XRCC2 Is a Nuclear RAD51-like Protein Required for Damage-dependent RAD51 Focus Formation without the Need for ATP Binding

Abstract excerpt

The human XRCC2 gene was recently identified by its ability to complement a hamster cell line, irs1, which is sensitive to DNA-damaging agents and shows genetic instability. The XRCC2 protein is highly conserved in mammalian species and has structural features, including a putative ATP-binding domain (P-loop), consistent with membership of the RecA/RAD51 family of recombination-repair proteins. We show that a...
