Nbs1 Antibody (1D7) Summary

Immunogen
The complete coding region of the human p95/Nbs1 expressed in E. coli.
Localization
Nuclear
Specificity
Nijmegen breakage syndrome (NBS, nibrin) is an autosomal recessive chromosomal instability syndrome characterized by microcephaly, growth retardation, immunodeficiency, and cancer predisposition. Nbs1 Antibody (1D7) recognizes the 95kDa NBS protein which contains a fork FHA head-associated domain that is adjacent to BRCT, a breast cancer C terminal domain, that has been implicated in protein-protein interactions. NBS is member of the Mre11/Rad50, p400 double-strand break repair complex involved in double-strand break repair and cell-cycle checkpoint functions.

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 (NB100-221). (Showing 1 - 5 of 5 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. We are looking for an NBS mouse monoclonal antibody that would work for IF. NBS1 Antibody (NB100-221) might be ideal, except we need to use it in mouse cells, and the data sheet says it is reactive with human cells. Could you tell us if it has been tested in mouse cells? If it has not, we would be willing to test it, and send you verifying images. However, if we test it and it does not work in mouse cells, would we be able to receive another antibody in exchange? We would also like to purchase a STAT1 mouse monoclonal antibody that would work for IF. STAT1 Antibody (NBP1-48011). The species reactivity of the antibody indicates that it is reactive with human, canine, and primate cells. Has it been tested in mouse cells?
    • I have a couple of thoughts after reading through your needs for this antibody. This antibody is validated for mouse reactivity. I assume you realize that if you want to use a mouse mAb on mouse tissue, you will need to do a mouse on mouse block to prevent non-specific staining with your secondary. If you would like to test an antibody in an unvalidated species or application, please consider our Innovators Reward Program. STAT1, NBP1-48011, has not been validated for mouse reactivity so this would qualify for the Innovators Reward Program.
