NUCLEAR HORMONE RECEPTOR-INTERACTING POLYPEPTIDES AND RELATED MOLECULES AND METHODS

Abstract: Disclosed is a method for determining whether a test protein is capable of interacting with a nuclear hormone receptor protein. The method involves: (a) providing a host cell which contains (i) a reporter gene operably linked to a protein binding site; (ii) a first fusion gene which expresses a first fusion protein, the first fusion protein including a nuclear hormone receptor protein covalently bonded to a binding moiety which is capable of specifically binding to the protein binding site; and (iii) a second fusion gene which expresses a second fusion protein, the second fusion protein including the test protein covalently bonded to a weak gene activating moiety; and (b) determining whether the test protein increases expression of the reporter gene as an indication of its ability to interact with the nuclear hormone receptor protein. Such an interaction may be hormone dependent, hormone independent, or hormone sensitive.

Description: NUCLEAR HORMONE RECEPTOR-INTERACTING POLYPEPTIDES AND RELATED MOLECULES AND METHODS Background of the Invention This invention relates to receptor proteins. The diverse physiological and developmental effects of thyroid hormone receptor (for example, T3) are mediated by the three hormone-binding isoforms of the T3 receptor: TRαl, TR/31, and TR/32. The effects of the hormone are the consequences of changes in expression of a wide range of target genes that result from T3 binding to these receptors. While it is unknown how binding of the ligand to the receptor actually causes such changes in gene expression, the basic effects on the rate of transcription are believed to be a consequence of direct or indirect protein-protein contacts between the TRs and components of basic transcriptional apparatus, such as RNA polymerase or associated proteins. In addition, interactions of TRs with other transcription factors are thought to result in a variety of complex combinatorial regulatory effects. In recent years there has been very rapid progress in unravelling the most basic aspects of the mechanism of T3 action in the control of gene expression (see Brent et al., Ann. Rev. Physiol. 53:17-35, 1991 for recent review) . It is now clear that the T3 receptors are transcription factors that belong to a related superfamily of nuclear hormone receptors. This family of proteins interacts not only with diverse ligands but also with a complex array of similar DNA binding sites. Like other DNA binding transcription factors, the TRs function by increasing (or, in some cases, decreasing) the rate of transcription initiation from a linked promoter. The details of the mechanisms that cause such alterations remain unclear and are the focus of intense study in a number of systems (see Lewin, Cell 61:1161- 1164, 1990; Ptashne, Sci. Am. 260:40-47, 1989; Ptashne, and Gann, Nature 346:329-331, 1990, for reviews). However, two broad themes are evident. The first is that transcription factors in general are frequently modular, composed of distinct domains with separate DNA binding and transcriptional regulatory functions. With TRs, for example, it is apparent that the DNA binding and ligand binding domains are quite separate, and experiments with chimeric receptors make it clear that the T3 dependent activation of gene expression can be transferred to heterologous DNA binding domains (see, e.g., Holloway, Proc. Natl. Acad. Sci. USA 87:8160-8164, 1990; Thompson and Evans, Proc. Natl. Acad. Sci. USA 86:3494-3498, 1989). A second theme is that the functions of transcription factors are believed to be a consequence of protein-protein interactions with the basic transcriptional apparatus. It is thought that these interactions are mediated by proteins called coactivators or adaptors (see Ptashne and Gann, Nature 346:329-331, 1990) . These poorly characterized proteins act as bridges between the transcriptional activation domain that is tethered to the DNA by the transcription factor and the RNA polymerase complex bound at the initiation site. Via unknown mechanisms, this interaction leads to an increase in promoter activity. Protein-protein contacts are also essential for a surprisingly diverse array of positive and negative interactions between transcription factors. Recent results in several systems indicate that this mechanism leads to complex regulatory networks that allow cross talk between various signalling pathways. In the case of TRs, three such interactions have been described to date. The first is the heterodimeric interaction of TRs with the related RXRs (Bugge et al., EMBO J 11:1409-1418, 1992; Kliewer et al., Nature 355:446-449, 1992; Lied et al., Cell 68:377-395, 1992; Marks et al., EMBO J 11:1419- 1435, 1992; Yu et al. , Cell 67:1251-1266, 1991; Zhang et al.. Nature 355:441-446, 1992). TR/RXR heterodimers show higher DNA binding affinity to thyroid hormone response elements (i.e., T3RE sites) initially characterized as binding TR homodimers (see, e.g., Williams et al. , J. Biol. Chem. 266:19636-19644, 1991), but heterodimerization does not appear to alter site specificity. A second, less direct interaction is reflected in the mutually antagonistic effects of the TRs and the c- jun and c-fos protooncogenes (Desbois et al., Cell 67:731-740, 1991; Zhang et al. , Mol. Cell. Biol. 11:6016- 6025, 1991) . The heterodimeric complex of these two leucine zipper transcription factors is frequently referred to as AP-1, although the jun-jun homodimers and other complexes containing related but less well characterized proteins can also bind the consensus AP-1 site. Such sites are also referred to as TPA response elements (i.e., TREs) (here distinguished from T3REs) because the induction of protein kinase C activity by TPA or other phorbol esters results in a very rapid induction of AP-1 activity (reviewed in (Curran and Franza, Cell 55:395-397, 1988). The activity of the TRs is antagonized by coexpression of active jun or fos, and the TRs exert a complimentary inhibition of jun and fos activity. Although the mechanism of this interaction is unknown, it does not require the presence of overlapping DNA binding sites. Thus, TRs can antagonize TPA response on a promoter that does not contain a T3RE, and jun and fos can antagonize T3 response on a promoter that does not include a TRE. Interestingly, although TRs are always nuclear and are able to bind T3REs whether or not hormone is present, the antagonistic function is only observed when T3 is present. The antagonistic interaction with jun and fos is also observed with other members of the superfamily, including RARs (Desbois et al.. Cell 67:731-740, 1991; Schule et al., Proc. Natl. Acad. Sci. USA 88:6092-6096, 1991) and GRs (Jonat et al., Cell 62:1189-1204; Schule et al., Cell 62:1217-1226, 1990; Yang-Yen et al., Cell 62:1205-1215, 1990). The GR interaction was the first described and has been the best characterized, but the biochemical basis for the effect remains uncertain (see Ponta et al., Acta 1129:255-261, 1992 for a review). Despite the potential importance of this apparent cross¬ talk between nuclear hormone receptors and the protein kinase C signalling pathway, its physiologic impact also remains unclear. Finally, TRs have also been reported to interact both functionally and biochemically with the cell-type specific transcriptional activator Pit-1 (Schaufele et al., Mol. Endocrinol. 