The human MSH - 2 gene product is a member of a highly conserved family of proteins which are involved in post - replication mismatch repair . hMSH - 2 is homologous to Escherichia coli ( E . coli ) MutS and Sacchromyces cerevisiae MSH - 1 and MSH - 2 proteins , which recognise heteroduplex DNA at the sites of all single base mismatches and deletions or insertions up to 4 base pairs . hMSH - 2 is one of the hereditary non - polyposis colorectal cancer ( HNPCC ) tumor suppressor genes , and maps to human chromosome 2p16 .
