HUMAN DNA MISMATCH REPAIR PROTEINS

Abstract: The present invention discloses three human DNA repair proteins and DNA (RNA) encoding such proteins and a procedure for producing such proteins by recombinant techniques. One of the human DNA repair proteins, hMLH1, has been mapped to chromosome 3 while hMLH2 has been mapped to chromosome 2 and hMLH3 has been mapped to chromosome 7. The invention provides methods to diagnose alterations in the hMLH1, hMLH2 and hMLH3 genes.

Description: HUMAN DNA MISMATCH REPAIR PROTEINS This invention relates to newly identified polynucleotides, polypeptides encoded by such polynucleotides, the use of such polynucleotides and polypeptides, as well as the production of such polynucleotides and polypeptides. More particularly, the polypeptides of the present invention are human homologs of the prokaryotic mutL4 gene and are hereinafter referred to as hMLHl, hMLH2 and hMLH3. In both prolaryotes and eukaryotes, the DNA mismatch repair gene plays a prominent role in the correction of errors made during DNA replication and genetic recombination. The E. coli methyl-directed DNA mismatch repair system is the best understood DNA mismatch repair system to date. In E. coli , this repair pathway involves the products of the mutator genes mutS, mutL, mutH, and uvrD. Mutants of any one of these genes will reveal a mutator phenotype. MutS is a DNA mismatch-binding protein which initiates this repair process, uvrD is a DNA helicase and MutH is a latent endonuclease that incises at the unmethylated strands of a hemi-methylated GATC sequence. MutL protein is believed to recognize and bind to the mis atch-DNA-MutS-MutH complex to enhance the endonuclease activity of MutH protein. After the unmethylated DNA strand is cut by the MutH, single-stranded DNA-binding protein, DNA polymerase III, exonuclease I and DNA ligase are required to complete this repair process (Modrich P., Annu. Rev. Genetics, 25:229-53 (1991)) . Elements of the E. coli MutLHS system appears to be conserved during evolution in prokaryotes and eukaryotes. Genetic study analysis suggests that Saccharomyces cerevisiae has a mismatch repair system similar to the bacterial MutLHS system. In S . cerevisiae, at least two MutL homologs, PMSl and MLHl , have been reported. Mutation of either one of them leads to a mitotic mutator phenotype (Prolla et al, Mol. Cell. Biol. 14:407-415 (1994)). At least three MutS homologs have been found in S . cerevisiae, namely MSH1 , MSH2 , and MSH3 . Disruption of the MSH2 gene affects nuclear mutation rates. Mutants in S . cerevisae , MSH2 , PMSl , and MLHl have been found to exhibit increased rates of expansion and contraction of dinucleotide repeat sequences (Strand et al. , Nature, 365:274-276 (1993) ) . It has been reported that a number of human tumors such as lung cancer, prostate cancer, ovarian cancer, breast cancer, colon cancer and stomach cancer show instability of repeated DNA sequences (Han et al. , Cancer, 53:5087-5089 (1993); Thibodeau et al. , Science 260:816-819 (1993); Risinger et al. , Cancer 53:5100-5103 (1993)). This phenomenon suggests that lack of the DNA mismatch repair is probably the cause of these tumors. Little was known about the DNA mismatch repair system in humans until recently, the human homolog of the MutS gene was cloned and found to be responsible for hereditary nonpolyposis colon cancer (HNPCC) , (Fishel et al. , Cell, 75:1027-1038 (1993) and Leach et al., Cell, 75:1215-1225 (1993)) . HNPCC was first linked to a locus at chromosome 2pl6 which causes dinucleotide instability. It was then demonstrated that a DNA mismatch repair protein (MutS) homolog was located at this locus, and that C-->T transitional mutations at several conserved regions were specifically observed in HNPCC patients. Hereditary nonpolyposiε colorectal cancer is one of the most common hereditable diseases of man, affecting as many as one in two hundred individuals in the western world. It has been demonstrated that hereditary colon cancer can result from mutations in several loci. Familial adenomatosis polyposis coli (APC) , linked to a gene on chromosome 5, is responsible for a small minority of hereditary colon cancer. Hereditary colon cancer is also associated with Gardner's syndrome, Turcot's syndrome, Peutz- Jaegherε syndrome and juvenile polyposis coli. In addition, hereditary nonpolyposis colon cancer may be involved in 5% of all human colon cancer. All of the different types of familial colon cancer have been shown to be transmitted by a dominant autosomal mode of inheritance. In addition to localization of HNPCC, to the short arm of chromosome 2, a second locus has been linked to a pre¬ disposition to HNPCC (Lindholm, et al. , Nature Genetics, 5:279-282 (1993)) . A strong linkage was demonstrated between a polymorphic marker on the short arm of chromosome 3 and the disease locus. This finding suggests that mutations on various DNA mismatch repair proteins probably play crucial roles in the development of human hereditary diseases and cancers. HNPCC is characterized clinically by an apparent autosomal dominantly inherited predisposition to cancer of the colon, endometrium and other organs. (Lynch, H.T. et al., Gastroenterology, 104:1535-1549 (1993)). The identification of markers at 2pl6 and 3p2l-22 which were linked to disease in selected HNPCC kindred unequivocally established its mendelian nature (Peltomaki, P. et al. , Science, 260:810-812 (1993)) . Tumors from HNPCC patients are characterized by widespread alterations of simple repeated sequences (microsatellites) (Aaltonen, L.A., et al. , Science, 260:812-816 (1993)). This type of genetic instability was originally observed in a subset (12 to 18% of sporadic colorectal cancers (Id. ) . Studies in bacteria and yeast indicated that a defect in DNA mismatch repair genes can result in a similar instability of microsatellites (Levinson, G. and Gutman, G.A. , Nuc. Acids Res. , 15:5325-5338 (1987)), and it was hypothesized that deficiency in mismatched repair was responsible for HNPCC (Strand, M. et al. , Nature, 365:274-276 (1993)) . Analysis of extracts from HNPCC tumor cell lines εhowed mismatch repair was indeed deficient, adding definitive support to this conjecture (Parsons, R.P., et al., Cell, 75:1227-1236 (1993)). As not all HNPCC kindred can be linked to the same loci, and as at least three genes can produce a similar phenotype in yeast, it seems likely that other mismatch repair genes could play a role in some cases of HNPCC. hMLHl is most homologous to the yeast mutL-homolog yMLHi while hMLH2 and hMLH3 have greater homology to the yeast mutL-homolog yPMSl (hMLH2 and hMLH3 due to their homology to yeast PMSl gene are sometimes referred to in the literature as hPMSl and hPMS2) . In addition to hMLHl, both the hMLH2 gene on chromosome 2q32 and the hMLH3 gene, on chromosome 7p22, were found to be mutated in the germ line of HNPCC patients. This doubles the number of genes implicated in HNPCC and may help explain the relatively high incidence of this disease. In accordance with one aspect of the present invention, there are provided novel putative mature polypeptides which are hMLHl, hMLH2 and hMLH3, as well as biologically active and diagnostically or therapeutically useful fragments, analogs and derivatives thereof. The polypeptides of the present invention are of human origin. In accordance with another aspect of the present invention, there are provided isolated nucleic acid molecules encoding such polypeptides, including mRNAs, DNAs, cDNAs, genomic DNA as well as biologically active and diagnostically or therapeutically useful fragments, analogs and derivatives thereof. In accordance with still another aspect of the present invention there are provided nucleic acid probes comprising nucleic acid molecules of sufficient length to specifically hybridize to hMLHl, hMLH2 and hMLH3 sequences. In accordance with yet a further aspect of the present invention, there is provided a process for producing such polypeptides by recombinant techniques which comprises culturing recombinant prokaryotic and/or eukaryotic host cells, containing an hMLHl, hMLH2 or hMLH3 nucleic acid sequence, under conditions promoting expression of said protein and subsequent recovery of said proteins. In accordance with yet a further aspect of the present invention, there is provided a process for utilizing such polypeptide, or polynucleotide encoding such polypeptide, for therapeutic purposes, for example, for the treatment of cancers.

