NCBI Protein Information
homolog of DNA mismatch repair protein MSH3
NCBI Summary
encodes a DNA mismatch repair homolog of human MutS gene, MSH6. There are four MutS genes in Arabidopsis, MSH2, MSH3, MSH6, and MSH7, which all act as heterodimers and bind to 51-mer duplexes. MSH2*MSH3 heterodimers bound 'insertion-deletion' DNA with three nucleotides (+AAG) or one nucleotide (+T) looped out much better than they bound DNA with a base/base mispair (T/G).

UniProt Comments
Component of the post-replicative DNA mismatch repair system (MMR). Forms the heterodimer MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. MutS beta recognizes single base mismatches and trinucleotide insertion-deletion loops (IDL) in the DNA.