6:656-665, 1992). In contrast to the antagonistic effects of TRs and AP-1, this interaction apparently leads to synergistic activation. These distinct mechanisms for the modulation of transcriptional activation remain quite unclear. It is apparent that the identification and characterization of proteins capable of interacting specifically with the TRs could provide important clues to these processes and other potential functions of the receptors, such as regulation of cell proliferation (Halperin et al., Endocrinology 126:2321-2326, 1990). In addition, interacting proteins provide a means of controlling and modulating thyroid hormone receptor function. Summary of the Invention In a first aspect, the invention generally features a method for determining whether a test protein is capable of interacting with a nuclear hormone receptor protein. The method involves: (a) providing a host cell which contains (i) a reporter gene operably linked to a protein binding site; (ii) a first fusion gene which expresses a first fusion protein, the first fusion protein including a nuclear hormone receptor protein covalently bonded to a binding moiety which is capable of specifically binding to the protein binding site; and (iii) a second fusion gene which expresses a second fusion protein, the second fusion protein including the test protein covalently bonded to a weak gene activating moiety; and (b) determining whether the test protein increases expression of the reporter gene as an indication of its ability to interact with the nuclear hormone receptor protein. In a preferred embodiment, the method further involves treating the host cell with a ligand which binds the nuclear hormone receptor and identifying a hormone- dependent interacting protein by its ability to increase expression of the reporter gene only upon treatment of the cell by the ligand. In another preferred embodiment, the method further involves treating the host cell with a ligand which binds the nuclear hormone receptor and identifying a hormone-independent interacting protein by its ability to increase expression of the reporter gene both in the presence and in the absence of ligand treatment. In yet another preferred embodiment, the method further involves treating the host cell with a ligand which binds the nuclear hormone receptor and identifying a ligand-sensitive interacting protein by its ability to increase expression of the reporter gene in the absence but not in the presence of the ligand treatment. Preferably, the ligand is a thyroid hormone. In other preferred embodiments, the weak gene activating moiety is the gene activating moiety of B42 or a gene activating moiety of lesser activation potential; and the nuclear hormone receptor is a thyroid hormone receptor. In a second aspect, the invention features a substantially pure preparation of a thyroid hormone receptor (TR)-interacting protein. Preferably, the TR- interacting protein is JL-1 or JL-2; includes an amino acid sequence substantially identical to an amino acid sequence shown in any of Figs. 2-28 (SEQ ID NOS: 1, 3, 6- 30) ; and is derived from a mammal, for example, a human. In a related aspect, the invention features purified DNA (for example, cDNA) which includes a sequence encoding a TR-interacting protein, preferably encoding a human TR-interacting protein, for example, the TR-interacting proteins JL-1 or JL-2. In other related aspects, the invention features a vector and a cell which includes a purified DNA of the invention; a purified antibody which specifically binds a TR-interacting protein of the invention; and a method of producing a recombinant TR-interacting protein involving providing a cell transformed with DNA encoding a TR- interacting protein positioned for expression in the cell; culturing the transformed cell under conditions for expressing the DNA; and isolating the recombinant TR- interacting protein. The invention further features recombinant TR-interacting protein produced by such expression of a purified DNA of the invention. In yet another aspect, the invention features a therapeutic composition which includes as an active ingredient a TR-interacting protein of the invention, the active ingredient being formulated in a physiologically- acceptable carrier. Such therapeutic compositions are useful in a method of treating thyroid disorders in a mammal, involving administering the therapeutic composition to the mammal in a dosage effective to increase thyroid function (in the case of hypothyroidism) or decrease thyroid function (in the case of hyperthyroidism) . As used herein, "reporter gene" is meant a gene whose expression may be assayed; such genes include, without limitation, la.cZ, amino acid biosynthetic genes, e.g. the yeast LEU2 gene, or the mammalian chloramphenicol transacetylase (CAT) gene. Reporter genes may be integrated into the chromosome or may be carried on autonomously replicating plasmids (e.g., yeast 2μ plasmids) . By "operably linked" is meant that a gene and a regulatory sequence(s) are connected in such a way as to permit gene expression when the appropriate molecules (e.g., transcriptional activator proteins or proteins which include transcriptional activation domains) are bound to the regulatory sequence(s) . By a "binding moiety" is meant a stretch of amino acids which is capable of directing specific polypeptide binding to a particular DNA sequence (i.e., a "protein binding site") . LexA represents a preferred DNA binding moiety in the invention. However, any other transcriptionally-inert or essentially transcriptionally- inert DNA binding domain may be substituted. The GAL4 DNA binding domain represents a somewhat less preferred DNA binding moiety for the system described herein. By "weak gene activating moiety" is meant a stretch of amino acids which is capable of weakly inducing the expression of a gene to whose control region it is bound. As used herein, "weakly" is meant below the level of activarion effected by GAL4 activation region II (Ma and Ptashne, Cell 48:847, 