Arrows indicate molecular weight in base pairs. In accordance with an aspect of the present invention, there are provided isolated nucleic acids (polynucleotides) which encode for the mature polypeptides having the deduced amino acid sequence of Figures l, 2 and 3 (SEQ ID No. 2, 4 and 6) or for the mature polypeptides encoded by the cDNA of the clone deposited aε ATCC Deposit No. 75649, 75651, 75650, deposited on January 25, 1994. ATCC Deposit No. 75649 is a cDNA clone which contains the full length sequence encoding the human DNA repair protein referred to herein as hMLHl; ATCC Deposit No. 75651 is a cDNA clone containing the full length cDNA sequence encoding the human DNA repair protein referred to herein as hMLH2; ATCC Deposit No. 75650 is a cDNA clone containing the full length DNA εequence referred to herein aε hMLH3. Polynucleotides encoding the polypeptides of the present invention may be obtained from one or more libraries prepared from heart, lung, prostate, spleen, liver, gallbladder, fetal brain and testeε tissues . The polynucleotides of hMLHl were discovered from a human gallbladder cDNA library. In addition, six cDNA clones which are identical to the hMLHl at the N-terminal ends were obtained from human cerebellum, eight-week embryo, fetal heart, HSC172 cells and Jurket cell cDNA librarieε . The hMLHl gene containε an open reading frame of 756 amino acids encoding for an 85kD protein which exhibits homology to the bacterial and yeast mutL proteins. However, the 5' non-tranεlated region waε obtained from the cDNA clone obtained from the fetal heart for the purpoεe of extending the non-tranεlated region to deεign the oligonucleotideε . The hMLH2 gene waε derived from a human T-cell lymphoma cDNA library. The hMLH2 cDNA clone identified an open reading frame of 2 , 796 base pairs flanked on both sides by in-frame termination codons. It is structurally related to the yeast PMSl family. It contains an open reading frame encoding a protein of 934 amino acid residues. The protein exhibits the highest degree of homology to yeast PMSl with 27% identity and 82 % similarity over the entire protein. A second region of significant homology among the three PMS related proteins is in the carboxyl terminus, between codons 800 to 900. This region shares a 22% and 47% homology between yeast PMSl protein and hMLH2 and hMLH3 proteins, respectively, while very little homology of thiε region waε obεerved between these proteins, and the other yeast mutL homolog, yMLHl. The hMLH3 gene waε derived from a human endometrial tumor cDNA library. The hMLH3 clone identified a 2,586 base pair open reading frame. It is εtructurally related to the yPMS2 protein family. It containε an open reading frame encoding a protein of 862 amino acid reεidueε. The protein exhibitε the highest degree of homology to yPMS2 with 32% identity and 66% similarity over the entire amino acid sequence. It is significant with respect to a putative identification of hMLHl, hMLH2 and hMLH3 that the GFRGEAL domain which is conserved in mutL homologs derived from E. coli is conserved in the amino acid sequences of , hMLHl, hMLH2 and hMLH3. The polynucleotides of the present invention may be in the form of RNA or in the form of DNA, which DNA includes cDNA, genomic DNA, and synthetic DNA. The DNA may be double- stranded or single-stranded, and if single stranded may be the coding strand or non-coding (anti-sense) strand. The coding sequence which encodes the mature polypeptide may be identical to the coding sequence shown in Figures l, 2 and 3 (SEQ ID No. l) or that of the deposited clone or may be a different coding sequence which coding sequence, as a result of the redundancy or degeneracy of the genetic code, encodes the same mature polypeptides aε the DNA of Figureε 1, 2 and 3 (SEQ ID No. 2, 4 and 6) or the deposited cDNA(ε) . The polynucleotides which encode for the mature polypeptides of Figures l, 2 and 3 (SEQ ID No. 2, 4 and 6) or for the mature polypeptides encoded by the deposited cDNAs may include: only the coding sequence for the mature polypeptide; the coding sequence for the mature polypeptide (and optionally additional coding sequence) and non-coding sequence, such aε introns or non-coding sequence 5' and/or 3' of the coding sequence for the mature polypeptide. Thus, the term "polynucleotide encoding a polypeptide" encompasses a polynucleotide which includes only coding sequence for the polypeptide as well as a polynucleotide which includes additional coding and/or non-coding sequence. The present invention further relates to variants of the hereinabove described polynucleotides which encode for fragments, analogs and derivativeε of the polypeptideε having the deduced amino acid εequenceε of Figureε 1, 2 and 3 (SEQ ID No. 2, 4 and 6) or the polypeptideε encoded by the cDNA of the depoεited cloneε . The variantε of the polynucleotides may be a naturally occurring allelic variant of the polynucleotideε or a non-naturally occurring variant of the polynucleotideε . Thus, the present invention includes polynucleotideε encoding the same mature polypeptides as shown in Figureε l, 2 and 3 (SEQ ID No. 2, 4 and 6) or the same mature polypeptides encoded by the cDNA of the depoεited cloneε aε well aε variantε of such polynucleotides which variantε encode for a fragment, derivative or analog of the polypeptides of Figureε 1, 2 and 3 (SEQ ID No. 2, 4 and 6) or the polypeptides encoded by the cDNA of the deposited clones. Such nucleotide variants include deletion variantε, subεtitution variantε and addition or inεertion variantε . Aε hereinabove indicated, the polynucleotides may have a coding sequence which is a naturally occurring allelic variant of the coding sequence shown in Figureε 1, 2 and 3 (SEQ ID No. 1, 3 and 5) or of the coding sequence of the depoεited clones. As known in the art, an allelic variant is an alternate form of a polynucleotide sequence which may have a subεtitution, deletion or addition of one or more nucleotideε, which does not subεtantially alter the function of the encoded polypeptide. The polynucleotideε of the preεent invention may alεo have the coding sequence fused in frame to a marker sequence which allows for purification of the polypeptides of the present invention. The marker sequence may be, for example, a hexa-histidine tag supplied by a pQE-9 vector to provide for purification of the mature polypeptides fused to the marker in the case of a bacterial host, or, for example, the marker sequence may be a hemagglutinin (HA) tag when a mammalian host, e.g. COS-7 cells, is used. The HA tag correεpondε to an epitope derived from the influenza hemagglutinin protein (Wilson, I., et al., Cell, 37:767 (1984) ) . The present invention further relates to polynucleotides which hybridize to the hereinabove-described sequences if there is at least 50% and preferably 70% identity between the sequenceε. The preεent invention particularly relateε to polynucleotideε which hybridize under εtringent conditionε to the hereinabove-deεcribed polynucleotideε. Aε herein used, the term "stringent conditions" means hybridization will occur only if there is at least 95% and preferably at least 97% identity between the sequences. The polynucleotides which hybridize to the hereinabove described polynucleotides in a preferred embodiment encode polypeptides which retain substantially the same biological function or activity as the mature polypeptides encoded by the cDNA of Figures 1, 2 and 3 (SEQ ID No. 1, 3 and 5) or the deposited cDNA(s) . The depoεit(s) referred to herein will be maintained under the terms of the Budapeεt Treaty on the International Recognition of the Depoεit of Micro-organiεmε for purposes of Patent Procedure. Theεe depoεitε are provided merely aε convenience to those of skill in the art and are not an admission that a deposit is required under 35 U.S.C. §112. The sequence of the polynucleotideε contained in the deposited materials, as well as the amino acid sequence of the polypeptideε encoded thereby, are incorporated herein by reference and are controlling in the event of any conflict with any deεcription of εequenceε herein. A license may be required to make, use or εell the depoεited materialε, and no εuch licenεe iε hereby granted. The present invention further relateε to polypeptideε which have the deduced amino acid sequence of Figureε 1, 2 and 3 (SEQ ID No. 2, 4 and 6) or which have the amino acid sequence encoded by the deposited cDNA(s) , aε well aε fragmentε, analogε and derivativeε of such polypeptideε. The terms "fragment," "derivative" and "analog" when referring to the polypeptideε of Figureε l, 2 and 3 (SEQ ID No. 2, 4 and 6) or that encoded by the deposited cDNA(s) , meanε polypeptideε which retain essentially the same biological function or activity as