The complex of MRN (MRE11A:RAD50:NBN) and RBBP8 (CtIP) performs a limited resection of DNA double strand breaks (DSBs) in the process of microhomology-mediated end joining (MMEJ) (Yun et al. 2009). ATM activation inhibits MMEJ-related resection of DNA DSBs by MRN, possibly through MRN phosphorylation (Rahal et al. 2010).
