We examined the cellular responses of MSH2-deficient mouse cells to X-rays to clarify the role of MSH2 in recombinational repair. Eukaryotes possess three homologs of bacterial mutS that encode proteins known to function in MMR: MSH2, MSH3, and MSH6. The protein products of these genes form two heterodimeric complexes, MSH2-MSH3 (also called MutSβ) and MSH2-MSH6 (also called MutSα), which have slightly different, but partially redundant roles in recognizing mispairs (Fig. 2). Function i Component of the post-replicative DNA mismatch repair system (MMR). Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. The MSH2 gene encodes a protein that plays a role in DNA repair.

When the MSH2 protein is absent or abnormal, the number of mistakes that are left unrepaired during cell division increases substantially. If the cells continue to divide, errors accumulate in DNA and the cells become unable to function properly and may form a tumor in the colon, endometrium or another part of the body.

Germline mutations in these genes is a cause of Lynch syndrome, also known as hereditary non-polyposis colon cancer (HNPCC) Component of the post-replicative DNA mismatch repair system (MMR). Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair.

2). Function i Component of the post-replicative DNA mismatch repair system (MMR). Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. The MSH2 gene encodes a protein that plays a role in DNA repair. It helps fix mistakes that occur during DNA replication. Mutations of this gene can lead to higher risk for cancer (R).

The MSH2 protein combines with one of two other proteins — Loss of function of mismatch repair genes (MLH1, MSH2, MSH6, PMS1, PMS2) leads to microsatellite instability and colorectal cancer (CRC). Germline mutations in these genes is a cause of Lynch syndrome, also known as hereditary non-polyposis colon cancer (HNPCC) Component of the post-replicative DNA mismatch repair system (MMR).

UniProtKB/Swiss-Prot Function: Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MLH1 to form MutL alpha.