such polypeptideε. Thuε, an analog includes a proprotein which can be activated by cleavage of the proprotein portion to produce an active mature polypeptide. The polypeptides of the present invention may be a recombinant polypeptide, a natural polypeptide or a synthetic polypeptide, preferably a recombinant polypeptide. The fragment, derivative or analog of the polypeptideε of Figureε l, 2 and 3 (SEQ ID No. 2, 4 and 6) or that encoded by the depoεited cDNAε may be (i) one in which one or more of the amino acid reεidueε are substituted with a conserved or non-conserved amino acid residue (preferably a conserved amino acid residue) and such substituted amino acid residue may or may not be one encoded by the genetic code, or (ii) one in which one or more of the amino acid residueε includes a subεtituent group, or (iii) one in which the mature polypeptide iε fuεed with another compound, such aε a compound to increase the half-life of the polypeptide (for example, polyethylene glycol) . Such fragments, derivatives and analogε are deemed to be within the εcope of thoεe skilled in the art from the teachings herein. The polypeptideε and polynucleotideε of the present invention are preferably provided in an isolated form, and preferably are purified to homogeneity. The term "isolated" means that the material is removed from its original environment (e.g., the natural environment if it iε naturally occurring) . For example, a naturally- occurring polynucleotide or polypeptide present in a living animal is not isolated, but the same polynucleotide or polypeptide, separated from some or all of the co-existing materials in the natural system, is isolated. Such polynucleotides could be part of a vector and/or εuch polynucleotides or polypeptideε could be part of a compoεition, and εtill be isolated in that such vector or composition is not part of itε natural environment. The present invention also relateε to vectors which include polynucleotides of the present invention, host cells which are genetically engineered with vectors of the invention and the production of polypeptides of the invention by recombinant techniques. Host cells are genetically engineered (transduced or transformed or transfected) with the vectors of this invention which may be, for example, a cloning vector or an expression vector. The vector may be, for example, in the form of a plasmid, a viral particle, a phage, etc. The engineered host cells can be cultured in conventional nutrient media modified as appropriate for activating promoters, selecting transformants or amplifying the hMLHl, hMLH2 and hMLH3 genes. The culture conditions, such as temperature, pH and the like, are those previously used with the host cell selected for expresεion, and will be apparent to the ordinarily εkilled ar iεan. The polynucleotideε of the present invention may be employed for producing polypeptides by recombinant techniques. Thuε, for example, the polynucleotide may be included in any one of a variety of expression vectors for expressing a polypeptide. Such vectors include chromo omal, nonchromoεomal and εynthetic DNA sequences, e.g., derivatives of SV40; bacterial plasmids; phage DNA; baculoviruε,- yeaεt plaεmidε; vectorε derived from combinations of plasmidε and phage DNA, viral DNA such as vaccinia, adenovirus, fowl pox viruε, and pseudorabieε. However, any other vector may be used as long as it iε replicable and viable in the hoεt. The appropriate DNA sequence may be inserted into the vector by a variety of procedure . In general, the DNA sequence iε inserted into an appropriate reεtriction endonuclease εite(ε) by procedureε known in the art. Such procedureε and others are deemed to be within the scope of those skilled in the art. The DNA sequence in the expression vector iε operatively linked to an appropriate expression control sequence (ε) (promoter) to direct mRNA synthesiε . Aε repreεentative exampleε of such promoters, there may be mentioned: LTR or SV40 promoter, the E. coli. lac or trp, the phage lambda P ! promoter and other promoterε known to control expreεεion of geneε in prokaryotic or eukaryotic cellε or their viruεeε . The expression vector also containε a ribosome binding site for translation initiation and a transcription terminator. The vector may also include appropriate sequences for amplifying expression. In addition, the expression vectors preferably contain one or more selectable marker genes to provide a phenotypic trait for selection of transformed hoεt cellε such as dihydrofolate reductase or neomycin resistance for eukaryotic cell culture, or such aε tetracycline or ampicillin resistance in E. coli. The vector containing the appropriate DNA sequence aε hereinabove deεcribed, aε well as an appropriate promoter or control sequence, may be employed to transform an appropriate host to permit the host to express the proteins. As representative examples of appropriate hostε, there may be mentioned: bacterial cellε, εuch aε E. coli, Streptomvceε. Salmonella typhimurium,• fungal cellε, εuch aε yeaεt; inεect cellε εuch aε Drosophila S2 and Spodoptera Sf9; animal cellε such aε CHO, COS or Bowes melanoma; adenoviruses; plant cells, etc. The selection of an appropriate host iε deemed to be within the scope of those skilled in the art from the teachings herein. More particularly, the present invention also includes recombinant constructs comprising one or more of the sequences as broadly described above. The constructs comprise a vector, such as a plasmid or viral vector, into which a εequence of the invention has been inserted, in a forward or reverse orientation. In a preferred aspect of this embodiment, the construct further compriseε regulatory εequenceε, including, for example, a promoter, operably linked to the sequence. Large numbers of suitable vectorε and promoters are known to thoεe of εkill in the art, and are commercially available. The following vectors are provided by way of example. Bacterial: pQE70, pQE60, pQE-9 (Qiagen, Inc.), pbs, pDlO, phagescript, pεiXl74, pbluescript SK, pbsks, pNH8A, pNHi6a, pNH18A, pNH46A (Stratagene) ; ptrc99a, pKK223-3, pKK233-3, pDR540, pRlT5 (Pharmacia) . Eukaryotic: pWLNEO, pSV2CAT, pOG44, pXTl, pSG (Stratagene) pSVK3, pBPV, pMSG, pSVL (Pharmacia) . However, any other plasmid or vector may be used as long aε they are replicable and viable in the host. Promoter regions can be selected from any desired gene using CAT (chloramphenicol transferaεe) vectorε or other vectorε with selectable markers. Two appropriate vectorε are pKK232-8 and pCM7. Particular named bacterial promoterε include lad, lacZ, T3, T7, gpt, lambda P R , P, and TRP. Eukaryotic promoterε include CMV immediate early, HSV thymidine kinaεe, early and late SV40, LTRs from retrovirus, and mouse metallothionein-l. Selection of the appropriate vector and promoter iε well within the level of ordinary skill in the art. In a further embodiment, the present invention relates to host cells containing the above-deεcribed constructs. The host cell can be a higher eukaryotic cell, such as a mammalian cell, or a lower eukaryotic cell, such aε a yeaεt cell, or the host cell can be a prokaryotic cell, such as a bacterial cell. Introduction of the construct into the host cell can be effected by calcium phosphate transfection, DEAE- Dextran mediated transfection, or electroporation (Davis, L., Dibner, M. , Battey, I., Baεic Methodε in Molecular Biology, (1986) ) . The conεtructε in hoεt cellε can be uεed in a conventional manner to produce the gene product encoded by the recombinant εequence. Alternatively, the polypeptideε of the invention can be synthetically produced by conventional peptide syntheεizerε. Mature proteins can be expressed in mammalian cellε, yeaεt, bacteria, or other cellε under the control of appropriate promoterε. Cell-free tranεlation syεtemε can alεo be employed to produce such proteins using RNAs derived from the DNA constructs of the present invention. Appropriate cloning and expression vectors for use with prokaryotic and eukaryotic hoεtε are described by Sambrook, et al. , Molecular Cloning: A Laboratory Manual, Second Edition, Cold Spring Harbor, N.Y., (1989), the disclosure of which is hereby incorporated by reference. Tranεcription of the DNA encoding the polypeptideε of the present invention by higher eukaryoteε iε increased by inserting an enhancer sequence into the vector. Enhancerε are ciε-acting elements of DNA, usually about from 10 to 300 bp that act on a promoter to increase its tranεcription. Exampleε including the SV40 enhancer on the late side of the replication origin bp 100 to 270, a cytomegalovirus early promoter enhancer, the polyoma enhancer on the late side of the replication origin, and adenoviruε enhancerε. Generally, recombinant expreεεion vectorε will include