ab225126 staining MSH3 in HT-29 cells. 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 ab225126 at 1/1000 dilution (shown in green) and ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 594), at 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The mutS homolog 3 (MSH3) protein plays an important role in DNA mismatch repair. It is part of the family of MutS proteins and is sometimes referred to by its gene name MSH3. MSH3 forms a heterodimer with MSH2 to create MutSβ. This complex targets insertion and deletion loops. The mass of MSH3 is approximately 127 kDa. Expression of MSH3 occurs in various tissues with high levels in the colon small intestine and testis.
Biological function summary

MSH3 contributes to genome stability by correcting DNA replication errors. As part of the MutSβ complex it identifies and initiates repair of insertion and deletion loops which helps maintain genomic integrity. In eukaryotes MSH3 along with its partner MSH2 cooperates with other proteins such as MLH1 and PMS2 to ensure proper mismatch repair. These interactions help to prevent mutations from becoming permanent.

Pathways

MSH3 participates in the DNA mismatch repair pathway important for maintaining genomic fidelity. It works closely with MSH2 to form MutSβ enhancing the repair of small loops. Another important association includes the MLH1-PMS2 complex within the mismatch repair pathways. This collaboration ensures errors in DNA during replication do not lead to genomic instability.

Mutations or malfunctioning of MSH3 have been associated with colorectal cancer and Lynch syndrome. Alterations in MSH3 can impair DNA repair processes contributing to cancer development. The MSH2 protein which pairs with MSH3 also plays a critical role in these disorders. Understanding MSH3 function helps illuminate its involvement in genetic stability and its impact on health.

Target data

Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MSH2 to form MutS beta which binds to DNA mismatches thereby initiating DNA repair. When bound, the MutS beta heterodimer bends the DNA helix and shields approximately 20 base pairs. MutS beta recognizes large insertion-deletion loops (IDL) up to 13 nucleotides long. 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.
