APF01624MutS domain I (MutS_I)MutS domain IThis domain is found in proteins of the MutS family (DNA mismatch repair proteins) and is found associated with Pfam:PF00488, Pfam:PF05188, 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]. The aligned region corresponds with globular domain I, which is involved in DNA binding, in Thermus aquaticus MutS as characterised in [4].

APF00855PWWP domain (PWWP)PWWP domainThe PWWP domain is named after a conserved Pro-Trp-Trp-Pro motif [1]. The domain binds to Histone-4 methylated at lysine-20, H4K20me, suggesting that it is methyl-lysine recognition motif. Removal of two conserved aromatic residues in a hydrophobic c ...The PWWP domain is named after a conserved Pro-Trp-Trp-Pro motif [1]. The domain binds to Histone-4 methylated at lysine-20, H4K20me, suggesting that it is methyl-lysine recognition motif. Removal of two conserved aromatic residues in a hydrophobic cavity created by this domain within the full-length protein, Pdp1, abolishes the interaction o f the protein with H4K20me3. In fission yeast, Set9 is the sole enzyme that catalyses all three states of H4K20me, and Set9-mediated H4K20me is required for efficient recruitment of checkpoint protein Crb2 to sites of DNA damage. The methylation of H4K20 is involved in a diverse array of cellular processes, such as organising higher-order chromatin, maintaining genome stability, and regulating cell-cycle progression [2].

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).

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]. The aligned region corresponds with domain III, which is central to the structure of Thermus aquaticus MutS as characterised in [4].

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]. The aligned region corresponds with domain V of Thermus aquaticus MutS as characterised in [4], which contains a Walker A motif, and is structurally similar to the ATPase domain of ABC transporters.
