Background

NBS1 (Nijmegen breakage syndrome protein 1, Nibrin) is the eukaryotic component of MRN complex (Mre11-Rad50-Nbs1) involved in homologous recombination repair for DNA double-strand breaks (DSBs) and DNA damage-induced checkpoint activation. NBS1, a nuclear protein with a theoretical molecular weight of 65-85 kDa, is composed of 2 functional regions: the forkhead associated (FHA) N-terminal domain (24-83 amino acids) and the breast cancer C-terminus (BRCT) domain (105-181 amino acids). Mutations in the NBN gene are associated with Nijmegen breakage syndrome, characterized by microcephaly, growth retardation, immunodeficiency, and an increased susceptibility to prostate cancer, lung cancer, liver cancer and intrahepatic cholangiocarcinoma (IHC) (1).

In DNA double strand break repair, the FHA/BRCT domains bind DNA damage sensor proteins including gamma H2AX (phospho Ser139), phosphorylated MDC1 and CtIP (CtBP-interacting protein). NBS1 then recruits the other members of the MRN complex, Mre11 and Rad50, to the proximity of DNA DSBs. The MRN complex has also been shown to interact with ATM or ATR kinases in the presence of DSBs or replication fork stalling, respectively. Phosphorylation of NBS1 at Ser 278 and Ser343 in response to ionizing radiation (IR) is dependent on ATM and is important for activation of the S phase checkpoint. The activation of ATM in response to DNA damage is also facilitated by MRN and may lead to induction of apoptosis (2, 3).

FAQs for Nbs1 Antibody (NB100-143). (Showing 1 - 8 of 8 FAQs).

  1. If this product is used in an application or species as a part of a customer review, will that validate this product in the application/species?
    • Yes, if this product is used in an untested application or species and it is shown to work through images from customer reviews or through publications, this validates the application/species for this product.
  2. What research areas can this product be used in?
    • All Nbs1 products can be used in Breast Cancer, Cancer, Checkpoint signaling, Chromatin Research, DNA Double Strand Break Repair, DNA Repair, Homologous Recombination, Non-homologous end-joining, Tumor Suppressors, and Cell Cycle and Replication.
  3. What is NBS1?
    • NBS1 is Nijmegen breakage syndrome protein 1, or Nibrin. Please refer to the background listed in the datasheet for a full summary of this common name.
  4. What is the theoretical molecular weight of Nbs1 antibodies?
    • In general, there is only one isoform described for this target. The TMW of the human form of the target protein is 85kDa. The mouse form is 84kDa. However, the observed molecular weight may vary.
  5. I would like to use the NBN Antibody for IP. What kind of Ig subclass for NBN is present in the whole antisera (IgG1 etc.) ?
    • As this antibody was produced in rabbit, it is IgG as this is all they produce.
  6. I would like to know if the antibody NB100-143 is suitable to recognize the N-terminal end of the NBS1 protein?
    • Unfortunately, the immunogen sequence for NB100-143 is within the second half of the amino acid sequence of (human) NBS1, and therefore I do not think it would be able to recognize the N-terminal end of the protein.
  7. I have a question about your product, NBS1 antibody (NB100-143). Data sheet describes that the immunogen is partial length human NBS1 protein [Swiss-Prot# O60934]. Would you specifically tell me which portion of NBS1 (with the amino acids number) is used as its immunogen?
    • Our NBS1 product NB100-143 was made to a sequence that falls between amino acids 395-754 of human Nibrin (UniProt O60934). The exact sequence is proprietary, but I hope the immunogen range will be sufficient for your needs.
  8. I am doing ICC with Nbs1 antibody [NB100-143]. Do you have any recommendations on sample preparation?
    • Nbs1 protein is located in nuclei, so after fixation in 4% PFA, permeabilize the cells wurg 0.25% tritonX-100 in PBS, 10min room temperature.