originε of replication and selectable markers permitting tranεformation of the hoεt cell, e.g., the ampicillin resistance gene of E. coli and S. cerevisiae TRPl gene, and a promoter derived from a highly-expreεεed gene to direct transcription of a downstream structural sequence. Such promoters can be derived from operons encoding glycolytic enzymes εuch aε 3-phoεphoglycerate kinaεe (PGK) , α-factor, acid phoεphataεe, or heat εhock proteinε, among others. The heterologous structural sequence iε aεsembled in appropriate phase with translation initiation and termination sequences. Optionally, the heterologous sequence can encode a fusion protein including an N-terminal identification peptide imparting desired characteristicε, e.g., stabilization or simplified purification of expresεed recombinant product. Uεeful expression vectors for bacterial use are constructed by inserting a structural DNA sequence encoding a desired protein together with εuitable tranεlation initiation and termination signals in operable reading phase with a functional promoter. The vector will comprise one or more phenotypic selectable markers and an origin of replication to ensure maintenance of the vector and to, if desirable, provide amplification within the host. Suitable prokaryotic hosts for transformation include E. coli. Bacillus subtilis, Salmonella typhimurium and various species within the genera Pseudomonaε, Streptomyceε, and Staphylococcuε, although others may also be employed as a matter of choice. Aε a repreεentative but nonlimiting example, useful expression vectorε for bacterial use can comprise a selectable marker and bacterial origin of replication derived from commercially available plasmidε comprising genetic elements of the well known cloning vector pBR322 (ATCC 37017) . Such commercial vectors include, for example, pKK223-3 (Pharmacia Fine Chemicalε, Uppεala, Sweden) and GEMl (Promega Biotec, Madiεon, Wl, USA) . Theεe pBR322 "backbone" sections are combined with an appropriate promoter and the structural sequence to be expressed. Following transformation of a suitable host strain and growth of the host strain to an appropriate cell density, the selected promoter iε induced by appropriate means (e.g., temperature shift or chemical induction) and cells are cultured for an additional period. Cells are typically harvested by centrif gation, disrupted by physical or chemical means, and the resulting crude extract retained for further purification. Microbial cellε employed in expreεsion of proteins can be disrupted by any convenient method, including freeze-thaw cycling, sonication, mechanical disruption, or use of cell lysing agents, such methods are well know to those skilled in the art . Various mammalian cell culture syεtemε can alεo be employed to expreεε recombinant protein. Exampleε of mammalian expreεεion systems include the COS-7 lines of monkey kidney fibroblasts, described by Gluzman, Cell, 23:175 (1981) , and other cell lines capable of expresεing a compatible vector, for example, the C127, 3T3, CHO, HeLa and BHK cell lineε . Mammalian expreεεion vectorε will compriεe an origin of replication, a suitable promoter and enhancer, and also any necesεary ribosome binding siteε, polyadenylation εite, splice donor and acceptor εiteε, transcriptional termination sequenceε, and 5' flanking nontranεcribed εequenceε . DNA εequenceε derived from the SV40 εplice, and polyadenylation εiteε may be uεed to provide the required nontranεcribed genetic elementε. The polypeptideε can be recovered and purified from recombinant cell cultures by methodε including ammonium εulfate or ethanol precipitation, acid extraction, anion or cation exchange chromatography, phosphocelluloεe chromatography, hydrophobic interaction chromatography, affinity chromatography, hydroxylapatite chromatography and lectin chromatography. Protein refolding εtepε can be used, aε necesεary, in completing configuration of the mature protein. Finally, high performance liquid chromatography (HPLC) can be employed for final purification steps . The polypeptideε of the present invention may be a naturally purified product, or a product of chemical synthetic procedureε, or produced by recombinant techniqueε from a prokaryotic or eukaryotic host (for example, by bacterial, yeast, higher plant, insect and mammalian cells in culture) . Depending upon the host employed in a recombinant production procedure, the polypeptideε of the preεent invention may be glycosylated or may be non-glycoεylated. In accordance with a further aspect of the invention, there iε provided a process for determining susceptibility to cancer, in particular, a hereditary cancer. Thus, a mutation in a human repair protein, which is a human homolog of mutL, and in particular those described herein, indicates a susceptibility to cancer, and the nucleic acid sequenceε encoding such human homologs may be employed in an assay for ascertaining such susceptibility. Thus, for example, the assay may be employed to determine a mutation in a human DNA repair protein as herein described, such as a deletion, truncation, insertion, frame shift, etc., with such mutation being indicative of a suεceptibility to cancer. A mutation may be ascertained for example, by a DNA sequencing asεay. Tiεεue εampleε, including but not limited to blood samples are obtained from a human patient . The samples are procesεed by methodε known in the art to capture the RNA. First strand cDNA is syntheεized from the RNA εampleε by adding an oligonucleotide primer conεiεting of polythymidine reεidueε which hybridize to the polyadenosine stretch present on the mRNA'ε. Reverεe transcriptase and deoxynucleotides are added to allow εyntheεis of the first strand cDNA. Primer sequenceε are synthesized baεed on the DNA sequence of the DNA repair protein of the invention. The primer sequence is generally comprised of 15 to 30 and preferably from 18 to 25 consecutive bases of the human DNA repair gene. Table 1 sets forth an illustrative example of oligonucleotide primer sequenceε based on hMLHl . The primers are used in pairs (one "sense" strand and one "anti-sense") to amplify the cDNA from the patients by the PCR method (Saiki et al . , Nature, 324:163-166 (1986)) such that three overlapping fragments of the patient's cDNA's for such protein are generated. Table 1 also shows a list of preferred primer sequence pairs. The overlapping fragments are then subjected to dideoxynucleotide sequencing using a set of primer sequenceε εyntheεized to correεpond to the baεe pairs of the cDNA's at a point approximately every 200 base pairs throughout the gene.

Table 2 lists representative examples of oligonucleotide primer sequenceε (sense and anti-senεe) which may be used, and preferably the entire set of primer sequences are used for sequencing to determine where a mutation in the patient DNA repair protein may be. The primer sequenceε may be from 15 to 30 bases in length and are preferably between 18 and 25 bases in length. The sequence information determined from the patient iε then compared to non-mutated εequences to determine if any mutations are present.

The nucleotide sequenceε εhown in Table 2 repreεent SEQ ID No. 20 through 33, reεpectively. In another embodiment, the primer sequences from Table 2 could be used in the PCR method to amplify a mutated region. The region could be sequenced and used aε a diagnostic to predict a predisposition to such mutated genes. Alternatively, the assay to detect mutations in the genes of the present invention may be performed by genetic testing based on DNA sequence differences achieved by detection of alteration in electrophoretic mobility of DNA fragments in gelε with or without denaturing agentε. Small εequence deletionε and insertions can be visualized by high resolution gel electrophoresis. DNA fragmentε of different sequences may be distinguished on denaturing formamide gradient gels in which the mobilities of different DNA fragments are retarded in the gel at different positions according to their specific melting or partial melting temperatures (see, e.g., Myers et al . , Science, 230:1242 (1985) ) . Sequence changes at specific locations may also be revealed by nuclease protection aεsays, εuch aε RNase and Si protection or the chemical cleavage method (e.g., Cotton et al . , PNAS, USA, 85:4397-4401 (1985)). Perfectly matched sequences can be diεtinguiεhed from mismatched duplexeε by RNase A digestion or by differences in melting temperatureε. Thuε, the detection of a specific DNA sequence may be achieved by methodε such as hybridization, RNase protection, chemical cleavage, Weεtern Blot analysiε, direct DNA sequencing or the use of restriction enzymes, (e.g., Restriction Fragment Length Polymorphisms (RFLP) ) and Southern blotting of genomic