This domain is found in proteins of the MutS family (DNA mismatch repair proteins) and is found associated with Pfam:PF00488, Pfam:PF01624, Pfam:PF05192 and Pfam:PF05190. The MutS family of proteins is named after the Salmonella typhimurium MutS protein involved in mismatch repair; other members of the family included the eukaryotic MSH 1,2,3, 4,5 and 6 proteins. These have various roles in DNA repair and recombination. Human MSH has been implicated in non-polyposis colorectal carcinoma (HNPCC) and is a mismatch binding protein [2]. This domain corresponds to domain II in Thermus aquaticus MutS as characterised in [4], and has similarity resembles RNAse-H-like domains (see Pfam:PF00075).	Domain
