Background: 53BP1

Tumor protein p53 binding protein 1 (P53-binding protein 1 or 53BP1) plays a critical role in tumor suppression and is a putative substrate of ATM kinase with a theoretical molecular weight of 214 kDa. Upon DNA damage, it is phosphorylated and relocalizes to the presumptive sites of damage, specifically, double-strand breaks. 53BP1 plays a key role in response to DNA damage, acts as a signaling checkpoint during mitosis, and enhances TP53-mediated transcriptional activation. Originally identified as p53's transcriptional enhancing partner, 53BP1 is known as a key substrate for ataxia telangiectasia mutated (ATM) signaling, whose function to generate gamma H2AX may be partially compensated by the activity of DNA-dependent kinase (DNA-PK). 53BP1 relocalizes to discrete foci overlapping with gamma phosphorylated histone H2AX; demarcating DNA double strand breaks (DSBs) sites following exposure to radiation (1). 53BP1 functions downstream of gamma H2AX-dependent proteins that collectively establish ionizing radiation induced foci at DSBs. 53BP1 is downstream of Mre11/Rad50/NBS1 (MRN complex), MDC1, RNF8, RNF168 and HERC2 which recruit 53BP1 to the DSB site, suggesting a role in DNA repair through genomic stability maintenance (2).
