"During the course of our studies, we observed that mutating theUSP4 catalytic cysteine to alanine (C311A) to render USP4 enzymatically inactive (" catalytic-dead " [CD]), almost totally abrogated its interactions with CtIP and MRN (XREF_FIG A; note that binding of USP4 to CtIP and RAD50 was not abrogated by the DNA intercalating agent ethidium bromide (EtBr), suggesting that interaction was not mediated by DNA bridging."

"USP4, for example, interacts directly with end resection factors CtIP and MRN [172], USP21 deubiquitinates and stabilizes BRCA2 to promote RAD51 binding and successful HR [173], and USP10 deubiquitinates and stabilizes p53 to promote its nuclear localization and apoptosis in response to DSBs [174]."
