned into a nonessential region of the virus, such as the polyhedrin gene, and placed under control of the polyhedrin promoter. Successful insertion of HPK encoding sequences will render the polyhedrin gene inactive and produce recombinant virus lacking coat protein coat. The recombinant viruses may then be used to infect S. frugiperda cells or Trichoplusia larvae in which HPK is expressed (Smith et al (1983) J Virol 46:584; Engelhard EK et al (1994) Proc Nat Acad Sci 91 :3224-7). 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, an HPK encoding sequence may be ligated into an adenovirus transcription/translation complex consisting of the late promoter and tripartite leader sequence. Insertion in a nonessential El or E3 region of the viral genome will result in a viable virus capable of expressing HPK in infected host cells (Logan and Shenk (1984) Proc Natl Acad Sci 81 :3655-59). In addition, transcription enhancers, such as the rous sarcoma virus (RSV) enhancer, may be used to increase expression in mammalian host cells. Specific initiation signals may also be required for efficient translation of an HPK encoding sequence. These signals include the ATG initiation codon and adjacent sequences. In cases where an HPK encoding sequence, its initiation codon and upstream sequences are inserted into the appropriate expression vector, no additional translational control signals may be needed. However, in cases where only coding sequence, or a portion thereof, is inserted, exogenous transcriptional control signals including the ATG initiation codon should be provided. Furthermore, the initiation codon must be in the correct reading frame to ensure transcription of the entire insert. Exogenous transcriptional elements and initiation codons can be of various origins, both natural and synthetic. The efficiency of expression may be enhanced by the inclusion of enhancers appropriate to the cell system in use (Scharf D et al (1994) Results Probl Cell Differ 20: 125-62: Bittner et al (1987) Methods in Enzymol 153:516-544). 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 of the polypeptide include, but are not limited to. acetylation. carboxylation, glycosylation, phosphorylation. lipidation and acylation. Post-translational processing which cleaves a "prepro" form of the protein may also be important for correct insertion, folding and/or function. Different host cells such as CHO. HeLa. MDCK, 293. WI38, etc have specific cellular machinery and characteristic mechanisms for such post-translational activities and may be chosen to ensure the correct modification and processing of the introduced, foreign protein. For long-term, high-yield production of recombinant proteins, stable expression is preferred. For example, cell lines which stably express HPK encoding sequences may be transformed using expression vectors which contain viral origins of replication or endogenous expression elements and a selectable marker gene. 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 of the selectable marker is to confer resistance to selection, and its presence allows growth and recovery of cells which successfully express the introduced sequences. Resistant clumps of stably transformed cells can 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 and adenine phosphoribosyltransferase genes which can be employed in tk- or aprt- cells, respectively (Wigler M et al (1977) Cell 1 1 :223-32; Lowy I et al (1980) Cell 22:817-23). Also, antimetabolite. antibiotic or herbicide resistance can be used as the basis for selection; for example, dhfr which confers resistance to methotrexate; npt. which confers resistance to the aminoglycosides neomycin and G-418 and als or pat, which confer resistance to chlorsulfuron and phosphinotricin acetyltransferase. respectively (Wigler M et al (1980) Proc Natl Acad Sci 77:3567-70; Colbere-Garapin F et al (1981 ) J Mol Biol 150: 1 -14; Murry, supra). Additional selectable genes may be used, 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 SC and RC Mulligan (1988) Proc Natl Acad Sci 85:8047-51 ). Visible markers such as anthocyanins. β glucuronidase and its substrate, GUS, and luciferase and its substrate, luciferin, may be 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 C A et al ( 1995 ) Methods Mol Biol 55 : 121 - 131 ). Identification of Transformants Containing the Polynucleotide Sequence Although the presence/absence of marker gene expression suggests that the gene of interest is also present, its presence and expression should be confirmed. For example, if the HPK encoding sequence is inserted within a marker gene sequence, recombinant cells containing HPK encoding sequences can be identified by the absence of marker gene function. Alternatively, a marker gene can be placed in tandem with an HPK sequence under the control of a single promoter. Expression of the marker gene in response to induction or selection usually indicates expression of the tandem HPK encoding sequence as well. Alternatively, host cells which contain the HPK encoding sequence and express HPK 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 hybridization and protein bioassay or immunoassay techniques which include membrane, solution, or chip based technologies for the detection and/or quantification of the nucleic acid or protein. The presence of the polynucleotide sequence encoding HPK can be detected by DNA-DNA or DNA-RNA hybridization or amplification using probes, portions or fragments of HPK encoding sequences. Nucleic acid amplification based assays involve the use of oligonucleotides or oligomers based on the sequence encoding HPK to detect transformants containing HPK encoding sequences in DNA or RNA. As used herein "oligonucleotides" or "oligomers" refer to a nucleic acid sequence of at least about 10 nucleotides and as many as about 60 nucleotides. preferably about 15 to 30 nucleotides. and more preferably about 20-25 nucleotides which can be used as a probe or amplimer. A variety of protocols for detecting and measuring the expression of HPK, using either polyclonal or monoclonal antibodies specific for the protein are well known in the art. Examples include enzyme-linked immunosorbent assay (ELISA). radioimmunoassay (RIA) and fluorescent activated cell sorting (FACS). A two-site, monoclonal-based immunoassay utilizing monoclonal antibodies reactive to two non-interfering epitopes on HPK 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 DE et al (1983. J Exp Med 158:1211). A wide variety of labels and conjugation techniques are known by those skilled in the art and can be used in various nucleic acid and amino acid assays. Means for producing labeled hybridization or PCR probes for detecting sequences related to HPK encoding sequences include oligolabeling. nick translation, end-labeling or PCR amplification using a labeled nucleotide. Alternatively, the HPK encoding sequence, or any portion of it, 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. A number of commereccial kits or protocols for these procedures may