UniProt ID P43246
Protein name DNA mismatch repair protein Msh2 (hMSH2) (MutS protein homolog 2)
Protein function Component of the post-replicative DNA mismatch repair system (MMR). Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. When boun
