What is the function of this protein?
Double-strand break (DSB) repair protein involved in response to DNA damage, telomere dynamics and class-switch recombination (CSR) during antibody genesis (PubMed:15159415, PubMed:15077110, PubMed:20453858, PubMed:23333305, PubMed:26308889, PubMed:20362325).  Plays a key role in the repair of double-strand DNA breaks (DSBs) in response to DNA damage by promoting non-homologous end joining (NHEJ)-mediated repair of DSBs and specifically counteracting the function of the homologous recombination (HR) repair protein BRCA1 (PubMed:23333305, PubMed:20362325, PubMed:30297459).  In response to DSBs, phosphorylation by ATM promotes interaction with RIF1 and dissociation from NUDT16L1/TIRR, leading to recruitment to DSBs sites.  Recruited to DSBs sites by recognizing and binding histone H2A monoubiquitinated at 'Lys-15' (H2AK15Ub) and histone H4 dimethylated at 'Lys-20' (H4K20me2), two histone marks that are present at DSBs sites.  Required for immunoglobulin class-switch recombination (CSR) during antibody genesis, a process that involves the generation of DNA DSBs (PubMed:15159415, PubMed:15077110).  Participates in the repair and the orientation of the broken DNA ends during CSR (PubMed:26308889).  In contrast, it is not required for classic NHEJ and V(D)J recombination (PubMed:15159415).  Promotes NHEJ of dysfunctional telomeres (By similarity).
What are the official names of this protein?
TP53-binding protein 1, 53BP1, p53-binding protein 1, p53BP1.
What are the subcellular locations of this protein?
Nucleus. Chromosome. Chromosome, centromere, kinetochore. Note=Localizes to the nucleus in absence of DNA damage (PubMed:11801725). Following DNA damage, recruited to sites of DNA damage, such as double stand breaks (DSBs) (PubMed:11673449, PubMed:23209566, PubMed:23333305, PubMed:23306439). Recognizes and binds histone H2A monoubiquitinated at 'Lys-15' (H2AK15Ub) and histone H4 dimethylated at 'Lys-20' (H4K20me2), two histone marks that are present at DSBs sites (PubMed:23209566). Associated with kinetochores during mitosis (PubMed:11801725).