be obtained from companies such as Pharmacia Biotech (Piscataway NJ). Promega (Madison WI), and US Biochemical Corp (Cleveland OH. Suitable reporter molecules or labels include those radionuclides, enzymes, fluorescent, chemiluminescent. or chromogenic agents as well as substrates, cofactors. inhibitors, magnetic particles and the like. Protocols for using these labels are widely available in the art. One may also produce recombinant immunoglobulins by methods provided in the art. Purification of HPK Host cells transformed with a nucleotide sequence encoding HPK may be cultured under conditions suitable for the expression and recovery of the encoded protein from cell culture. The protein produced by a recombinant 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 encoding HPK can be designed with signal sequences which direct secretion of HPK through a prokaryotic or eukaryotic cell membrane. Other recombinant constructions may be used to join HPK encoding sequences to a nucleotide sequence encoding a polypeptide domain which will facilitate purification of soluble proteins as described in (Kroll DJ et al (1993) DNA Cell Biol 12:441 -53). HPK may also be expressed as a recombinant protein with one or more additional polypeptide domains added to facilitate protein purification. 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 a cleavable linker sequences such as Factor XA or enterokinase (Invitrogen, San Diego CA) between the purification domain and HPK is useful to facilitate purification. One such expression vector which provides for expression of a fusion protein comprising an HPK contains nucleic acid encoding 6 histidine residues followed by thioredoxin and an enterokinase cleavage site. The histidine residues facilitate purification on IMIAC (immobilized metal ion affinity chromotography as described in Porath et al (1992) Protein Expression and Purification 3: 263-281 ) while the enterokinase cleavage site provides a means for purifying the neuronatin from the fusion protein. In addition to recombinant production, fragments of HPK may be produced by direct peptide synthesis using solid-phase techniques (cf Stewart et al ( 1969) Solid-Phase Peptide Synthesis. WH Freeman Co, San Francisco; Merrifield J (1963) J Am Chem Soc 85:2149-2154). in vitro 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, Foster City CA) in accordance with the instructions provided by the manufacturer. Various fragments of HPK may be chemically synthesized separately and combined using chemical methods to produce the full length molecule. Therapeutic and Diagnostic Uses of HPK Protein The rationale for the use of nucleotide and polypeptide sequences disclosed herein is based in part on the chemical and structural homology among the novel HPK and known protein kinases from C. elegans (GI 10821 15) , rat (GI 294637) and man (GI 11 17791 ) (Wilson et al, supra; Webster et al, supra; Creasy et al. supra). Because of the widespread roles for protein kinases in cell signalling processes in various cells and tissues, altered HPK expression may be implicated in a variety of disorders and diseases. HPK-1 , by virtue of its occurrence in hippocampus, may be involved in memory and learning, and associated with disorders such as Alzheimers disease. Therefore, increasing HPK-1 activity through gene therapy using sequences encoding HPK-1 or by administering agonists of HPK-1 may be useful to reverse memory loss due to Alzheimers. HPK-2 was identified in lymphocytes and associated with a variety of tumor tissues as well as with rheumatoid arthritis. HPK-2 may function in tumor promotion and may therefore provide a target for suppression by antisense molecules of sequences encoding HPK-2 or antagonists of HPK-2 activity as a cancer treatment strategy. Likewise. HPK-2 activity may promote the inflammatory response in arthritis conditions and again provide a target for suppression by antisense molecules of sequences encoding HPK-2 or antagonists of HPK-2 activity. HPK-3 is derived from macrophages which suggests possible involvement in immune response or inflamation. The significant homology between HPK-3 and a glucocorticoid- regulated rat protein kinase. GI 294637. suggests that HPK-3 may be similarly regulated. HPK-3 expression may therefore be involved in the anti-inflammatory and immunosuppressive effects of glucocorticoid treatment for such conditions as asthma, multiple sclerosis, rheumatoid arthritis, as well as for certain cancers such as lymphocytic leukemias and ly phomas. Thus, increasing HPK-3 expression through gene therapy or through administration of agonists of HPK-3 may augument or provide an alternative to glucocorticoid treatment for these conditions. HPK and/or a cell line that expresses HPK may be used to evaluate, screen and identify compounds, synthetic drugs, antibodies, peptides or other molecules that modulate the activity of HPK and may therefore be useful in the treatment of disease conditions associated with expression of HPK. HPK Antibodies HPK-specific antibodies may be useful for the diagnosis of conditions and diseases associated with expression of HPK. 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.such as. those which inhibit dimer formation, are especially preferred for diagnostics and therapeutics. For the production of antibodies, various hosts including goats, rabbits, rats, mice, etc may be immunized by injection with HPK or any portion, fragment or oligopeptide which retains 5 immunogenic properties. It is not necessary that the protein fragment or oligopeptide used for antibody induction have a functional biological activity, however.it must be antigenic. Peptides used to induce specific antibodies may have an amino acid sequence consisting of at least five amino acids, preferably at least 10 amino acids. Preferably they should mimic a portion of the amino acid sequence of the natural protein and may contain the entire amino acid sequence of a 10 small, naturally occurring molecule. Short stretches of HPK amino acids may be fused with those of another protein such as keyhole limpet hemocyanin and antibody produced against the chimeric molecule. Procedures well known in the art can be used for the production of antibodies to HPK. Depending on the host species, various adjuvants may be used to increase immunological 15 response. Such adjuvants include but are not limited to Freund's. mineral gels such as aluminum hydroxide, and surface active substances such as iysolecithin, pluronic polyols, polyanions. peptides, oil emulsions, keyhole limpet hemocyanin. and dinitrophenol. BCG (bacilli Calmette-Guerin) and Corynebacterium parvum are potentially useful human adjuvants. Monoclonal antibodies to HPK may be prepared using any technique which provides for 20 the production of antibody molecules by continuous cell lines in culture. These include but are not limited to the hybridoma technique originally described by Koehler and Milstein (1975 Nature 256:495-497), the human B-cell hybridoma technique (Kosbor et al ( 1983) Immunol Today 4:72; Cote et al ( 1983) Proc Natl Acad Sci 80:2026-2030) and the EBV-hybridoma technique (Cole et al ( 1985) Monoclonal Antibodies and Cancer Therapy. Alan R Liss Inc. New 25 York NY. pp 77-96). 