Mismatch Repair Endonuclease PMS2

A MutL protein and component of the DNA MISMATCH REPAIR system. Its ENDONUCLEASE activity introduces SINGLE-STRAND DNA BREAKS which create entry points for EXO1 exonuclease to remove the strand containing the mismatch. It may also function in DNA DAMAGE signaling.
