Function

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.

Supplementary info

Activity summary

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.

Associated diseases and disorders

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.

    ICC/IF image of ab93663 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab93663, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h.Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