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 et al (1984) Proc Natl Acad Sci 81 :6851 -6855: Neuberger et al (1984) Nature 312:604-608; Takeda et al (1985) Nature 30 314:452-454). Alternatively, techniques described for the production of single chain antibodies (US Patent No. 4.946.778) can be adapted to produce HPK-specific single chain antibodies Antibodies may also be produced by inducing in vivo production in the lymphocyte population or by screening recombinant immunoglobulin libraries or panels of highly specific binding reagents as disclosed in Orlandi et al (1989. Proc Natl Acad Sci 86:3833-3837), and Winter G and Milstein C (1991 : Nature 349:293-299). Antibody fragments which contain specific binding sites for HPK 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 of the antibody molecule and the Fab fragments which can be generated by reducing the disulfide bridges of the 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 WD et al.(1989) Science 256:1275-1281). A variety of 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 formation of complexes between HPK and its specific antibody and the measurement of complex formation. A two-site, monoclonal-based immunoassay utilizing monoclonal antibodies reactive to two non-interfering epitopes on a specific HPK protein is preferred, but a competitive binding assay may also be employed. These assays are described in Maddox DE et al (1983. J Exp Med 158:121 1). Diagnostic Assays Using HPK Specific Antibodies Particular HPK antibodies may be used for the diagnosis of conditions or diseases characterized by expression of HPK or in assays to monitor patients being treated with HPK agonists or antagonists. Diagnostic assays for HPK include methods utilizing the antibody and a label to detect HPK in human body fluids or extracts of cells or tissues. The polypeptides and antibodies of the present invention may be used vith or without modification. Frequently, the polypeptides and antibodies will be labeled by joining them, either covalently or noncovalently, with a reporter molecule. A wide variety of reporter molecules are known, several of which are described above. A variety of protocols for measuring HPK. using either polyclonal or monoclonal antibodies specific for the respective protein are known in the art. Examples include enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA) and fluorescent activated cell sorting (FACS). A two-site, monoclonal-based immunoassay utilizing monoclonal antibodies reactive to two non-interfering epitopes on HPK is preferred, but a competitive binding assay may be employed. These assays are described, among other places, in Maddox. DE et al (1983, J Exp Med 158:1211). In order to provide a basis for diagnosis, normal or standard values for HPK expression must be established. This is accomplished by combining body fluids or cell extracts taken from normal subjects, either animal or human, with antibody to HPK under conditions suitable for complex formation which are well known in the art. The amount of standard complex formation may be quantified by comparing various artificial membranes containing known quantities of HPK with both control and disease samples from biopsied tissues. Then, standard values obtained from normal samples may be compared with values obtained from samples from subjects symptomatic of the disease. Deviation between standard and subject values establishes the presence of a disease state. Drug Screening HPK. its catalytic or immunogenic fragments or oligopeptides thereof, can be used for screening therapeutic compounds in any of a variety of drug screening techniques. The fragment employed in such a test may be free in solution, affixed to a solid support, borne on a cell surface, or located intracellularly. The formation of binding complexes, between HPK 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 HPK (WO Application 84/03564, incorporated herein by reference). In summary, large numbers of different small peptide test compounds are synthesized on a solid substrate, such as plastic pins or some other surface. The peptide test compounds are reacted with fragments of HPK and washed. Bound HPK is then detected by methods well known in the art. Substantially purified HPK 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. This invention also contemplates the use of competitive drug screening assays in which neutralizing antibodies capable of binding HPK specifically compete with a test compound for binding HPK. In this manner, the antibodies can be used to detect the presence of any peptide which shares one or more antigenic determinants with HPK. Diagnostic and Therapeutic Uses of the Polynucleotide Encoding HPK A polynucleotide designated herein as an HPK encoding sequence, or any part thereof, may be used for diagnostic and/or therapeutic purposes. For diagnostic purposes, the HPK encoding sequences of this invention may be used to detect and quantitate gene expression in biopsied tissues in which expression of HPK encoding sequences may be implicated. The diagnostic assay is useful to distinguish between absence, presence, and excess expression of HPK encoding sequences and to monitor regulation of HPK encoding sequences levels during therapeutic intervention. The association of HPK with disorders and disease conditions in specific tissues would greatly facilitate studies aimed at determining HPK function in these conditions and the development of therapeutic strategies to treat them. Included in the scope of the invention are oligonucleotide sequences, antisense RNA and DNA molecules, and PNAs. In another embodimdent of the subject invention hybridization or PCR probesare provided which are capable of detecting polynucleotide sequences, including genomic sequences. encoding HPK or closely related molecules. The specificity of the probe, whether it is made from a highly specific region, eg. 10 unique nucleotides in the 5' regulatory region, or a less specific region, eg. especially in the 3 " region, and the stringency of the hybridization or amplification (maximal, high, intermediate or low) will determine whether the probe identifies only naturally occurring HPK encoding sequences, alleles or related sequences. Probes may also be used for the detection of related sequences and should preferably contain at least 50% of the nucleotides from any of these HPK encoding sequences. The hybridization probes of the subject invention may be derived from the nucleotide sequences of SEQ ID NOs:2. 