1987) and is preferably at or below the level of activation effected by the B42 activation domain of Ma and Ptashne (Cell 51:113, 1987). Levels of activation may be measured using any downstream reporter gene system and comparing, in parallel assays, the level of expression stimulated by the GAL4- or B42- polypeptide with the level of expression stimulated by the polypeptide to be tested. By "TR-interacting protein" is meant a polypeptide which directly or indirectly physically interacts with a thyroid hormone receptor in the in vivo protein interaction assay described herein. Such an interaction may be thyroid hormone dependent or independent or may be thyroid hormone sensitive; it may also be transient in nature. Preferably, such a polypeptide has an amino acid sequence which is at least 80%, preferably 90%, and most preferably 95% or even 99% homologous to the amino acid sequence of an interacting protein described herein (e.g., JL-1 or JL-2) at the point of interaction with the thyroid hormone receptor, or at least 80% and preferably 90% homologous overall. A "TR-interacting protein", as used herein, does not include any of the RXR proteins or Pit-i. By "thyroid hormone" is meant T3, triac, or T4, and less preferably reverse T3. By "substantially pure" is meant a preparation which is at least 60% by weight (dry weight) the compound of interest, i.e., a TR-interacting protein. Preferably the preparation is at least 75%, more preferably at least 90%, and most preferably at least 99%, by weight the compound of interest. Purity can be measured by any appropriate method, e.g., column chromatography, polyacrylamide gel electrophoresis, or HPLC analysis. By "purified DNA" is meant DNA that is not immediately contiguous with both of the coding sequences with which it is immediately contiguous (one on the 5' end and one on the 3' end) in the naturally occurring genome of the organism from which it is derived. The term therefore includes, for example, a recombinant DNA which is incorporated into a vector; into an autonomously replicating plasmid or virus; or into the genomic DNA of a prokaryote or eukaryote, or which exists as a separate molecule (e.g. , a cDNA or a genomic DNA fragment produced by PCR or restriction endonuclease treatment) independent of other sequences. It also includes a recombinant DNA which is part of a hybrid gene encoding additional polypeptide sequence. By "substantially identical" is meant an amino acid sequence which differs only by conservative amino acid substitutions, for example, substitution of one amino acid for another of the same class (e.g., valine for glycine, arginine for lysine, etc.) or by one or more non-conservative substitutions, deletions, or insertions located at positions of the amino acid sequence which do not destroy the function of the protein (assayed, e.g., as described herein) . Preferably, such a sequence is at least 80%, more preferably 90%, and most preferably 95% homologous to one of the sequences of Figs. 2-28 (SEQ ID NOS: 1, 3, 6-30). A "substantially identical" nucleic acid sequence codes for a substantially identical amino acid sequence as defined above. By "transformed cell" is meant a cell into which (or into an ancestor of which) has been introduced, by means of recombinant DNA techniques, a DNA molecule encoding (as used herein) a TR-interacting protein. By "positioned for expression" is meant that the DNA molecule is positioned adjacent to a DNA sequence which directs transcription and translation of the sequence (i.e., facilitates the production of, e.g., a TR-interacting protein) . By "purified antibody" is meant antibody which is at least 60%, by weight, free from the proteins and naturally-occurring organic molecules with which it is naturally associated. Preferably, the preparation is at least 75%, more preferably at least 90%, and most preferably at least 99%, by weight, antibody, e.g., TR- interacting protein-specific antibody. A purified TR- interacting protein antibody may be obtained, for example, by affinity chromatography using recombinantly- produced TR-interacting protein and standard techniques. By "specifically binds" is meant an antibody which recognizes and binds TR-interacting protein but which does not substantially recognize and bind other molecules in a sample, e.g., a biological sample, which naturally includes TR-interacting protein. Other features and advantages of the invention will be apparent from the following detailed description thereof, and from the claims. Brief Description of the Drawings The drawings are first briefly described. FIG. 1 shows a genetic selection in yeast for the isolation of TR-interacting protein-encoding cDNAs. The LexA/TR3 chimeras bind to the lexA binding site (lexA op) upstream of the LEU2 gene. (A) In cells expressing a fusion protein consisting of the B42 transactivation (TA) domain fused to a protein that does not interact specifically with the lexA/TR chimera, the LEU2 gene is not expressed, and the cells require supplemental leucine for growth. (B) In cells expressing a TA fusion to a protein capable of binding the lexA/TR chimera, the TA domain is brought specifically to the promoter LEU2 expression is increased, and the cells do not require supplemental leucine. FIG. 2 shows the complete amino acid sequence of JL1 (SEQ ID N0:1), aligned with the recently identified S . cerevisiae transcriptional coactivator SUG1 (Swaffield et al.. Nature 357:698-700, 1992) (SEQ ID NO:2). Identities and conservative substitutions are indicated. The overall sequence identity is 73%. The boxed and bold residues from 190 to 197 (JL1) represent a potential ATP binding site that is conserved in all members of this family. The boxed residues from 45 to 66 (JL1) are a putative leucine zipper, extended by 1 heptad toward the N-terminus in this full length sequence, which appears to be unique to JL1 and SUG1. The N-terminal portion of the JL1 sequence (1-49) was derived from subcloned PCR products corresponding to the 5' end of the JL1 mRNA. Independent clones with identical sequence were isolated using internal JL1 and vector primers with a HeLa cell cDNA library as template. The methionine residue assigned as the start codon is preceded by a stop codon only 9 nucleotides upstream. FIG. 3 shows (A) the amino acid sequence of JL2 (SEQ ID NO:3); the two LIM domains are underlined and the consensus C/D and H residues are bold. This sequence represents the human portion of the fusion protein isolated as an activator of the lexA/TR/3 chimera. (B) shows the alignment of the LIM domains of JL2 (SEQ ID NO:4) with those of Linll (SEQ ID N0:5). These domains in both proteins include matches to all consensus positions; the overall sequence identity is 35%.

