Function

Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MSH2 to form MutS alpha, which binds to DNA mismatches thereby initiating DNA repair. When bound, MutS alpha bends the DNA helix and shields approximately 20 base pairs, and recognizes single base mismatches and dinucleotide insertion-deletion loops (IDL) in the DNA. After mismatch binding, forms a ternary complex with the MutL alpha heterodimer, which is thought to be responsible for directing the downstream MMR events, including strand discrimination, excision, and resynthesis. ATP binding and hydrolysis play a pivotal role in mismatch repair functions. The ATPase activity associated with MutS alpha regulates binding similar to a molecular switch: mismatched DNA provokes ADP-->ATP exchange, resulting in a discernible conformational transition that converts MutS alpha into a sliding clamp capable of hydrolysis-independent diffusion along the DNA backbone. This transition is crucial for mismatch repair. MutS alpha may also play a role in DNA homologous recombination repair. Recruited on chromatin in G1 and early S phase via its PWWP domain that specifically binds trimethylated 'Lys-36' of histone H3 (H3K36me3): early recruitment to chromatin to be replicated allowing a quick identification of mismatch repair to initiate the DNA mismatch repair reaction.

Activity summary

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.

Associated diseases and disorders

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.

The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab198334 at 1/100 dilution (shown in red) and Alexa Fluor® 488 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    This product also gave a positive signal under the same testing conditions in HeLa cells fixed with 100% methanol (5min).