4.and 6 or from genomic sequences including promoter, enhancer elements and introns of the naturally occurring HPK encoding sequences. Hybridization probes may be labeled by a variety of reporter groups, including 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. Other means for producing specific hybridization probes for HPK encoding sequences DNAs include the cloning of nucleic acid sequences encoding HPK or HPK derivatives into vectors for the production of mRN A probes. Such vectors are known in the art and are commercially available and may be used to synthesize RNA probes in vitro by means of the addition of the appropriate RNA polymerase as T7 or SP6 RNA polymerase and the appropriate radioactively labeled nucleotides. Polynucleotide sequences encoding HPK may be used for the diagnosis of conditions or diseases with which the expression of HPK is associated. For example, polynucleotide sequences encoding HPK may be used in hybridization or PCR assays of fluids or tissues from biopsies to detect HPK encoding sequences expression. The form of such qualitative or quantitative methods may include southern or northern analysis, dot blot or other membrane-based technologies; PCR technologies; dip stick, pin. chip and ELISA technologies. All of these techniques are well known in the art and are the basis of many commercially available diagnostic kits. The HPK encoding nucleotide sequences disclosed herein provide the basis for assays that detect activation or induction of HPK encoding sequences associated with specific diseases. The HPK encoding nucleotide sequence may be labeled by methods known in the art and added to a fluid or tissue sample from a patient under conditions suitable for the formation of hybridization complexes. After an incubation period, the sample is washed with a compatible fluid which optionally contains a dye (or other label requiring a developer) if the nucleotide has been labeled with an enzyme. After the compatible fluid is rinsed off. the dye is quantitated and compared with a standard. If the amount of dye in the biopsied or extracted sample is significantly elevated over that of a comparable control sample, the nucleotide sequence has hybridized with nucleotide sequences in the sample, and the presence of elevated levels of HPK encoding nucleotide sequence in the sample indicates the presence of the associated disease. Such assays may also be used to evaluate the efficacy of a particular therapeutic treatment regime 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, a normal or standard profile for HPK encoding sequence expression must be established. This is accomplished by combining body fluids or cell extracts taken from normal subjects, cither animal or human, with an HPK encoding sequence, or a portion thereof, under conditions suitable for hybridization or amplification. Standard hybridization may be quantified by comparing the values obtained for normal subjects with a dilution series of an HPK encoding sequence run in the same experiment where a known amount of substantially purified HPK encoding sequence is used. Standard values obtained from normal samples may be compared with values obtained from samples from patients afflicted with HPK-associated diseases. Deviation between standard and subject values is used to establish the presence of disease. Once disease is established, a therapeutic agent is administered and a treatment profile is generated. Such assays may be repeated on a regular basis to evaluate whether the values in the profile progress toward or return to the normal or standard pattern. Successive treatment profiles may be used to show the efficacy of treatment over a period of several days or several months. PCR. may be used to provide additional uses for oligonucleotides based upon the HPK sequence. Such oligomers are generally chemically synthesized, but they may be generated enzymatically or produced from a recombinant source. Oligomers generally comprise two nucleotide sequences, one with sense orientation (5'->3') and one 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. Additionally, methods which may be used to quantitate the expression of a particular molecule include radiolabeling or biotinylating nucleotides, coamplification of a control nucleic acid, and standard curves onto which the experimental results are interpolated (Melby PC et al (1993) J Immunol Methods 159:235-44: Duplaa C et al (1993) Anal Biochem 229-36). 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. A definitive diagnosis of this type may allow health professionals to begin aggressive treatment and prevent further degeneration of the condition. Similarly, further assays can be used to monitor the progress of a patient during treatment. Furthermore, the nucleotide sequences disclosed herein may be used in molecular biology techniques that have not yet been developed, provided the new techniques rely on properties of nucleotide sequences that are currently known such as the triplet genetic code, specific base pair interactions, and the like. For therapeutic purposes, an antisense molecule of an HPK encoding sequence may provide a basis for treatment where down-regulation of the gene and consequent inhibition of its activity is desirable. Alternatively, sequences encoding HPK may provide the basis for gene therapy in conditions where it may be desirable to increase expression of HPK and hence increase its activity. Expression vectors derived from retroviruses. 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 recombinant vectors which will express antisense HPK. See, for example, the techniques described in Sambrook et al (supra) and Ausubel et al (supra). The polynucleotides comprising full length cDNA sequences encoding HPK and/or its regulatory elements may be used in research as an investigative tool in sense or antisense regulation of gene function (Youssoufian H and HF Lodish 1993 Mol Cell Biol 13:98-104; Eguchi et al (1991 ) Annu Rev Biochem 60:631-652). Such technology is now well known in the art, and sense or antisense oligomers, or larger fragments, can be designed from various locations along the coding or control regions. Genes encoding HPK can be turned off by transfecting a cell or tissue with expression vectors which express high levels of a desired HPK encoding sequence fragment. Such constructs can flood cells with untranslatable sense or antisense sequences. Even in the absence of integration into the DNA, such vectors may continue to transcribe RNA molecules until all copies are disabled by endogenous nucleases. Transient expression may last for a month or more with a non-replicating vector and even longer if appropriate replication elements are part of the vector system (Mettler I. personal communication). As mentioned above, modifications of gene expression can be obtained by designing antisense molecules, DNA. RNA or PNA. to the control regions of HPK encoding sequences, ie. the promoters, enhancers, and introns. Oligonucleotides derived from the transcription initiation site, eg, between -10 and +10 regions of the leader sequence, are preferred. The antisense molecules may also be designed to block translation of mRNA by preventing the transcript from binding to ribosomes. Similarly, inhibition can be achieved using "triple helix" base-pairing methodology. Triple helix pairing