WebIt has been shown that cancer predisposition is attributable to defects in any one of four genes, all of which encode homologs of the microbial mismatch repair proteins mutS and mutL. The human Mut-S-Homologon-2 gene (hMSH-2) specifies a mutS homolog, whereas hMLH-1, hPMS-1 and hPMS-2 encode homologs of mutL. WebDNA mismatch repair (MMR) corrects mismatched base pairs mainly caused by DNA replication errors. The fundamental mechanisms and proteins involved in the early reactions of MMR are highly conserved in almost all organisms ranging from bacteria to human. The significance of this repair system is also indicated by the fact that defects in …