FIG. 27 (SEQ ID NO:29) shows a partial nucleic acid sequence and deduced amino acid seguence of the TR- interacting protein SllOa-. FIG. 28 (SEQ ID NO:30) shows a partial nucleic acid sequence and deduced amino acid sequence of the TR- interacting protein S243b. FIG. 29 shows a Northern analysis of JL1 and JL2 expression in various human tissues. Specifically, 2 jug of poly A + mRNA from the indicated tissues (H, heart; B, brain; Pi, placenta; Lu, lung; Li, liver; SM, skeletal muscle; K, kidney; Pa, pancreas; all obtained from Clontech, Palo Alto, CA) was hybridized to JL1 and JL2 probes by standard techniques and washed at high stringency (see Ausubel et al., infra). Equivalent loading of RNA was verified by hybridization with a human actin cDNA probe. There now follows a description of the use of an in vivo interaction trap system for the isolation of proteins which physically associate with thyroid hormone receptor and a description of exemplary interacting proteins (termed, TR-interacting proteins) . This system may be used generally to isolate proteins which interact with any nuclear hormone receptor. Because the system has such general application for the isolation of nuclear hormone receptor-interacting proteins, this example is designed to illustrate, not limit, the invention. Detailed Description Applicants have used an in vivo interaction trap system (developed in the laboratory of Dr. Roger Brent) to identify and isolate proteins that physically interact with nuclear hormone receptors and, in particular, with the ligand binding domain of the rat receptor TR/3. This system, based on the modular nature of transcription factors, allows direct genetic selection for proteins capable of interacting with a desired protein. In general, DNA encoding the desired protein is fused to DNA encoding the C-terminus of a DNA binding domain, for example, the DNA binding domain of the bacterial repressor LexA protein, to generate a chimeric transcription factor, which can be tested for function in yeast. In the instant case, a lexA/TR chimera consisting of intact lexA fused to the hinge, ligand binding, and C terminal (D, E and F) domains of TRβ was found to be completely unable to activate transcription in either the presence or absence of T3 ligand. This lack of transcriptional activation by the lexA/TR chimera provided the basis for applicants 7 genetic selection. As shown in Fig. 1, a yeast strain in which expression of the LEU2 gene is dependent on binding of an activator to upstream lexA binding sites (i.e., operators) is unable to grow in the absence of added leucine when this chimera is expressed. However, if such a strain expresses a second chimeric protein which includes a relatively weak transcriptional activation domain (e.g., the B42 activation domain of Ma and Ptashne, Cell 51:113, 1987) fused to a protein capable of interacting specifically with lexA/TR, LEU2 gene expression is activated, and leucine is not required for growth. Using this system, a number of proteins which interact with thyroid hormone receptor were isolated as follows. A plasmid cDNA library was produced by standard techniques from HeLa cell mRNA and had approximately 10 6 original members. Each of these cDNA inserts was fused to the B42 transcriptional activation domain (Ma and Ptashne, Cell 51:113, 1987), and expression of the fusion protein was placed under the control of the inducible yeast GAL10 promoter. In addition to the B42 activating domain, this expression construct also carried, amino to carboxy terminal, an ATG for protein expression, an optional nuclear localization sequence, and an optional epitope tag for rapid immunological detection of fusion protein synthesis. The plasmid also included replication origins for yeast and E. coli as well as selectable markers for both. The fusion protein library was introduced into a yeast strain that expressed the lexA/TR/3 chimera and also contained two reporter genes: a lexAop/LEU2 selection construct and a lexAop/3-galactosidase indicator construct. Approximately 10 7 initial transformants were generated under nonselective conditions, representing a several fold redundancy relative to the original number of clones in the library. These transformants were recovered and replated under selective (leu " ) conditions in the presence or absence of thyroid hormone; based on the results of a functional analysis of intact TRs in yeast (Privalsky et al.. Cell 63:1277-1286, 1990), a high concentration of triac (10 ~5 M) was added directly to the plates. A number of leucine-independent colonies that contained candidate TR-interacting cDNAs were obtained under both conditions. The specificity of an interaction between TR and a candidate TR-interacting protein can be checked in several ways. For example, clones which do not activate expression of the lexA/9-galactosidase construct can be eliminated. These clones generally include yeast mutants that activate the LEU2 promoter or mammalian cDNAs that activate by some means other than through the lexA binding sites. Since the expression of the cDNA library fusion protein is under the control of an inducible promoter, the dependence of reporter gene expression on this chimera can also be tested by this criterion. cDNA library plasmids were recovered from those yeast strains which passed the above tests. Each was reintroduced into the original lexA/TR strain, and their ability to specifically activate expression was confirmed. This step was included because yeast transformants frequently contain one or more plasmids, in addition to the one that allows survival under the selective conditions. To confirm their specificity for TR3 interaction, the rescued plasmids were also introduced into strains containing other lexA chimeras generated in Dr. Brent's laboratory; these included lexA/myc and lexA/cdc2. All of the clones were found to be specific for TR3 by this criterion. cDNA clones that passed all of the above tests were concluded to encode proteins that could specifically interact with the lexA/TR chimera. Based on restriction mapping, these clones were sorted into distinct classes. Members of each class were sequenced across the fusion junction with the transcriptional activation domain. Sequences of many of these proteins are shown in Figs. 2-28 (SEQ ID NOS: 1, 3, 6-30) . Although some clones have shown no significant similarities in searches of the sequence databases, most have shown some relationship to known proteins. As described below, two classes showed strong matches over limited domains to nuclear transcription factors. One clone unexpectedly appeared to encode a fragment of the human clathrin heavy chain. Since cell biology considerations argue that TR/3 is quite unlikely to have a biologically relevant interaction with clathrin in mammalian cells, it can be assumed that the sensitivity of the selection system allows isolation of fragments of proteins that show some affinity for TR based solely on simple chemical interactions. Interacting proteins of this sort are useful for the production of peptides which interfere with thyroid hormone receptor function (see below) . Because RXR/3 interacts with TR and is expressed in HeLa cells (Lied et al.. Cell 68:377-395, 1992), RXR fusions would be expected to activate reporter gene expression and be isolated in this selection. To test this prediction, a fragment encoding the RXRα hinge and ligand binding domains was inserted in frame into the transcriptional activation domain fusion vector used to generate the original cDNA library. As expected, this RXR fusion construct allowed the lexA/TR tester strain, but not strains expressing other lexA chimeras, to survive in the absence of leucine and also activated expression of the lexA/j3-galactosidase reporter gene (see Table 2) . RXR, however, was not identified in the original screen. This is most likely explained by the fact that, although the original library was large, it was extensively amplified, which can decrease representation of rare cDNAs. Moreover, the fusion to the transcriptional activation domain must be in the correct frame and may be functional if the fusion occurs in only a relatively limited number of positions. Since members of the nuclear hormone receptor superfamily are generally expressed at extremely low levels, it is most likely that appropriate RXR clones were simply not present in the amplified library originally screened. Unexpectedly, nearly all of the lexA/TR interacting cDNAs showed very strong dependence on hormone for activation. Two proteins, JL1 and JL2, which were isolated in the initial selection in the presence of triac, both interacted with the lexA/TR chimera much more strongly when triac was present, as judged by level of expression of 3-galactosidase. This hormone + group constituted the majority of isolated clones (>10 different classes) , although there were a smaller number in a hormone " group that interacted only when triac was absent. These classes are shown in Table 1.