compromises the ability of the double helix to open sufficiently for the binding of polymerases. transcription factors, or regulatory molecules. Recent therapeutic advances using triplex DNA were reviewed by Gee JE et al (In: Huber BE and BI Can * ( 1994) Molecular and immunologic Approaches. Futura Publishing Co. Mt Kisco NY). Ribozymes are enzymatic RNA molecules capable of catalyzing the specific cleavage of RNA. The mechanism of ribozyme action involves sequence-specific hybridization of the ribozyme molecule to complementary target RNA, followed by endonucleolytic cleavage. Another embodiment involves engineering hammerhead motif ribozyme molecules that can specifically and efficiently catalyze endonucleolytic cleavage of HPK encoding sequences. Specific ribozyme cleavage sites within any potential RNA target are initially identified by scanning the target molecule for ribozyme cleavage sites which include the following sequences. GUA, GUU and GUC. Once identified, short RNA sequences of between 15 and 20 ribonucleotides corresponding to the region of the 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 hybridization with complementary oligonucleotides using ribonuclease protection assays. Antisense molecules and ribozymes of the invention may be prepared by any method known in the art for the synthesis of RNA 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 HPK. Such DNA sequences may be incorporated into a wide variety of vectors with suitable RNA polymerase promoters such as T7 or SP6. Alternatively, antisense cDNA constructs that synthesize antisense 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 of the molecule or the use of phosphorothioate or 2' O-methyl rather than phosphodiestera.se linkages within the backbone of the 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. Methods for introducing vectors into cells or tissues include those methods discussed infra and which are equally suitable for in vivo, in vitro and ex vivo therapy. 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 and by liposome are quite well known in the art. Furthermore, the nucleotide sequences for HPK encoding sequences disclosed herein may be used in molecular biology techniques that have not yet been developed, provided the new techniques rely on properties of nucleotide sequences that are currently known, including but not limited to such properties as the triplet genetic code and specific base pair interactions. Detection and Mapping of Related Polynucleotide Sequences The nucleic acid sequence for HPK can also be used to generate hybridization probes for mapping the naturally occurring genomic sequence. The sequence may be mapped to a particular chromosome or to a specific region of the chromosome using well known techniques. These include in situ hybridization to chromosomal spreads, flow-sorted chromosomal preparations, or artificial chromosome constructions such as veast artificial chromosomes, bacterial artificial chromosomes, bacterial PI constructions or single chromosome cDNA libraries as reviewed in Price CM (1993; Blood Rev 7:127-34) and Trask BJ (1991 ; Trends Genet 7:149-54). The technique of fluorescent in sjtu hybridization of chromosome spreads has been described, among other places, in Verma et al ( 1988) Human Chromosomes: A Manual of Basic Techniques. Pergamon Press, New York NY. Fluorescent in situ hybridization of chromosomal preparations and other physical chromosome mapping techniques may be correlated with additional genetic map data. Examples of genetic map data can be found in the 1994 Genome Issue of Science (265: 198 If). Correlation between the location of an HPK encoding sequence 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 of the 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. For example, a sequence tagged site based map of the human genome was recently published by the Whitehead-MIT Center for Genomic Research (Hudson TJ et al (1995) Science 270: 1945- 1954). Often the placement of a gene on the chromosome of another mammalian species such as mouse (Whitehead Institute/MIT Center for Genome Research. Genetic Map of the Mouse. Database Release 10, April 28, 1995) 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 a disease or syndrome, such as ataxia telangiectasia (AT), has been crudely localized by genetic linkage to a particular genomic region, for example, AT to 1 l q22-23 (Gatti 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 of the subject invention may also be used to detect differences in the chromosomal location due to translocation. inversion, etc. among normal, carrier or affected individuals Pharmaceutical Compositions The present invention relates to pharmaceutical compositions which may comprise nucleotides. proteins, antibodies, agonists, antagonists, or inhibitors, 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. Any of these molecules can be administered to a patient alone, or in combination with other agents, drugs or hormones, in pharmaceutical compositions where it is mixed with excipient(s) or pharmaceutically acceptable carriers. In one embodiment of the present invention, the pharmaceutically acceptable carrier is pharmaceutically inert. Administration of Pharmaceutical Compositions Pharmaceutical compositions may be administerred to any subject in need of treatment including, but not limited to, humans and domestic animals. Administration of pharmaceutical compositions is accomplished orally or parenterally. Methods of parenteral delivery include topical, intra-arterial (directly to the tumor), intramuscular, subcutaneous, intramedullary, intrathecal. intraventricular. intravenous, intraperitoneal. or intranasal administration. 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: and 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 are provided 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, ie, 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 paraffin, or liquid polyethylene glycol with or without stabilizers. Pharmaceutical formulations for parenteral administration include aqueous solutions of active compounds. For injection, the pharmaceutical compositions of the invention 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 of the 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 trigiycerides. or liposomes. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the 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. Manufacture and Storage The pharmaceutical compositions of the present invention may be manufactured in a manner that known in the art, eg, 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 that are the corresponding free base forms. In other cases, the preferred preparation may be a lyophilized powder in lmM-50 mM histidine. 