The DNA mismatch repair (MMR) system maintains genome integrity by correcting replication errors. MMR also stimulates checkpoint and cell death responses to DNA damage suggested by the resistance of MMR-defective tumor cells to several chemotherapeutic agents. MMR-dependent cytotoxic response may result from futile repair; however, MMR-mediated apoptosis has been genetically separated from its repair function. In a recent issue of Molecular Cell, Yoshioka and coworkers show that MMR complexes (MutSα and MutLα) are required for the recruitment of ATR-ATRIP to sites of alkylation damage, demonstrating that MMR complexes can function as sensors in DNA damage signal transduction.