Chem. 267:618- 623, 1992) 110a-; no significant homology to any known gene in current databank The fact that virtually all of the isolated clones were specific for one hormone state or the other was surprising. The genetic properties of sample TR-interacting proteins and RXR fusion proteins are summarized in Table 2. TABLE 2 Lex A fusion TA fusion lexA lexA/TR lexA/c-mvc B42 (vector) -T3 leu " ,W leu " ,W leu~,W +T3 JL1/JL2 leu " ,W leu",W leu + ,B RXR leu + ,B leu~,W leu + ,B II Each of the strains shown in Table 2 contained both the lexAop/LEU2 and the lexAop/3-galactosidase reporter constructs, along with the indicated transcriptional activation (TA) domain fusion proteins; the cDNA cloning vector expressed the B42 transcriptional activation domain alone (Ma and Ptashne, Cell 51:113-119, 1987) . Cells containing the indicated TA fusion proteins were transformed with each of the indicated lexA fusion vectors, and phenotypes were tested under various conditions. +/-T3 indicates the presence or absence of 10~ 5 M triac in the plates (Privalsky et al., Cell 63:1277-1286, 1990); leu"/ + denotes the ability of the transformed cells to grow on plates lacking leucine; W/B indicates formation of white or blue colonies on indicator plates containing the indicator X-gal. As expected, the activation conferred by the JLl, JL2, and RXR fusion proteins was dependent on the specific induction of the GAL10 promoter that controls their expression. The largest class of lexA/TR interacting cDNAs (17 individual isolates) encoded JLl. All of the members of the class exhibited the properties summarized above, although some variations in the levels of expression of 3-galactosidase in the presence or absence of hormone was observed for clones that varied in position of the junction to the B42 transactivation domain. JLl is quite similar to several previously identified proteins, particularly TBP1, as indicated in Fig. 2. The functions of this family of proteins are diverse: TBP1 is a nuclear protein that has a poorly understood but apparently important role in transcriptional regulation of HIV (Nelbock et al., Science 248:1650-1653, 1990), while the mammalian protein VCP (Roller and Brownstein, Nature 325:542-545, 1987) and its apparent yeast homolog CDC48 (Frohlich et al., J. Cell. Biol. 114:443-453, 1991) are cytoplasmic proteins of unknown function. TBP1 was isolated by using labeled HIV TAT protein to screen a lambda gtll expression library and has been found to interact directly with that important viral regulator but not with DNA. Although initially described as an inhibitor of TAT function in cotransfections, a more recent report indicates that TBP1 may act to stimulate TAT activity and may have a direct transcriptional activation function in its own right (Rosen, Abstract. Cold Spring Harbor Symp. Quant. Biol. 57:267, 1992). On these grounds, TBP could be considered a candidate transcriptional coactivator. JLl is even more homologous to SUGl (see Fig. 2) , a yeast gene recently isolated as a suppressor of a defective version of the GAL4 activator (Swaffield et al., Nature 357:698, 1992). By genetic analysis, SUGl appears to be a coactivator capable of specifically interacting with GAL4, supporting the hypothesis that JLl similarly encodes a coactivator protein. JL2, encoded by a single recovered cDNA, includes two copies of the LIM domain originally identified as a conserved motif in three putative transcription factors: Lin-ll (Freyd et al. , Nature 344:876-879, 1990), Isl-1 (Karlsson et al., Nature 344:879-882, 1990) and Mec-3 (Way, and Chalfie, Cell 54:5-16, 1988). In the context of endocrine control of gene expression, isl-1 is particularly interesting since it is an activator of the insulin enhancer. It is expressed in both developing and mature islet cells and is thought to be involved in the initial differentiation of the islet cells, in addition to its presumed role in regulating insulin expression. Isl-1 is also expressed in a subset of neurons in the adult and, quite recently, it has been shown to be expressed at very early stages of embryonic motor neuron differentiation. The pattern of this early expression suggests that isl-1 may play a primary role in the initial determination of motor neuron cell fate in response to inductive signals from the notochord and floor plate (Ericson et al.. Science 256:155-1560, 1992). Consistent with this possibility, lin-11 and mec-3 are both C. elegans developmental regulators, associated with cell lineage determination in mechanosensory neurons and a vulval precursor cell, respectively. Lin-11, isl-1, and mec-3 contain a homeobox-type DNA binding domain in addition to two copies of the LIM domain, as do other recently identified members of this family (see, e.g., Cohen et al.. Genes & Dev. 6:715-729, 1992; Taira et al., Genes & Dev. 6:356-366, 1992). However, a homeodomain is absent in a three related LIM domain-containing proteins called rhombotins 1-3, at least two of which are the products of putative oncogenes (Rosen, Abstract. Cold Spring Harbor Symp. Quant. Biol. 57:267, 1992). The LIM domain consensus sequence contains conserved cysteine and histidine residues, and it has recently been demonstrated that at least the lin- 11 version binds metal ions (2 atoms of Zn and 4 of Fe; Li et al., Proc. Natl. Acad. Sci. USA 88:9210, 1991). As indicated in Fig. 3, JL2 has a good match with the LIM consensus in lin-11; it does not, however, include a homeobox. In this regard, JL2 appears to be more like the rhombotins than it is like the transcription factors lin-11, isl-1, and mec-3. An initial determination of the pattern of expression of JLl and JL2 has begun. As indicated in Fig. 29, the approximately 2.1 kb JLl mRNA is expressed at various levels in all the human tissues examined. The slightly smaller 1.8 kb JL2 mRNA is expressed in a somewhat narrower range of tissues. Based on the amount of time required to visualize the bands, both mRNAs are present at very low levels, consistent with a regulatory role. As judged by exposure time, the JLl mRNA appears to be expressed at an approximately 6 fold higher level than that of JL2, as would be expected from the higher number of JLl clones isolated. To determine whether a TR-interacting protein has a positive or a negative effect on TR function, cotransfections of the TR-interacting protein expression vector and a TR3 or TRα expression vector are carried out by standard techniques, preferably, in a host cell line that does not express significant levels of the TR- interacting protein (see, e.g., Ausubel et al. , Current Protocols in Molecular Biology. John Wiley & Sons, 1989) . A TR-interacting protein which acts as a positive regulator (e.g., a coactivator), is indicated by increased TR activity in such an assay. Conversely, a TR-interacting protein which acts as a negative regulator is indicated by reduced TR activity. Cotransfection assays of this sort are generally described in Ausubel et al. (supra) . In one particular example, the TR-interacting protein-encoding cDNA is inserted into the CDM8 vector (Seed, B. , Nature 329:840, 1987), and increasing doses of this plasmid are cotransfected with a TR3 expression vector (Brent et al., J. Biol. Chem. 264:178, 1989) plus one of several different reporter genes containing various T3REs linked, e.g., to the herpes virus thymidine kinase (TK) gene (Brent supra) . In these