0.1%-2% sucrose, 2%-7% mannitol at a pH range of 4.5 to 5.5 that is combined with buffer prior to use. After pharmaceutical compositions comprising a compound of the invention formulated in a acceptable carrier have been prepared, they can be placed in an appropriate container and labeled for treatment of an indicated condition. For administration of HPK, such labeling would include amount, frequency and method of administration. Therapeutically Effective Dose Pharmaceutical compositions suitable for use in the present 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, eg. of neoplastic cells, or in animal models, usually mice, rabbits, dogs, or pigs. The animal model is also used to achieve a desirable 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 protein or its antibodies. antagonists, or inhibitors which ameliorate the symptoms or condition. Therapeutic efficacy and toxicity of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, eg, ED50 (the dose therapeutically effective in 50% of the population) and LD50 (the dose lethal to 50% of the 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 of such compounds lies 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 of the patient, and the route of administration. The exact dosage is chosen by the individual physician in view of the patient to be treated. Dosage and administration are adjusted to provide sufficient levels of the active moiety or to maintain the desired effect. Additional factors which may be taken into account include the severity of the disease state, eg. tumor size and location: age. weight and gender of the patient: diet, time and frequency of administration, drug combination(s), reaction sensitivities, and tolerance/response to therapy. Long acting pharmaceutical compositions might be administered every 3 to 4 days, every week, or once every two weeks depending on half-life and clearance rate of the 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 generally available in the scientific literature. 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. It is contemplated, for example, that molecules or compounds that modulate HPK activity, such as antibodies of HPK. or an HPK derivative can be delivered in a suitable formulation as a therapeutic agent. Similarly, administration of agonists should also improve the activity or lifespan of this protein and lessen the onset and progression of senescence. The examples below are provided to illustrate the subject invention and are not included for the purpose of limiting the invention. INDUSTRIAL APPLICABILITY I HPK-1 HIPONOTO1 cDNA Library Construction The hippocampus used for this library was obtained from the Keystone Skin Bank, International Institute for the Advancement of Medicine (Exton, PA). Hippocampus tissue from 72 year old Caucasian female (RF94-09083) was flash frozen, ground in a mortar and pestle.and lyzed immediately in buffer containing guanidinium isothiocyanate. Lysis was followed by several phenol chloroform extractions and ethanol precipitation. Poly A+ RNA was isolated using biotinylated oligo d(T) primer and streptavidin coupled to paramagnetic particles (Promega Corp. Madison WI) and sent to Stratagene. Stratagene prepared the cDNA library using oligo d(T) priming. Synthetic adapter oligonucleotides were ligated onto the cDNA molecules enabling them to be inserted into the Uni-ZAP™ vector system (Stratagene). The quality of the cDNA library was screened using DNA probes, and then the pBluescript phagemid (Stratagene) was excised. Subsequently, the custom-constructed library phage particles were infected into E. coli host strain XL1 Blue (Stratagene). Alternative unidirectional vectors might include, but are not limited to. pcDNAI (Invitrogen) and pSHlox-1 (Novagen). The phagemid forms of individual cDNA clones were obtained by the in vivo excision process, in which the host bacterial strain was co-infected with both the library phage and an fl helper phage. Polypeptides or enzymes derived from both the library-containing phage and the helper phage nicked the DNA. initiated new DNA synthesis from defined sequences on the target DNA, and created a smaller, single stranded circular phagemid DNA molecule that included all DNA sequences of the pBluescript phagemid and the cDNA insert. The phagemid DNA was released from the cells and purified, and used to reinfect fresh host cells (SOLR, Stratagene) where double-stranded phagemid DNA was produced. Because the phagemid carries the gene for b-lactamase. the newly transformed bacteria were selected on medium containing ampicillin. Phagemid DNA was purified using the QIAWELL-8 Plasmid Purification System from the QIAGEN DNA Purification System (QIAGEN IncChatsworth.CA). The DNA was eluted from the purification resin and prepared for DNA sequencing and other analytical manipulations. II HPK-2 TMLR30T01 cDNA Library Construction The normal peripheral blood T-lymphocytes used for this library were obtained from two 24 year old. Caucasian males. This library represents a mixture of allogeneically stimulated human T cell populations obtained from Ficoll/Hypaque purified buffy coats. The cells from the two different donors (not typed for HLA alleles) were incubated at a density of 1 x 106/ml, cultured for 96 hours in DME containing 10% human serum, washed in PBS, scraped and lyzed immediately in buffer containing guanidinium isothiocyanate. The lysate was extracted twice with a mixture of phenol and chloroform, pH 8.0 and centrifuged over a CsCl cushion using an Beckman SW28 rotor in a L8-70M Ultracentrifuge (Beckman Instruments). The RNA was precipitated using 0.3 M sodium acetate and 2.5 volumes of ethanol. resuspended in water and DNase treated for 15 min at 37C. The total RNA was isolated using the Qiagen Oligotex kit (QIAGEN Inc. Chatsworth CA). It must be noted that B lymphocytes were not removed, and some contaminating macrophages may also have been present. Stratagene (La Jolla CA) used the total RNA to construct a custom cDNA library essentially as descibed above. The cDNAs were inserted into the LambdaZap™ vector system (Stratagene); and the vector was transformed into cells of E. coli, strain XLl-BlueMRF (Stratagene). The phagemid forms of individual cDNA clones were obtained by the in vivo excision process previously described. Plasmid DNA was released from the cells and purified using the Miniprep Kit (Catalogue # 77468; Advanced Genetic Technologies Corporation, Gaithersburg MD), as previously described (Section V). Alternative methods of purifying plasmid DNA include the use of MAGIC MINIPREPS- DNA Purification System (Catalogue #A7100, Promega, Madison WI)or QIAwell--8 Plasmid. QIAwell PLUS DNA and QIAwell ULTRA DNA Purification Systems (QIAGEN Chatsworth CA). ->- HI HPK-3 MPHGNOTO3 cDNA Library Construction Peripheral blood was obtained from a 24 year old, Caucasian male. Mononuclear cells were separated from heparinized venous blood after centrifugation through Ficoll/Hypaque using HIST0PAQUE®-1 1 19 and HISTOPAQUE®-1077. available from Sigma Diagnostics (St Louis MO). The Ficoll/Hypaque buffy coat which contains peripheral blood mononuclear cells was put into sterile Petri dishes and cultured for between 3 to 5 days in Dulbecco " s minimum essential medium (DME) supplemented with 10% human serum. After