In this study, we show that the BRCT mutant of BRCA1, R1699W, which is associated with increased risk of breast cancer, is unable to interact with RAP80," scientists in the United States report. "Previously, we showed that ataxia-telangiectasia mutated protein kinase (ATM) can phosphorylate RAP80 in vitro at Ser(205), but whether this site is a target of ATM in whole cells was not established. To address this question, we generated an...