transfections, the level of total expression vector is maintained at a constant level by addition of CDM8, as necessary. To control for variations in transfection efficiency and for effects of the TR-interacting protein on the TK promoter, transfections also include pTKGH (Selden et al., Moll. Cell. Biol. 6:3173, 1986), a plasmid which directs expression of human growth hormone under the control of the same TK promoter. As controls for regulatory effects, Pit-1, c-fos and c-jun may also be cotransfected with TR/3 and the T3RE reporters. Since the relative and absolute levels of expression of TR/3 and its potential partners may be crucial for observation of any effect, a negative result is first confirmed at a variety of doses of each vector. Several cell lines are also examined. If however, no evidence for a specific effect of a TR-interacting protein on TR function is observed after these steps, it will be concluded that the interaction with TR/3 is likely to be an artifact of the sensitivity of the genetic selection originally used to isolate them. If, on the other hand, the TR-interacting protein alters TR function, the specificity of the effect is examined. Simple cotransfections of the TR-interacting protein expression vector with RSVCAT or TKCAT vectors is used to confirm that any negative effect is not a consequence of squelching (Ptashne and Gann, Nature 346:329-331, 1990). Cotransfections of appropriate reporters with the TR-interacting protein expression vectors plus vectors expressing TRα, the RARs, VDR, GR, ER or others may also be carried out. The portions of any particular TR-interacting protein required for functional interaction may be determined initially by standard deletion analysis, with mutant proteins tested by the above cotransfection assay. The results of such mapping may be confirmed and extended by testing the effect of the same mutations on the lexA/TR dependent activation of expression in yeast, and by the following biochemical interaction assays. To determine directly whether a TR-interacting protein can interact with thyroid hormone receptor, antiserum directed against one of the potential partners is tested for its ability to coimmunoprecipitate the other. This may be assayed directly using bacterially- produced TR proteins and antiserum or monoclonal antibodies that recognize some region of the TR/3 protein. In one particular example of such an assay, in vitro translated, 35 S labeled TR-interacting protein is mixed with TR/3 protein in the presence or absence of T3, and the mixture is immunoprecipitated with an antiserum that recognizes the N-terminus of the TR. Similarly labeled RXR/3 protein, which is known to interact strongly with TR / 3 in such procedures, is used as a positive control. The immunoprecipitated material is resolved by SDS PAGE, and the presence of the TR-interacting protein or RXR in such immunoprecipitates is assessed by autoradiography. The observation of T3-dependent coimmunoprecipitation of the potential TR binding proteins with the TR provides strong evidence for a direct interaction with the receptor. A general description of in vitro translation of proteins is described in Hope and Struhl, Cell 43:177- 188, 1985. Labelling proteins with 35 S, production of antibodies (including monoclonal antibodies) , and immunoprecipitation procedures are described in Ausubel (infra) . Lack of such a coimmunoprecipitation may suggest that the interaction of a particular protein with TR is too transient to be detected by this approach. This can be tested by addition of various crosslinking reagents to the binding reactions, as described in the analysis of the interactions of GR with AP-1, for example (Yang-Yen et al., Cell 62:1205-1215, 1990). It is important to control for the variety of artifactual associations that may complicate interpretation of such studies. If crosslinking does not reveal an interaction between a TR- interacting protein and TR/3, even in the presence of extracts that might supply additional cofactors required, it may be that their interaction in yeast is artifactual. Truncated versions of TR-interacting proteins can also be tested using this method to identify specific portions of each protein required for TR interaction. This is of particular importance from the point of view of potential pharmacologic intervention with the interaction, since such fragments may facilitate the production of specific inhibitors of TR function. TR-Interactinq Proteins and Antibodies Polypeptide Expression In general, polypeptides according to the invention may be produced by transformation of a suitable host cell with all or part of a TR-interacting protein- encoding cDNA fragment (e.g., the cDNA described above) in a suitable expression vehicle. Those skilled in the field of molecular biology will understand that any of a wide variety of expression systems may be used to provide the recombinant protein. The precise host cell used is not critical to the invention. The TR-interacting protein may be produced in a prokaryotic host (e.g., E. coli) or in a eukaryotic host (e.g., Saccharomyces cerevisiae or mammalian cells, e.g., COS 1, NIH 3T3, or HeLa cells). Such cells are available from a wide range of sources (e.g., the American Type Culture Collection, Rockland, MD; also, see, e.g., Ausubel et al. , Current Protocols in Molecular Biology, John Wiley & Sons, New York, 1989) . The method of transformation or transfection and the choice of expression vehicle will depend on the host system selected. Transformation and transfection methods are described, e.g., in Ausubel et al. (Current Protocols in Molecular Biology, John Wiley & Sons, New York, 1989) ; expression vehicles may be chosen from those provided, e.g., in Cloning Vectors : A Laboratory Manual (P.H. Pouwels et al., 1985, Supp. 1987). One preferred expression system is the mouse 3T3 fibroblast host cell transfected with a pMAMneo expression vector (Clontech, Palo Alto, CA) . pMAMneo provides: an RSV-LTR enhancer linked to a dexamethasone- inducible MMTV-LTR promotor, an SV40 origin of replication which allows replication in mammalian systems, a selectable neomycin gene, and SV40 splicing and polyadenylation sites. DNA encoding a TR-interacting protein would be inserted into the pMAMneo vector in an orientation designed to allow expression. The recombinant TR-interacting protein would be isolated as described below. Other preferable host cells which may be used in conjunction with the pMAMneo expression vehicle include COS cells and CHO cells (ATCC Accession Nos. CRL 1650 and CCL 61, respectively) . Alternatively, a TR-interacting protein is produced by a stably-transfected mammalian cell line. A number of vectors suitable for stable transfection of mammalian cells are available to the public, e.g., see Pouwels et al. (supra) ; methods for constructing such cell lines are also publicly available, e.g., in Ausubel et al. (supra) . In one example, cDNA encoding the TR- interacting protein is cloned into an expression vector which includes the dihydrofolate reductase (DHFR) gene. Integration of the plasmid and, therefore, the TR- interacting protein-encoding gene into the host cell chromosome is selected for by inclusion of 0.01-300 /tiM methotrexate in the cell culture medium (as described in Ausubel et al. , supra) . This dominant selection can be accomplished in most cell types. Recombinant