incubation, macrophages mostly adhered to the plastic surface, whereas most other cell types, B and T lymphocytes, remained in solution. The DME was decanted from the wells and washed with phosphate buffered saline (PBS). Macrophages were released from the plastic surface by gently scraping the Petri dishes in PBS/1 mM EDTA. Macrophages were lysed immediately in buffer containing guanidinium isothiocyanate. The lysate was extracted twice with a mixture of phenol and chloroform, pH 8.0 and centrifuged over a CsCl cushion using an Beckman SW28 rotor in a L8-70M Ultracentrifuge (Beckman Instruments). The RNA was precipitated using 0.3 M sodium acetate and 2.5 volumes of ethanol. resuspended in water and DNase treated for 15 min at 37%C. The total RNA was isolated using the Qiagen Oligotex kit (QIAGEN Inc. Chatsworth CA). It must be noted that some contaminating T and B lymphocytes may also have been present. The poly A+ RNA was used to construct the MPHGNOT03 cDNA library, phagemid forms of individual cDNA clones were obtained by the in vivo excision process, and plasmid DNA was released and recovered from the cells using the Miniprep Kit (Catalogue # 77468. Advanced Genetic Technologies Corporation. Gaithersburg MD). as described above. IV Sequencing of cDNA Clones The cDNAs were sequenced by the method of Sanger F and AR Coulson (1975; J Mol Biol 94:44 If), using a Catalyst 800 Hamilton Micro Lab 2200 (Hamilton. Reno NV) in combination with four Peltier Thermal Cyclers (PTC200 from MJ Research, Watertown MA) and Applied Biosystems 377 or 373 DNA Sequencing Systems (Perkin Elmer) and the reading frame was determined. V Homology Searching of cDNA Clones and Their Deduced Proteins Each cDNA was compared to sequences in GenBank using a search algorithm developed by Applied Biosystems and incorporated into the INHERIT'" 670 Sequence Analysis System. In this algorithm. Pattern Specification Language (TRW Inc. Los Angeles CA) was used to determine regions of homology. The three parameters that determine how the sequence comparisons run were window size, window offset, and error tolerance. Using a combination of these three parameters, the DNA database was searched for sequences containing regions of homology to the query sequence, and the appropriate sequences were scored with an initial value. Subsequently, these homologous regions were examined using dot matrix homology plots to distinguish regions of homology from chance matches. Smith- Waterman alignments were used to display the results of the homology search. Peptide and protein sequence homologies were ascertained using the INHERIT ™ 670 Sequence Analysis System in a way similar to that used in DNA sequence homologies. Pattern Specification Language and parameter windows were used to search protein databases for sequences containing regions of homology which were scored with an initial value. Dot-matrix homology plots were examined to distinguish regions of significant homology from chance matches. 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). was used to search for local sequence alignments. BLAST produces alignments of both nucleotide and amino acid sequences to determine sequence similarity. Because of the local nature of the alignments, BLAST is especially useful in determining exact matches or in identifying homologs. BLAST is useful for matches which do not contain gaps. The fundamental unit of BLAST algorithm output is the High-scoring Segment Pair (HSP). An HSP consists of two sequence fragments of arbitrary but equal lengths whose alignment is locally maximal and for which the alignment score meets or exceeds a threshold or cutoff score set by the user. The BLAST approach is to look for HSPs 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. The parameter E establishes the statistically significant threshold for reporting database sequence matches. E is interpreted as the upper bound of the expected frequency of chance occurrence of an HSP (or set of HSPs) within the context of the entire database search. Any database sequence whose match satisfies E is reported in the program output. VI 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 labelled 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 SF 1993 and 1990, supra) are used to search for identical or related molecules in nucleotide databases such as GenBank or the LIFESEQ™ database (Incyte. Palo Alto CA). This analysis is much faster than multiple. membrane-based hybridizations. In addition, the sensitivity of the computer search can be modified to determine whether any particular match is categorized as exact or homologous. The basis of the search is the product score which is defined as: % sequence identity x % maximum BLAST score 100 and it takes into acccount both the degree of similarity between two sequences and the length of the 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. VII Extension of HPK to Full Length or to Recover Regulatory Elements The nucleic acid sequence of full length HPK encoding sequences (SEQ ID Nos:2, 4, or 6) is used to design oligonucleotide primers for extending a partial nucleotide sequence to full length or for obtaining 5' sequences from genomic libraries. One primer is synthesized to initiate extension in the antisense direction (XLR) and the other is synthesized to extend sequence in the sense direction (XLF). Primers allow the extension of the known HPK encoding sequences "outward " generating amplicons containing new. unknown nucleotide sequences for the region of interest (US Patent Application 08/487.1 12). The initial primers are designed from the cDNA using OLIGO* 4.06 Primer Analysis Software (National Biosciences). 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. Any stretch of nucleotides which would result in hairpin structures and primer-primer dimerizations is avoided. The original, selected cDNA libraries, or a human genomic library are used to extend the sequence; the latter is most useful to obtain 5' upstream regions. If more extension is necessary or desired, additional sets of primers are designed to further extend the known region. By following the instructions for the XL-PCR kit (Perkin Elmer) and thoroughly mixing the enzyme and reaction mix. high fidelity amplification is obtained. Beginning with 40 pmol of each primer and the recommended concentrations of all other components of the kit, PCR is performed using the Peltier Thermal Cycler (PTC200; MJ 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 1 1 Repeat step 8-10 for 12 cycles Step 12 72% C for 8 min Step 13 4% C (and holding) A 5-10 microliteri aliquot of the reaction mixture is 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 selected and cut out of the gel. Further purification involves using a commercial gel extraction method such as QIAQuick™ (QIAGEN Inc). After recovery of the DNA. Klenow enzyme was used to trim single-stranded, nucleotide overhangs creating blunt ends which facilitate religation and cloning. After ethanol precipitation, the products are redissolved in 13 microliter of ligation buffer. 