USP25 deubiquitinates BRCA2. 6 / 6
| 6

reach
"To determine whether USP21 can promote the deubiquitination of endogenous BRCA2 and/or the BRCA2 associated RAD51 and PALB2 proteins XREF_BIBR, XREF_BIBR, we measured the extent of (poly-) ubiquitin modifications on either protein in the presence or absence of USP21 overexpression."

reach
"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]."

reach
"USP21 interacts with and deubiquitinates BRCA2."

reach
"By deubiquitinating and stabilizing BRCA2, USP21 promotes efficient RAD51 accumulation at DSBs."

reach
"To determine whether USP21 is sufficient to deubiquitinate BRCA2 fragments, we performed in vitro deubiquitination assays using HA ubiquitinated, immuno purified BRCA2 fragments as well as full-length Flag-BRCA2."

reach
"We now show that USP21 interacts with and deubiquitinates BRCA2 and that USP21 loss results in decreased BRCA2 expression in tumor cell lines."