protein expression can be increased by DHFR-mediated amplification of the transfected gene. Methods for selecting cell lines bearing gene amplifications are described in Ausubel et al. (supra) ; such methods generally involve extended culture in medium containing gradually increasing levels of methotrexate. DHFR-containing expression vectors commonly used for this purpose include pCVSEII-DHRF and pAdD26SV(A) (described in Ausubel et al., supra) . Any of the host cells described above or, preferably, a DHFR-deficient CHO cell line (e.g., CHO DHFR ~ cells, ATCC Accession No. CRL 9096) are among the host cells preferred for DHFR selection of a stably-transfected cell line or DHFR-mediated gene amplification. Once the recombinant TR-interacting protein is expressed, it is isolated, e.g., using affinity chromatography. In one example, an anti-TR-interacting protein antibody (e.g., produced as described herein) may be attached to a column and used to isolate the TR- interacting protein. Lysis and fractionation of TR- interacting protein-harboring cells prior to affinity chromatography may be performed by standard methods (see, e.g., Ausubel et al., supra) . Alternatively, a TR- interacting protein fusion protein, for example, a TR- interacting protein-maltose binding protein, a TR- interacting protein-/3-galactosidase, or a TR-interacting protein-trpE fusion protein, may be constructed and used for TR-interacting protein isolation (see, e.g., Ausubel et al., supra; New England Biolabs, Beverly, MA). Once isolated, the recombinant protein can, if desired, be further purified, e.g., by high performance liquid chromatography (see, e.g., Fisher, Laboratory Techniques In Biochemistry And Molecular Biology, eds., Work and Burdon, Elsevier, 1980) . Polypeptides of the invention, particularly short TR-interacting protein fragments, can also be produced by chemical synthesis (e.g., by the methods described in Solid Phase Peptide Synthesis , 2nd ed. , 1984 The Pierce Chemical Co., Rockford, IL) . These general techniques of polypeptide expression and purification can also be used to produce and isolate useful TR-interacting protein fragments or analogs (described herein) . Anti-TR-Interacting Protein Antibodies Human TR-interacting protein (or immunogenic fragments or analogues) may be used to raise antibodies useful in the invention; such polypeptides may be produced by recombinant or peptide synthetic techniques (see, e.g.. Solid Phase Peptide Synthesis , supra; Ausubel et al. , supra) . The peptides may be coupled to a carrier protein, such as KLH as described in Ausubel et al, supra. The KLH-peptide is mixed with Freund's adjuvant and injected into guinea pigs, rats, or preferably rabbits. Antibodies may be purified by peptide antigen affinity chromatography. Monoclonal antibodies may also be prepared using the TR-interacting proteins described above and standard hybridoma technology (see, e.g., Kohler et al.. Nature 256:495, 1975; Kohler et al. , Eur. J. Immunol . .6:511, 1976; Kohler et al., .Eur. J. Immunol . 6:292, 1976; Hammerling et al.. In Monoclonal Antibodies and T Cell Hybridomas , Elsevier, NY, 1981; Ausubel et al., supra) . Once produced, polyclonal or monoclonal antibodies are tested for specific TR-interacting protein recognition by Western blot or immunoprecipitation analysis (by the methods described in Ausubel et al. , supra) . Antibodies which specifically recognize a TR- interacting protein are considered to be useful in the invention; such antibodies may be used, e.g., in an immunoassay to monitor the level of TR-interacting protein produced by a mammal or to determine the subcellular location of any of these thyroid hormone receptor modulatory proteins. Preferably, antibodies of the invention are produced using fragments of the TR-interacting protein which lie outside highly conserved regions and appear likely to be antigenic, by criteria such as high frequency of charged residues. In one specific example, such fragments are generated by standard techniques of PCR and cloned into the pGEX expression vector (Ausubel, F.M. et al.. Current Protocols in Molecular Biology (Greene Pub. Assoc, New York, 1992). Fusion proteins are expressed in E. coli and purified using a glutathione agarose affinity matrix as described in (Ausubel, F.M. et al.. Current Protocols in Molecular Biology (Greene Pub. Assoc, New York, 1992)). To attempt to minimize the potential problems of low affinity or specificity of antisera, two or three such fusions are generated for each protein, and each fusion is injected into two rabbits. Antisera are raised by injections in a series including at least three booster injections. This approach has been successfully used by applicants to generate antibodies capable of discriminating between the different TR isoforms. Antisera is cleared of anti-GST antibodies using GST immobilized on a glutathione column, and the antisera are checked by ELISA for titer and specificity, using GST fusion proteins as controls. Antisera is also checked for its ability to immunoprecipitate in vitro translated TR-interacting proteins or control proteins, such as Pit- 1 or RARα. Western blots of total or nuclear vs. cytoplasmic fractionated HeLa cell proteins are also probed with the antisera to assess specificity and to characterize subcellular compartmentalization. In these and other immunologic assays, specificity is confirmed by the specific competition with the GST fusion protein. Once the specificity of an antiserum is confirmed, it may be used in any standard indirect immunofluorescence procedure to determine the subcellular distribution of the TR-interacting protein in a particular cell type. Based on their similarity to nuclear transcriptional regulators and their interaction with TRs, TR-interacting proteins are likely to be nuclear localized. Use The proteins described herein interact with thyroid hormone receptor and are thus likely to mediate or modulate TR function. Because of their effects on thyroid receptor activity, such proteins (or peptides derived from these proteins, particularly, short peptides which are capable of TR interaction) , may facilitate the production of pharmacologic modifiers of receptor function. In particular, TR-interacting proteins of the invention which positively regulate TR function in vivo or m vitro (e.g., as assayed in cotransfections as described above) may be used to produce therapeutic peptides which include a TR interaction domain but which lack a TR activity-enhancing domain, for example, a domain which interacts with the transcriptional apparatus; the efficacy of such peptides may also, e.g., as assayed as described above. Such peptides would bind TR, interfering with receptor binding by the native TR- interacting protein, and thereby reducing TR activity. Peptides of this sort would be useful in the treatment of hyperthyroidism. Conversely, interacting peptides derived from TR- interacting proteins which negatively regulate TR function, as assayed in vivo or in vitro (again, e.g., by the assays described above) may be used to produce therapeutic peptides which block the normal interaction between the receptor and the negatively acting TR- interacting protein. These peptides may similarly be administered to a mammal to treat thyroid disorders. Such therapeutic polypeptides of the invention may be administered by any appropriate route, e.g., intravenously, at