1 microliter T4-DNA ligase ( 15 units) and 1 microliter T4 polynucleotide kinase are added, and the mixture is incubated at room temperature for 2-3 hours or overnight at 16% C. Competent E, coli cells (in 40 &1 of appropriate media) are transformed with 3 microliter of ligation mixture and cultured in 80 &l of SOC medium (Sambrook J et al, supra). After incubation for one hour at 37% C, the whole transformation mixture is plated on Luria Bertani (LB)-agar (Sambrook J et al, supra) containing 2xCarb. The following day, several colonies are randomly picked from each plate and cultured in 150 microliter of liquid LB/2xCarb medium placed in an individual well of an appropriate, commercially-available, sterile 96-well microtiter plate. The following day, 5 microliter of each overnight culture is transferred into a non- sterile 96-well plate and after dilution 1:10 with water. 5 microliter of each sample is transferred into a PCR array. For PCR amplification. 18 microliter of concentrated PCR reaction mix (3.3x) containing 4 units of rTth DNA polymerase, a vector primer and one or both of the gene specific primers used for the extension reaction are added to each well. Amplification is 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 of the PCR reactions are run on agarose gels together with molecular weight markers. The sizes of the PCR products are compared to the original partial cDNAs, and appropriate clones are selected, ligated into plasmid and sequenced. VIII Labeling and Use of 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 cDNA 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 mCi of [- 32 P] adenosine triphosphate (Amersham, Chicago IL) and T4 polynucleotide kinase (DuPont NEN*-. Boston MA). The labeled oligonucleotides are substantially purified with Sephadex G-25 super fine resin column (Pharmacia). A portion containing 10 7 counts per minute of each of the sense and antisense oligonucleotides is used in a typical membrane based hybridization analysis of human genomic DNA digested with one of the 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 (Nvtran 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. IX Antisense Molecules The HPK encoding sequence, or any part thereof, is used to inhibit in vivo or in vitro expression of naturally occurring HPK encoding sequences. Although use of antisense oligonucleotides. comprising about 20 base-pairs, is specifically described, essentially the same procedure is used with larger cDNA fragments. For example, an oligonucleotide based on the coding sequence of HPK-1 as shown in Figures 1 A. IB. 1C and ID is used to inhibit expression of naturally occurring HPK. The complementary oligonucleotide is designed from the most unique 5' sequence as shown in Figures 1 A. IB, 1C and ID and used to inhibit translation of an HPK encoding sequences transcript by preventing the ribosome from binding. Using an appropriate portion of the leader and 5 " sequence of SEQ ID NO:2, an effective antisense oligonucleotide includes any 15-20 nucleotides spanning the region which translates into the signal or early coding sequence of the polypeptide as shown in Figures 1A, I B. 1 C and ID. X Expression of HPK Expression of the HPK is accomplished by subcloning the cDNAs into appropriate vectors and transfecting the vectors into host cells. In this case, the cloning vector, pSport. previously used for the generation of the cDNA library is used to express HPK in £. coli. Upstream of the cloning site, this vector contains a promoter for β-galactosidase. followed by sequence containing the amino-terminal Met and the subsequent 7 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, transfected bacterial strain with IPTG using standard methods produces a fusion protein which consists of the first seven residues of β-galactosidase. about 5 to 15 residues of linker, and the full length HPK. The signal sequence directs the secretion of HPK into the bacterial growth media which can be used directly in the following assay for activity. XI HPK Activity HPK activity may be measured by phosphorylation of a protein substrate using gamma-labeled P-ATP and quantitation of the incorporated radioactivity using a gamma radioisotope counter. HPK is incubated with the protein substrate, 3: P-ATP, and a kinase buffer. The 32 P incorporated into the substrate is then separated from free 3: P-ATP by electrophoresis and the incorporated 32 P is counted. A determination of the specific amino acid residues phosphorylated is made by phosphoamino acid analysis of the hydrolyzed protein as described by Boyle WJ et al (1991) Methods in Enzymol 201 : 1 10-148. XII Production of HPK Specific Antibodies HPK substantially purified using PAGE electrophoresis (Sambrook, supra) is used to immunize rabbits and to produce antibodies using standard protocols. The amino acid sequence translated from HPK is analyzed using DNAStar software (DNAStar Inc) to determine regions of high immunogenicity and a corresponding oligopolypeptide is synthesized and used to raise antibodies by means known to those of skill in the art. Analysis to select appropriate epitopes, such as those near the C-terminus or in hydrophilic regions (shown in Figures 4A, 4B. 4C and 4D) is described by Ausubel FM et al (supra). 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) by reaction with M-maleimidobenzoyl-N-hydroxysuccinimide ester (MBS; Ausubel FM 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 radioiodinated, goat anti-rabbit IgG. XIII Purification of Naturally Occurring HPK Using Specific Antibodies Naturally occurring or recombinant HPK is substantially purified by immunoaffinity chromatography using antibodies specific for HPK. An immunoaffinity column is constructed by covalently coupling HPK antibody to an activated chromatographic resin such as CnBr-activated Sepharose (Pharmacia Biotech). After the coupling, the resin is blocked and washed according to the manufacturer's instructions. Media containing HPK is passed over the immunoaffinity column, and the column is washed under conditions that allow the preferential absorbance of HPK (eg, high ionic strength buffers in the presence of detergent). The column is eluted under conditions that disrupt antibody/HPK binding (eg. a buffer of pH 2-3 or a high concentration of a chaotrope such as urea or thiocyanate ion), and HPK is collected. XIV Identification of Molecules Which Interact with HPK HPK, or biologically active fragments thereof, are labelled with l 5 I Bolton-Hunter reagent (Bolton AE and Hunter WM (1973) Biochem J 133:529). Candidate molecules previously arrayed in the wells of a 96 well plate are incubated with the labelled HPK, washed and any wells with labelled HPK complex are assayed. Data obtained using different concentrations of HPK are used to calculate values for the number, affinity, and association of HPK with the candidate molecules. All publications and patents mentioned in the above specification are herein incorporated by reference.
