Eukaryotic DNA mismatch repair (MMR) involves both Exonuclease 1 (Exo1)-dependent and -independent pathways. We found that the unstructured C-terminal domain of Saccharomyces cerevisiae Exo1 contains two Msh2-Interacting-Peptide (SHIP) boxes downstream from the Mlh1-Interacting-Peptide (MIP) box. These three sites were redundant in Exo1-dependent MMR in vivo and could be replaced by an N-terminal-Exo1-Msh6 fusion protein. The SHIP-Msh2 interactions were eliminated by the msh2-M470I mutation and wild-type but not mutant SHIP peptides eliminated Exo1-dependent MMR in vitro. We identified two S. cerevisiae SHIP box-containing proteins and three candidate human SHIP box-containing proteins. One of these, Fun30, played a small role in Exo1-dependent MMR in vivo. The Rsc complex acted in both Exo1-dependent and Exo1-independent MMR in vivo. Our results identified two modes of Exo1 recruitment and a peptide module that mediates interactions between Msh2 and other proteins, and support a model in which Exo1 functions in MMR tethered to the Msh2-Msh6 complex.
