Background

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).

FAQs for 53BP1 Antibody (NBP2-80550). (Showing 1 - 2 of 2 FAQ).

  1. We're looking for anti53BP1 antibody covalently labeled with a fluorofor preferabley Cy3. Do you make it?
    • We sell 53BP1 antibodies available conjugated to DyLight 488, 550 (very similar in spectrum to Cy3) and 650. You may also purchase the unlabeled antibodies and conjugate them to the fluorophores of your choice. The catalog numbers that you may be interested in are: NB100-904R, NB100-304R, NB100-305R.
  2. Hello I want to ask you for an advice in case of antibodies. In our research we focus on DNA repair foci and use your Novus antibodies for phosphorylated histone H2AX (monoclonal mouse) and protein 53BP1(polyclonal rabbit). Now we want to use antobody for phosphorylated 53BP1 protein to increase specifity and I want to ask you which from your NOVUS antibodies will be the best for us.
    • We currently stock just one antibody to phosphorylated 53BP1, which you can see at the following link: NB100-1803. This is guaranteed for detection of 53BP1 (pSer25) in human and mouse samples by WB, FLOW, ICC/IF,IHC-P, IP and PLA. As this antibody is a rabbit polyclonal, you would be unable to stain for both 53BP1 and its phosphorylated isoform in the same sample, unless you used an antibody from a different host for detection of total 53BP1 or used directly conjugated primaries. Our mouse monoclonal to 53BP1, with catalogue number NBP2-25028, is validated for detection of the human protein by WB, FLOW and IHC. Unfortunately we do not currently stock any other antibodies to phosphorylated 53BP1.