DNA. In addition to more conventional gel-electrophoresiε and DNA sequencing, mutations can also be detected by in si tu analysis. The polypeptideε may also be employed to treat cancers or to prevent cancers, by expresεion of εuch polypeptideε in vivo, which is often referred to as "gene therapy." Thus, for example, cellε from a patient may be engineered with a polynucleotide (DNA or RNA) encoding a polypeptide ex vivo, with the engineered cellε then being provided to a patient to be treated with the polypeptide. Such methods are well-known in the art. For example, cells may be engineered by procedures known in the art by use of a retroviral particle containing RNA encoding a polypeptide of the present invention. Similarly, cellε may be engineered in vivo for expression of a polypeptide in vivo by, for example, procedureε known in the art . Aε known in the art, a producer cell for producing a retroviral particle containing RNA encoding the polypeptide of the preεent invention may be adminiεtered to a patient for engineering cellε in vivo and expreεεion of the polypeptide in vivo . These and other methodε for adminiεtering a polypeptide of the preεent invention by εuch method should be apparent to those skilled in the art from the teachings of the present invention. For example, the expreεεion vehicle for engineering cellε may be other than a retroviruε, for example, an adenoviruε which may be used to engineer cellε in vivo after combination with a suitable delivery vehicle. Each of the cDNA sequenceε identified herein or a portion thereof can be used in numerous ways aε polynucleotide reagents. The sequences can be used as diagnostic probes for the presence of a specific mRNA in a particular cell type. In addition, these sequenceε can be used aε diagnostic probes suitable for use in genetic linkage analysis (polymorphisms) . The sequenceε of the preεent invention are alεo valuable for chromoεome identification. The sequence is specifically targeted to and can hybridize with a particular location on an individual human chromosome. Moreover, there iε a current need for identifying particular εiteε on the chromoεome. Few chromoεome marking reagentε baεed on actual εequence data (repeat polymorphisms) are presently available for marking chromosomal location. The mapping of DNAs to chromoεomeε according to the present invention is an important firεt step in correlating those sequenceε with geneε associated with disease. Briefly, sequenceε can be mapped to chromoεomeε by preparing PCR primerε (preferably 15-25 bp) from the cDNA. Computer analyεis of the 3' untranεlated region iε uεed to rapidly εelect primerε that do not span more than one exon in the genomic DNA, thuε complicating the amplification process. These primers are then used for PCR screening of somatic cell hybrids containing individual human chromosomeε. Only those hybrids containing the human gene corresponding to the primer will yield an amplified fragment. PCR mapping of somatic cell hybrids iε a rapid procedure for assigning a particular DNA to a particular chromosome. Using the present invention with the same oligonucleotide primers, sublocalization can be achieved with panelε of fragmentε from specific chromosomes or pools of large genomic clones in an analogous manner. Other mapping εtrategieε that can εimilarly be used to map to its chromosome include in si tu hybridization, prescreening with labeled flow-sorted chromosomeε and preεelection by hybridization to conεtruct chromoεome-εpecific cDNA librarieε. Fluoreεcence in si tu hybridization (FISH) of a cDNA clone to a metaphase chromoεomal εpread can be uεed to provide a preciεe chromoεomal location in one εtep. Thiε technique can be uεed with cDNA aε εhort aε 500 or 600 baεeε; however, cloneε larger than that have a higher likelihood of binding to a unique chromoεomal location with εufficient εignal intenεity for simple detection. FISH requires use of the cloneε from which the express sequence tag or EST waε derived, and the longer the better. For example, 2,000 bp iε good, 4,000 iε better, and more than 4,000 is probably not necessary to get good results a reasonable percentage of the time. For a review of thiε technique, see Verma et al., Human Chromoεomeε: a Manual of Baεic Techniques, Pergamon Presε, New York (1988) . Once a sequence has been mapped to a precise chromosomal location, the physical position of the sequence on the chromosome can be correlated with genetic map data. Such data are found, for example, in V. McKusick, Mendelian Inheritance in Man (available on line through Johns Hopkins University Welch Medical Library) . The relationship between genes and diseases that have been mapped to the same chromosomal region are then identified through linkage analysis (coinheritance of physically adjacent genes) . Next, it is necessary to determine the differences in the cDNA or genomic sequence between affected and unaffected individualε. If a mutation iε obεerved in some or all of the affected individuals but not in any normal individuals, then the mutation is likely to be the causative agent of the disease. With current resolution of physical mapping and genetic mapping techniqueε, a cDNA precisely localized to a chromosomal region associated with the diεease could be one of between 50 and 500 potential causative geneε. (Thiε assumeε 1 megabaεe mapping reεolution and one gene per 20 kb) . hMLH2 haε been localized uεing a genomic Pl clone (1670) which contained the 5' region of the hMLH2 gene. Detailed analysiε of human metaphase chromoεome εpreadε, counterstained to reveal banding, indicated that the hMLH2 gene waε located within bands 2q32. Likewise, hMLH3 waε localized using a genomic Pl clone (2053) which contained the 3' region of the hMLH3 gene. Detailed analysiε of human metaphase chromosome spreads, counterstained to reveal banding, indicated that the hMLH3 gene was located within band 7p22, the most distal band on chromosome 7. Analyεiε with a variety of genomic cloneε showed that hMLH3 waε a member of a subfamily of related genes, all on chromosome 7. The polypeptides, their fragments or other derivatives, or analogε thereof, or cellε expressing them can be used as an immunogen to produce antibodies thereto. These antibodies can be, for example, polyclonal or monoclonal antibodies. The preεent invention alεo includeε chimeric, εingle chain, and humanized antibodieε, aε well aε Fab fragmentε, or the product of an Fab expression library. Various procedures known in the art may be used for the production of such antibodieε and fragmentε. Antibodieε generated againεt the polypeptideε correεponding to a εequence of the present invention can be obtained by direct injection of the polypeptides into an animal or by administering the polypeptideε to an animal, preferably a nonhuman. The antibody εo obtained will then bind the polypeptideε itεelf. In thiε manner, even a sequence encoding only a fragment of the polypeptides can be uεed to generate antibodieε binding the whole native polypeptideε. Such antibodieε can then be used to isolate the polypeptide from tissue expresεing that polypeptide. For preparation of monoclonal antibodieε, any technique which provideε antibodieε produced by continuouε cell line cultureε can be uεed. Exampleε include the hybridoma technique (Kohler and Milεtein, 1975, Nature, 256:495-497), the trioma technique, the human B-cell hybridoma technique (Kozbor et al. , 1983, Immunology Today 4:72), and the EBV-hybridoma technique to produce human monoclonal antibodieε (Cole, et al., 1985, in Monoclonal Antibodieε and Cancer Therapy, Alan R. Liss, Inc., pp. 77- 96) . Techniqueε described for the production of single chain antibodieε (U.S. Patent 4,946,778) can be adapted to produce single chain antibodies to immunogenic polypeptide productε of thiε invention. Alεo, tranεgenic mice may be uεed to expreεε humanized antibodieε to immunogenic polypeptide productε of thiε invention. The preεent invention will be further deεcribed with reference to the following exampleε; however, it iε to be underεtood that the preεent invention iε not limited to εuch exampleε. All partε or amountε, unleεε otherwise specified, are by weight. In order to facilitate understanding of the following exampleε certain frequently occurring methodε and/or terms will be described. "Plaεmidε" are deεignated by a lower caεe p preceded and/or followed by capital letterε and/or numbers . The starting plasmids herein are either commercially available, publicly available on an unrestricted baεiε, or can be conεtructed from available plasmids in accord with published procedures. In addition, equivalent plasmids to those described are known in the art and will be apparent to the ordinarily skilled artisan. "Digestion" of DNA refers to catalytic