Anti-Rif1 antibody,Abcam,AB13422

Target data 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 (PubMed : 23306437, PubMed : 23306439, PubMed : 23333305). In response to DNA damage, interacts with ATM-phosphorylated TP53BP1 (PubMed : 23306437, PubMed : 23306439, PubMed : 23333305). Interaction with TP53BP1 leads to dissociate the interaction between NUDT16L1/TIRR and TP53BP1, thereby unmasking the tandem Tudor-like domain of TP53BP1 and allowing recruitment to DNA DSBs (By similarity). Once recruited to DSBs, RIF1 and TP53BP1 act by promoting NHEJ-mediated repair of DSBs (PubMed : 23306437, PubMed : 23333305). In the same time, RIF1 and TP53BP1 specifically counteract the function of BRCA1 by blocking DSBs resection via homologous recombination (HR) during G1 phase (PubMed : 23306437, PubMed : 23333305). Also required for immunoglobulin class-switch recombination (CSR) during antibody genesis, a process that involves the generation of DNA DSBs (PubMed : 23306439, PubMed : 23333305, PubMed : 23333306). Promotes NHEJ of dysfunctional telomeres (PubMed : 23333305). See full target information Telomere-associated protein RIF1
