MSH3, also known as DNA mismatch repair protein Msh3, Protein repair-1, REP-1, or Protein repair-3, REP-3, and encoded by the gene MSH3/REP-3, is an important component of the post-replicative DNA mismatch repair system. MSH3 heterodimerizes with MSH2 to form a complex named MutS beta which binds...
