Anti-MSH6 antibody

This supplementary information is collated from multiple sources and compiled automatically. MSH6 also known as MutS Homolog 6 is a DNA repair protein that plays a role in the mismatch repair (MMR) system. It has a molecular mass of approximately 136 kDa. MSH6 forms a heterodimer with MSH2 called MutSα and this complex identifies base-pair mismatches and insertion-deletion loops during DNA replication. It is expressed in various tissues throughout the body and high levels are often found in proliferative tissues where active DNA replication occurs. Biological function summary MSH6 functions as part of the MMR complex which is essential for maintaining genomic stability. The MutSα complex where MSH6 pairs with MSH2 operates along with other proteins in the MMR pathway to correct DNA replication errors. MSH6 is also known to interact with PCNA a DNA polymerase processivity factor which facilitates its role in the repair process. Pathways MSH6 participates prominently in the DNA mismatch repair pathway. This pathway is critical for correcting DNA errors and preventing mutations during replication. In association with MLH1-PMS2 (MutLα complex) MSH6 ensures that DNA integrity is preserved. Additionally MSH6 is involved in the base excision repair (BER) pathway where it collaborates with other repair proteins to fix small base lesions. MSH6 has a significant connection with Lynch syndrome also known as hereditary nonpolyposis colorectal cancer (HNPCC). This condition is characterized by germline mutations in MMR genes including MSH6 leading to increased cancer risk particularly in the colon. Moreover alterations in MSH6 can contribute to microsatellite instability a feature seen in certain types of endometrial cancer. Mutations in MSH2 often accompany MSH6 mutations in these disorders further impacting the MMR pathway's efficiency.
