Western Blot: 53BP1 Antibody (1285A)Azide and BSA Free [MAB18771]

Western Blot: 53BP1 Antibody (1285A) [MAB18771] - Analysis of HEK293 and ZR-75 cell lysates with 1 ug/ml of h53BP1 Monoclonal Antibody followed by HRP-conjugated Anti-Rabbit IgG Antibody. The molecular weight was observed for h53BP1 at approximately 350 kDa (as indicated), and the theoretical molecular weight of the whole endogenous protein is 214 kDa. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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).