cleavage of the DNA with a reεtriction enzyme that actε only at certain sequences in the DNA. The various restriction enzymes used herein are commercially available and their reaction conditions, cofactorε and other requirementε were uεed aε would be known to the ordinarily εkilled artisan. For analytical purposeε, typically 1 μg of plaεmid or DNA fragment iε used with about 2 units of enzyme in about 20 μl of buffer solution. For the purpose of isolating DNA fragments for plasmid conεtruction, typically 5 to 50 μg of DNA are digested with 20 to 250 units of enzyme in a larger volume. Appropriate buffers and substrate amounts for particular restriction enzymeε are εpecified by the manufacturer. Incubation timeε of about 1 hour at 37'C are ordinarily uεed, but may vary in accordance with the εupplier'ε instructions. After digestion the reaction is electrophoresed directly on a polyacrylamide gel to isolate the desired fragment . Size separation of the cleaved fragmentε iε performed uεing 8 percent polyacrylamide gel deεcribed by Goeddel, D. et al. , Nucleic Acidε Reε. , 8:4057 (1980). "Oligonucleotideε" referε to either a εingle stranded polydeoxynucleotide or two complementary polydeoxynucleotide strands which may be chemically synthesized. Such synthetic oligonucleotides have no 5' phosphate and thuε will not ligate to another oligonucleotide without adding a phosphate with an ATP in the preεence of a kinaεe. A εynthetic oligonucleotide will ligate to a fragment that haε not been dephosphorylated. "Ligation" referε to the process of forming phosphodiester bondε between two double stranded nucleic acid fragments (Maniatiε, T. , et al. , Id., p. 146) . Unleεε otherwiεe provided, ligation may be accomplished using known bufferε and conditions with 10 unitε to T4 DNA ligase ("ligase") per 0.5 μg of approximately equimolar amounts of the DNA fragmentε to be ligated. Unless otherwiεe εtated, transformation waε performed aε deεcribed in the method of Graham, F. and Van der Eb, A., Virology, 52:456-457 (1973) . Example 1 Bacterial Expreεsion of hMLHl The full length DNA εequence encoding human DNA mismatch repair protein hMLHl, ATCC # 75649, iε initially amplified using PCR oligonucleotide primers corresponding to the 5' and 3' ends of the DNA sequence to synthesize insertion fragments. The 5' oligonucleotide primer haε the εequence 5' CGGGATCCATGTCGTTCGTGGCAGGG 3' (SEQ ID No. 34) , containε a BamHI restriction enzyme site followed by 18 nucleotides of hMLHl coding sequence following the initiation codon; the 3' sequence 5' GCTCTAGATTAACACCTCT CAAAGAC 3' (SEQ ID No. 35) contains complementary sequenceε to an Xbal εite and iε at the end of the gene. The reεtriction enzyme εiteε correspond to the restriction enzyme siteε on the bacterial expression vector pQE-9. (Qiagen, Inc., Chatsworth, CA) . The plasmid vector encodes antibiotic reεiεtance (Amp r ) , a bacterial origin of replication (ori) , an IPTG-regulatable promoter/operator (P/O) , a ribosome binding site (RBS) , a 6-hiεtidine tag (6- Hiε) and reεtriction enzyme cloning εiteε. The pQE-9 vector iε digested with BamHI and Xbal and the insertion fragmentε are then ligated into the pQE-9 vector maintaining the reading frame initiated at the bacterial RBS. The ligation mixture iε then uεed to transform the E. coli strain Ml5/rep4 (Qiagen, Inc.) which containε multiple copieε of the plaεmid pREP4, which expresseε the lacl repreεεor and alεo conferε kanamycin reεiεtance (Kan r ) . Tranεformantε are identified by their ability to grow on LB plateε and ampicillin/kanamycin reεiεtant colonieε are εelected. Plaεmid DNA iε iεolated and confirmed by reεtriction analyεiε. Cloneε containing the desired constructs are grown overnight (O/N) in liquid culture in LB media supplemented with both .Amp (100 ug/ml) and Kan (25 ug/ml) . Tho O/N culture is used to inoculate a large culture at a ratio of 1:100 to 1:250. The cellε are grown to an optical density 600 (O.D. 60ϋ ) of between 0.4 and 0.6. IPTG (isopropyl-B-D-thiogalacto pyranoside) iε then added to a final concentration of 1 mM. IPTG induceε by inactivating the lad repreεsor, clearing the P/O leading to increased gene expression. Cells are grown an extra 3 to 4 hours. Cells are then harvested by centrifugation (20 mins at 6000Xg) . The cell pellet is solubilized in the chaotropic agent 6 Molar Guanidine HC1. After clarification, solubilized hMLHl is purified from thiε εolution by chromatography on a Nickel-Chelate column under conditionε that allow for tight binding by proteinε containing the 6-Hiε tag (Hochuli, E. et al . , Genetic Engineering, Principleε & Methodε, 12:87-98 (1990) . Protein renaturation out of GnHCl can be accomplished by several protocols (Jaenicke, R. and Rudolph, R. , Protein Structure - A Practical Approach, IRL Press, New York (1990) ) . Initially, εtep dialyεiε is utilized to remove the GnHCL. Alternatively, the purified protein isolated from the Ni-chelate column can be bound to a second column over which a decreasing linear GnHCL gradient is run. The protein is allowed to renature while bound to the column and is subsequently eluted with a buffer containing 250 mM Imidazole, 150 mM NaCl, 25 mM Tris-HCl pH 7.5 and 10% Glycerol. Finally, εoluble protein is dialyzed against a storage buffer containing 5 mM Ammonium Bicarbonate. The purified protein waε analyzed by SDS-PAGE. Example 2 Spontaneouε Mutation Aεsay for Detection of the Expression of hMLHl. hMLH2 and hMLH3 and Complementation to the E . coli mutl The pQE9hMLHl, pQE9hMLH2 or pQE9hMLH3/GW3733, transformantε were subjected to the spontaneous mutation assay. The plasmid vector pQE9 was also transformed to AB1157 (k-12, argE3 hiεG4 , LeuB6 proA2 thr-1 ara-1 rpsL31 εupE44 tsx-33) and GW3733 to use as the positive and negative control respectively. Fifteen 2 ml cultures, inoculated with approximately 100 to 1000 E. coli , were grown 2xl0 8 cells per ml in LB ampicillin medium at 37°C. Ten microliters of each culture were diluted and plated on the LB ampicillin plateε to meaεure the number of viable cellε. The reεt of the cellε from each culture were then concentrated in εaline and plated on minimal plateε lacking of arginine to measure reversion of Argr + . In Table 3, the mean number of mutations per culture ( ) waε calculated from the median number {r) of mutantε per diεtribution, according to the equation (r/m) -In(m) = 1.24 (Lea et al. , J. Geneticε 49:264-285 (1949)) . Mutation rates per generation were recorded as m/N, with N representing the average number of cells per culture. TABLE 3 Spontaneous Mutation Rates Strain Mutation/generation AB1157+vector (5.6+0.1) x 10-9a GW3733+vector (1.1±0.2) x 10-6a GW3733+pllMLHl (3.7±1.3 x 10-7a GW3733+pllMLH2 (3.1±0.6) x 10-7b GW3733+phMLH3 (2.1±0.8) X 10-7b a: Average of three experiments, b: Average of four experiments. The functional complementation result showed that the human mutL can partially rescue the E.coli mutL mutator phenotype, suggesting that the human mutL is not only εucceεsfully expreεεed in a bacterial expreεεion system, but also functionε in bacteria. Example 3 Chromosomal Mapping of the hMLHl An oligonucleotide primer set waε deεigned according to the sequence at the 5 ' end of the cDNA for HMLHl. This primer set would span a 94 bp segment. This primer set waε used in a polymerase chain reaction under the following set of conditions : 30 εecondε, 95 degreeε C 1 minute, 56 degreeε C 1 minute, 70 degreeε C Thiε cycle waε repeated 32 timeε followed by one 5 minute cycle at 70 degreeε C. Human, mouεe, and hamεter DNA were uεed aε template in addition to a somatic cell hybrid panel (Bios, Inc) . The reactions were analyzed on either 8% polyacrylamide gels or 3.5 % agarose gels. A 94 base pair band waε obεerved in the human genomic DNA sample and in the εomatic cell hybrid sample corresponding to chromosome 3. In addition, uεing variouε other somatic cell hybrid genomic DNA, the hMLHl gene was localized to chromosome 3p. Example 4 Method for Determination of mutation of hMLHl gene in HNPCC kindred cDNA waε produced from RNA obtained from tiεsue sampleε from perεonε who are HNPCC kindred and the cDNA waε uεed aε a template for PCR, employing the primerε 5' GCATC TAGACGTTTCCTTGGC 3' (SEQ ID No. 36) and 5' CATCCAAGCTTCTGT TCCCG 3' (SEQ ID No. 37) , allowing amplification of codonε 1 to 394 of Figure 1; 5' GGGGTGCAGCAGCACATCG 3' (SEQ ID No. 38) and 5' GGAGGCAG.AATGTGTGAGCG 3' (SEQ ID No. 39) , allowing amplification of codonε 326 to 729 of Figure 1 (SEQ ID NO. 2) ; and 5' TCCCAAAGAAGGACTTGCT 3' (SEQ ID No. 40) and 5' AGTATAAGTCTTAAGTGCTACC 3' (SEQ ID No. 41) , allowing amplification of codonε 602 to 756 plus 128 nt of 3'- untranslated sequences of Figure 1 (SEQ ID No. 2) . The PCR conditions for all analyseε used consisted of 35 cycles