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 ~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.
