• Target description: TP53-binding protein 1 (UniProt: Q12888; also known as 53BP1, p53-binding protein 1, p53BP1) is encoded by the TP53BP1 gene (Gene ID: 7158) in human. 53BP1 is a homooligomeric double-strand break (DSB) repair protein that is involved in response to DNA damage and promotes non-homologous end joining (NHEJ)-mediated repair. It counteracts the function of the homologous recombination (HR) repair protein BRCA1. In response to DSB it undergoes phosphorylation by ATM, which promotes interaction with RIF1 and dissociation from NUDT16L1/TIRR, leading to recruitment to DSBs sites where it binds histone H2A monoubiquinated at lysine 15 (H2AK15Ub) and histone H4 dimethylated at lysine 20 (H4K20me2). Its Tudor-like region (aa 1484-1603) mediates its binding to H4K20m3e2. In the absence of DNA damage, it is phosphorylated at basal level, but following DSB and phosphorylation by ATM it interacts with PAX-interacting protein 1 (PAXIP1) and non-homologous end joining of dysfunctional telomeres. Three isoforms of 53BP1 have been described that are produced by alternative splicing. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