at 95°C for 30 seconds, 52-58°C for 60 to 120 secondε, and 70°C for 60 to 120 εecondε, in the buffer solution deεcribed in San Sidransky, D. et al . , Science, 252:706 (1991) . PCR products were sequenced using primerε labeled at their 5' end with T4 polynucleotide kinase, employing SequiTherm Polymerase (Epicentre Technologies) . The intron-exon borders of selected exons were also determined and genomic PCR products analyzed to confirm the results. PCR products harboring suspected mutations were then cloned and sequenced to validate the results of the direct sequencing. PCR products were cloned into T-tailed vectors as deεcribed in Holton, T.A. and Graham, M.W. , Nucleic Acidε Research, 19:1156 (1991) and sequenced with T7 polymerase (United States Biochemical) . Affected individualε from seven kindreds all exhibited a heterozygous deletion of codonε 578 to 632 of the hMLHl gene. The derivation of five of these seven kindreds could be traced to a common ancestor. The genomic sequences surrounding codonε 578-632 were determined by cycle- sequencing of the Pl cloneε (a human genomic Pl library which containε the entire hMLHl gene (Genome Systems) ) using SequiTherm Polymerase, as described by the manufacturer, with the primers were labeled with T4 polynucleotide kinaεe, and by sequencing PCR products of genomic DNA. The primerε used to amplify the exon containing codonε 578-632 were 5' TTTATGGTTTCTCACCTGCC 3' (SEQ ID No. 42) and 5' GTTATCTGCCCACCTCAGC 3' (SEQ ID No. 43) . The PCR product included 105 bp of intron C εequence upεtream of the exon and 117 bp downstream. No mutations in the PCR product were observed in the kindredε, εo the deletion in the RNA waε not due to a simple splice site mutation. Codonε 578 to 632 were found to conεtitute a εingle exon which waε deleted from the gene product in the kindredε deεcribed above. This exon containε several highly conserved amino acids. In a second family (L7) , PCR was performed using the above primerε and a 4bp deletion waε obεerved beginning at the firεt nucleotide (nt) of codon 727. Thiε produced a frame shift with a new stop codon 166 nt downstream, resulting in a substitution of the carboxy-terminal 29 amino acids of hMLHl with 53 different amino acids, some encoded by nt normally in the 3' untranslated region. A different mutation waε found in a different kindred (L2516) after PCR using the above primerε, the mutation conεiεting of a 4bp inεert between codonε 755 and 756. Thiε inεertion reεulted in a frame shift and extension of the ORF to include 102 nucleotides (34 amino acids) downstream of the normal termination codon. The mutationε in both kindredε L7 and L2516 were therefore predicted to alter the C-terminuε of hMLHl. A possible mutation in the hMLHl gene was determined from alterations in size of the encoded protein, where kindreds were too few for linkage studies. The primerε used for coupled tranεcription-translation of hMLHl were 5' GGATCCTi^TACGACrrClACTATAGGGAGACCACCATGGCATCT AGACGTTTCCCTTGGC 3' (SEQ ID No. 44) and 5' CATCCAAGCTTCTGTTCCCG 3' (SEQ ID No. 45) for codons 1 to 394 of Figure l and 5' GGATCCΓAATACGACTCACTATAGGGAGACCACCATGGG GGTGCAGCAGCACATCG 3' (SEQ ID No. 46) and 5' GGAGGCAGAATGTG TGAGCG 3' (SEQ ID No. 47) for codonε 326 to 729 of Figure 1 (SEQ ID No. 2) . The resultant PCR products had signals for transcription by T7 RNA polymerase and for the initiation of translation at their 5' ends. RNA from lymphoblaεtoid cellε of patientε from 18 kindredε waε used to amplify two productε, extending from codon l to codon 394 or from codon 326 to codon 729, reεpectively. The PCR productε were then tranεcribed and tranεlated in vitro, making use of tranεcription-translation signalε incorporated into the PCR primerε. PCR productε were uεed aε templateε in coupled tranεcription-translation reactions performed as described by Powell, S.M. et al . , New England Journal of Medicine, 329:1982, (1993), using 40 micro CI of 35 S labeled methionine. Samples were diluted in sample buffer, boiled for five minutes and analyzed by electropheresis on sodium dodecyl sulfate-polyacrylamide gels containing a gradient of 10% to 20% acrylamide. The gels were dried and subjected to radiography. All sampleε exhibited a polypeptide of the expected εize, but an abnormally migrating polypeptide waε additionally found in one case. The sequence of the relevant PCR product was determined and found to include a 371 bp deletion beginning at the first nucleotide (nt) of codon 347. This alteration waε present in heterozygouε form, and resulted in a frame shift in a new stop codon 30 nt downstream of codon 346, thuε explaining the truncated polypeptide obεerved. Four colorectal tumor cell lineε manifeεting microsatellite instability were examined. One of the four (cell line H6) showed no normal peptide in thiε assay and produced only a short product migrating at 27 kd. The εequence of the corresponding cDNA was determined and found to harbor a C to A transversion at codon 252, resulting in the substitution of a termination codon for serine. In accord with the translational analyses, no band at the normal C position was identified in the cDNA or genomic DNA from thiε tumor, indicating that it waε devoid of a functional hMLHl gene. Table 4 εets forth the resultε of theεe εequencing aεεay . Deletionε were found in those people who were known to have a family history of the colorectal cancer. More particularly, 9 of 10 familieε showed an hMLHl mutation.

The 5' oligonucleotide primer has the sequence 5' CGGGATCCATGAAACAATTGCCTGCGGC 3' (SEQ ID No. 48) contains a BamHI restriction enzyme site followed by 17 nucleotideε of hMLH2 following the initiation codon. The 3' εequence 5' GCTCTAGACCAGACTCAT GCTGTTTT 3' (SEQ ID No. 49) contains complementary sequenceε to an Xbal εite and iε followed by 18 nucleotideε of hMLH2. The restriction enzyme εiteε correspond to the reεtriction enzyme sites on the bacterial expression vector pQE-9 (Qiagen, Inc. Chatsworth, CA) . pQE-9 encodes antibiotic resiεtance (Amp r ) , a bacterial origin of replication (ori) , an IPTG-regulatable promoter operator (P/O) , a riboεome binding site (RBS) , a 6-His tag and reεtriction enzyme εiteε. The amplified εequenceε and pQE- 9 are then digeεted with BamHI and Xbal. The amplified sequences are ligated into pQE-9 and are inserted in frame with the sequence encoding for the histidine tag and the RBS. The ligation mixture iε then used to transform E. coli strain Ml5/rep4 (Qiagen, Inc.) which containε multiple copies of the plasmid pREP4, which expreεεeε the lad repreεεor and alεo confers kanamycin resiεtance (Kan r ) . Tranεformantε are identified by their ability to grow on LB plateε and ampicillin/kanamycin reεiεtant colonieε are εelected. Plaεmid DNA is isolated and confirmed by restriction analysiε. Cloneε containing the deεired constructs are grown overnight (0/N) in liquid culture in LB media supplemented with both Amp (100 ug/ml) and Kan (25 ug/ml) . Tho O/N culture is used to inoculate a large culture at a ratio of 1:100 to 1:250. The cells are grown to an optical density 600 (O.D. 600 ) of between 0.4 and 0.6. IPTG (Isopropyl-B-D-thiogalacto pyranoside) is then added to a final concentration of 1 mM. IPTG induces by inactivating the lad repressor, clearing the P/0 leading to increased gene expression. Cellε are grown an extra 3 to 4 hourε . Cellε are then harvested by centrifugation (20 mins at 6000Xg) . The cell pellet iε solubilized in the chaotropic agent 6 Molar Guanidine HC1. After clarification, solubilized hMLH2 is purified from thiε εolution by chromatography on a Nickel-Chelate column under conditionε that allow for tight binding by proteinε containing the 6-Hiε tag (Hochuli, E. et al. , Genetic Engineering, Principleε &. Methodε, 12:87-98 (1990) . Protein renaturation out of GnHCl can be accomplished by several protocols (Jaenicke, R. and Rudolph, R. , Protein Structure - A Practical Approach, IRL Presε, New York (1990) ) . Initially, εtep dialyεiε iε utilized to remove the GnHCL. Alternatively, the purified protein isolated from the Ni-chelate column can be bound to a second column over which a decreasing linear GnHCL gradient iε run. The protein is allowed to renature while bound to the column and iε subsequently eluted with a buffer containing 250 mM Imidazole, 150 mM NaCl, 25 mM Tris-HCl pH 7.5 and 10% Glycerol. Finally, εoluble protein is dialyzed against a storage buffer containing 5 mM Ammonium Bicarbonate. The purified protein waε analyzed by SDS-PAGE. Example 6 Bacterial Expression and Purification of hMLH3 The DNA sequence encoding hMLH3, ATCC #75650, iε initially amplified uεing PCR oligonucleotide primerε correεponding to the 5' and 3' ends of the DNA εequence to εynthesize insertion fragments. The 5' oligonucleotide primer has the