RIF1 | Telomere-associated protein RIF1; Key regulator of TP53BP1 that plays a key role in the repair of double-strand DNA breaks (DSBs) in response to DNA damage: acts by promoting non-homologous end joining (NHEJ)-mediated repair of DSBs. In response to DNA damage, interacts with ATM- phosphorylated TP53BP1, allowing recruitment to DNA DSBs (By similarity). Once recruited to DSBs, RIF1 and TP53BP1 act by promoting NHEJ-mediated repair of DSBs. In the same time, RIF1 and TP53BP1 specifically counteract DSBs resection via homologous recombination (HR) during G1 phase (By similarity). (2168 aa) | ||||
