MSH2
Universal Cellular Machinery · DNA Damage Repair & Genomic Integrity
What helps cells locate mismatched letters in newly copied DNA?
MSH2 makes a protein that partners with other mismatch-repair components to recognize copying errors. Finding the error is an early step before the repair machinery can correct it.