a dosage which is effective to increase or decrease thyroid function. Treatment may be repeated as necessary for alleviation of disease symptoms. The polypeptides of the invention are also useful for identifying those compartments of mammalian cells which contain proteins important to the function of the thyroid hormone receptor. Antibodies specific for a particular TR-interacting protein (or any nuclear hormone receptor-interacting protein) may be produced as described above. The normal subcellular location of the protein is then determined either .in situ or using fractionated cells by any standard immunological or immunohistochemical procedure (see, e.g., Ausubel et al., supra; Bancroft and Stevens, Theory and Practice of Histological Techniques. Churchill Livingstone, 1982) . Antibodies specific for TR-interacting proteins also find diagnostic use in the detection or monitoring of thyroid disorders. Levels of a TR-interacting protein in a sample may be assayed by any standard technique. For example, its expression may be monitored by standard Northern blot analysis or may be aided by PCR (see, e.g., Ausubel et al., supra; PCR Technology: Principles and Applications for DNA Amplification, ed. , H.A. Ehrlich, Stcokton Press, NY) . These techniques are enabled by the provision of the TR-interacting protein sequences described herein. Alternatively, standard immunological or immunohistochemical procedures (e.g., those described above) may also be used with the antibodies described herein for TR-interacting protein detection. Other Embodiments In other embodiments, the invention includes any protein which is substantially homologous to a human TR¬ interacting protein (Figs. 2-28, SEQ ID NOS: 1, 3, 6-30); such homologs include other substantially pure naturally occurring mammalian TR-interacting protein proteins as well as allelic variants; natural mutants; induced mutants; proteins encoded by DNA that hybridizes to the TR-interacting protein sequence of any of Figs. 2-28 (SEQ ID NOS: 1, 3, 6-30) under high stringency conditions or low stringency conditions (e.g., washing at 2X SSC at 40°C with a probe length of at least 40 nucleotides) ; and polypeptides or proteins specifically bound by antisera directed to a TR-interacting protein, especially by antisera to the TR binding domain of the TR-interacting protein. The term also includes chimeric polypeptides that include a TR-interacting protein fragment. The invention further includes analogs of any naturally occurring TR-interacting protein. Analogs can differ from the naturally occurring TR-interacting protein by amino acid sequence differences, by post- translational modifications, or by both. Analogs of the invention will generally exhibit at least 80%, more preferably 90%, and most preferably 95% or even 99%, homology with all or part of a naturally occurring TR- interacting protein sequence. The length of comparison sequences will be at least 8 amino acid residues, preferably at least 24 amino acid residues, and more preferably more than 35 amino acid residues. Modifications include in vivo and in vitro chemical derivatization of polypeptides, e.g., acetylation, carboxylation, phosphorylation, or glycosylation; such modifications may occur during polypeptide synthesis or processing or following treatment with isolated modifying enzymes. Analogs can also differ from the naturally occurring TR-interacting protein by alterations in primary sequence. These include genetic variants, both natural and induced (for example, resulting from random mutagenesis by irradiation or exposure to ethanemethylsulfate or by site-specific mutagenesis as described in Sambrook, Fritsch and Maniatis, Molecular Cloning: A Laboratory Manual (2d ed.), CSH Press, 1989, hereby incorporated by reference; or Ausubel et al.. Current Protocols in Molecular Biology. John Wiley & Sons, 1989, hereby incorporated by reference). Also included are cyclized peptides molecules and analogs which contain residues other than L-amino acids, e.g., D- amino acids or non-naturally occurring or synthetic amino acids, e.g., β or γ amino acids. In addition to full-length polypeptides, the invention also includes TR-interacting protein fragments. As used herein, the term "fragment", means at least 10 contiguous amino acids, preferably at least 30 contiguous amino acids, more preferably at least 50 contiguous amino acids, and most preferably at least 60 to 80 or more contiguous amino acids. Fragments of TR-interacting proteins can be generated by methods known to those skilled in the art or may result from normal protein processing (e.g., removal of amino acids from the nascent polypeptide that are not required for biological activity or removal of amino acids by alternative mRNA splicing or alternative protein processing events) . Preferable fragments or analogs according to the invention are those which facilitate interaction of the peptide with a thyroid hormone receptor.

Claims: Claims 1. A method for determining whether a test protein is capable of interacting with a nuclear hormone receptor protein, comprising: (a) providing a host cell which contains (i) a reporter gene operably linked to a protein binding site; (ii) a first fusion gene which expresses a first fusion protein, said first fusion protein comprising a nuclear hormone receptor protein covalently bonded to a binding moiety which is capable of specifically binding to said protein binding site; and (iii) a second fusion gene which expresses a second fusion protein, said second fusion protein comprising said test protein covalently bonded to a weak gene activating moiety; and (b) determining whether said test protein increases expression of said reporter gene as an indication of its ability to interact with said nuclear hormone receptor protein. 2. The method of claim 1, wherein said method further comprises treating said host cell with a ligand which binds said nuclear hormone receptor and identifying a hormone-dependent interacting protein by its ability to increase expression of said reporter gene only upon treatment of said cell by said ligand. 3. The method of claim 1, wherein said method further comprises treating said host cell with a ligand which binds said nuclear hormone receptor and identifying a hormone-independent interacting protein by its ability to increase expression of said reporter gene both in the presence and in the absence of said ligand treatment. 4. The method of claim 1, wherein said method further comprises treating said host cell with a ligand which binds said nuclear hormone receptor and identifying a ligand-sensitive interacting protein by its ability to increase expression of said reporter gene in the absence but not in the presence of said ligand treatment. 5. The method of claim 1, wherein said weak gene activating moiety is the gene activating moiety of B42. 6. The method of claim 1, wherein said nuclear hormone receptor is a thyroid hormone receptor. 7. The method of claims 2 or 3, wherein said ligand is a thyroid hormone. 8. A substantially pure TR-interacting protein. 9. The polypeptide of claim 8, comprising an amino acid sequence substantially identical to the amino acid sequence of JLl shown in Figure 2 (SEQ ID NO: 1) . 10. The polypeptide of claim 8, comprising an amino acid sequence substantially identical to the amino acid sequence of JL3 shown in Figure 3 (SEQ ID NO: 3) . 11.