εequence 5' CGGGATCCATGGAGCGAGCTGAGAGC 3' (SEQ ID No. 50) contains a BamHI restriction enzyme site followed by 18 nucleotides of hMLH3 coding εequence εtarting from the preεumed terminal amino acid of the proceεεed protein. The 3' εequence 5' GCTCTAGAGTGAAG ACTCTGTCT 3' (SEQ ID No. 51) containε complementary εequenceε to an Xbal εite and iε followed by 18 nucleotideε of hMLH3. The reεtriction enzyme sites correspond to the restriction enzyme εiteε on the bacterial expression vector pQE-9 (Qiagen, Inc. Chatsworth, CA) . pQE-9 encodes antibiotic resistance (Amp r ) , a bacterial origin of replication (ori) , an IPTG-regulatable promoter operator (P/O) , a ribosome binding εite (RBS) , a 6-Hiε tag and reεtriction enzyme εites. The amplified εequenceε and pQE- 9 are then digeεted with BamHI and Xbal. The amplified εequenceε are ligated into pQE-9 and are inεerted in frame with the εequence encoding for the hiεtidine tag and the RBS. The ligation mixture waε then uεed to tranεform E. coli εtrain M15/rep4 (Qiagen, Inc.) which containε multiple copies of the plasmid pREP4, which expresses the lad represεor and alεo conferε kanamycin reεiεtance (Kan r ) . Transformantε are identified by their ability to grow on LB plateε and ampicillin/kanamycin reεiεtant colonieε are εelected. Plasmid DNA is isolated and confirmed by restriction analysiε. Clones containing the desired constructs are grown overnight (O/N) in liquid culture in LB media εupplemented with both Amp (100 ug/ml) and Kan (25 ug/ml) . Tho O/N culture is used to inoculate a large culture at a ratio of 1:100 to 1:250. The cells are grown to an optical density 600 (O.D. 600 ) of between 0.4 and 0.6. IPTG (Isopropyl-B-D-thiogalacto pyranoside) iε then added to a final concentration of 1 mM. IPTG induceε by inactivating the lad repreεεor, clearing the P/O leading to increased gene expresεion. Cellε are grown an extra 3 to 4 hourε. Cellε are then harveεted by centrifugation (20 minε at 6000Xg) . The cell pellet iε εolubilized in the chaotropic agent 6 Molar Guanidine HC1. After clarification, εolubilized εtanniocalcin iε purified from this solution by chromatography on a Nickel-Chelate column under conditions that allow for tight binding by proteins containing the 6-His tag (Hochuli, E. et al. , Genetic Engineering, Principles & Methods, 12:87-98 (1990). Protein renaturation out of GnHCl can be accomplished by several protocols (Jaenicke, R. and Rudolph, R. , Protein Structure - A Practical Approach, IRL Press, New York (1990)) . Initially, step dialyεiε iε utilized to remove the GnHCL. Alternatively, the purified protein iεolated from the Ni-chelate column can be bound to a second column over which a decreaεing linear GnHCL gradient iε run. The protein is allowed to renature while bound to the column and iε subsequently eluted with a buffer containing 250 mM imidazole, 150 mM NaCl, 25 mM Tris-HCl pH 7.5 and 10% Glycerol. Finally, soluble protein is dialyzed against a storage buffer containing 5 mM Ammonium Bicarbonate. The purified protein was analyzed by SDS-PAGE. Example 7 Method for determination of mutation of hMLH2 and hMLH3 in hereditary cancer Isolation of Genomic Clones A human genomic Pl library (Genomic Systemε, Inc.) waε εcreened by PCR uεing primerε εelected for the cDNA sequence of hMLH2 and hMLH3. Two cloneε were isolated for hMLH2 using primerε 5' AAGCTGCTCTGTTAAAAGCG 3' (SEQ ID No. 52) and 5' GCACCAGCATCCAAGGAG 3' (SEQ ID No. 53) and reεulting in a 133 bp product. Three cloneε were isolated for hMLH3, using primerε 5' CAACCATGAGACACATCGC 3' (SEQ ID No. 54) and 5' AGGTTAGTGAAGACTCTGTC 3' (SEQ ID No. 55) reεulting in a 121 bp product. Genomic cloneε were nick- tranεlated with digoxigenindeoxy-uridine 5' -triphoεphate (Boehringer Manheim) , and FISH waε performed as described (Johnson, Cg. et al. , Methods Cell Biol. , 35:73-99 (1991)). Hybridization with the hMLH3 probe were carried out using a vast exceεε of human cot-l DNA for specific hybridization to the expressed hMLH3 locus. Chromoεomeε were counterεtained with 4,6-diamino-2-phenylidole andpropidium iodide, producing a combination of C- and R-bandε. Aligned imageε for preciεe mapping were obtained uεing a triple- band filter set (Chroma Technology, Brattleboro, T) in combination with a cooled charge-coupled device camera (Photometries, Tucson, AZ) and variable excitation wavelength filterε (Johnson, Cv. et al. , Genet. Anal. Tech. Appl. , 8:75 (1991)). Image collection, analysiε and chromoεomal fractional length measurements were done suing the iSee Graphical Program System (Inovision Corporation, Durham, NC) . Transcription coupled Translation Mutation Analysis For purposes of IVSP analysiε the hMLH2 gene waε divided into three overlapping εegmentε. The firεt εegment included codonε 1 to 500, while the middle εegment included codonε 270 to 755, and the laεt εegment included codonε 485 to the tranεlational termination εite at codon 933. The primerε for the firεt εegment were 5' GGATCCTAATACGACTCACT ATAGGGAGACCACCATGGAACAATTGCCTGCGG 3' (SEQ ID No. 56) and 5' CCTGCTCCACTCATCTGC 3' (SEQ ID No. 57), for the middle εegment were 5' GGATCCΓΓAATACGACTCΆCTATAGGGAGACCACCATGGAAGA TATCTTAAAGTTAATCCG 3' (SEQ ID No. 58) and 5' GGCTTCTTCTACTC TATATGG 3' (SEQ ID No. 59), and for the final εegment were 5' GGATCCT.AATACGACπ'C^CTATAGGGAGACCACCΑTGGCΑGGTCrrTGAAAACTC TTCG 3' (SEQ ID No. 60) and 5' AAAACAAGTCAGTGAATCCTC 3' (SEQ ID No. 61) . The primerε used for mapping the stop mutation in patient CW all used the same 5' primer as the firεt segment. The 3' nested primerε were: 5' AAGCACΑTCTGTTTCTGCTG 3' (SEQ ID No. 62) COdonε 1 to 369; 5' ACGAGTAGATTCCTTTAGGC 3' (SEQ ID No. 63) COdonε 1 to 290; and 5' CAGAACTGACATGAGAGCC 3' (SEQ ID No. 64) codonε 1 to 214. For analyεiε of hMLH3, the hMLH3 cDNA waε amplified aε a full-length product or aε two overlapping εegmentε. The primerε for full-length hMLH3 were 5' GGATCCTAATACGACrrC^CrrATAGGGAGACCACCATGGAGCGAGCTGAGAGC 3 ' (SEQ ID No. 65) and 5' AGGTTAGTGAAGACTCTGTC 3' (SEQ ID No. 66) (codonε l to 863) . For segment 1, the sense primer waε the same as above and the antisense primer was 5' CTGAGGTCT CAGCAGGC 3' (SEQ ID No. 67) (codons 1 to 472) . Segment 2 primerε were 5' GGATCCTAATACGACTCACTATAGGGAGACCACCATGGTGTC CATTTCCAGACTGCG 3' (SEQ ID No. 68) and 5' AGGTTAGTGAAGACTCT GTC 3' (SEQ ID No. 69) (codonε 415 to 863) . Amplificationε were done as described below. The PCR products contained recognition εignalε for tranεcription by T7 RNA polymeraεe and for the initiation of tranεlation at thei 5' endε. PCR productε were uεed aε templateε in coupled tranεcription-tranεlation reactionε containing 40 uCi of 36 S-methionine (NEN, Dupont) . Sampleε were diluted in SDS εample buffer, and analyzed by electrophoreεiε on SDS-polyacrylamide gelε containing a gradient of 10 to 20% acrylamide. The gelε were fixed, treated with EnHance (Dupont) , dried and εubjected to autoradiography. RT-PCR and Direct Sequencing of PCR Products cDNAs were generated from RNA of lymphoblastoid or tumor cellε with Superscript II (Life Technologies) . The cDNAs were then uεed aε templates for PCR. The conditions for all amplificationε were 35 cycleε at 95°C for 30ε, 52°C to 62°C for 60 to 120ε, and 70°C for 60 to 120ε, in buffer. The PCR productε were directly sequenced and cloned into the T-tailed cloning vector PCR2000 (Invitrogen) and sequenced with T7 polymerase (United States Biochemical) . For the direct sequencing of PCR productε, PCR reactionε were first phenolchloroform extracted and ethanol precipitated. Templates were directly sequenced using Sequitherm polymerase (Epicentre Technologies) and gamma- 32 P labelled primerε aε described by the manufacturer. Intron/Exon Boundaries and Genomic Analysis of Mutations Intron/exon borderε were determined by cycle- sequencing Pl cloneε uεing gamma- 32 P end labelled primerε and SequiTherm polymeraεe aε deεcribed by the manufacturer. The primerε used to amplify the hMLH2 exon containing codons 195 to 233 were 5' TTATTTGGCAGAAAAGCAGAG (SEQ ID No. 70) 3' and 5' TTAAAAGACTAACCTCTTGCC 3' (SEQ ID NO. 71), which produced a 215 bp product. The product waε cycle sequenced using the primer 5' CTGCTGTTATGAACAATATGG 3' (SEQ ID No. 72) . The primerε used to analyze the genomic deletion of hMLH3 in patient GC were: for the 5' region amplification 5' CAGAAGCAGTTGCAAAGCC 3' (SEQ ID No. 73) and 5' AAACCGTACTCTTCACACAC 3' (SEQ ID No. 74) which produces a 74 bp product containing codons 233 to 257, primerε 5' GAGGAAAAGCTTTTGTTGGC 3' (SEQ ID No. 75) and 5' CAGTGGCTGCTGACTGAC 3' (SEQ ID No. 76) which produce a 93 bp product containing the codons 347 to 377, and primers 5' TCCAG.AACCAAGAAGGAGC 3' (SEQ ID No. 77) and 5' TGAGGTCTCAGCAGGC 3' (SEQ ID No. 78) which produce a 99 bp product containing the codons 439 to 472 of hMLH3.
