General description

Monoclonal Anti-NBS1 (Nibrin) (mouse IgG1isotype) is derived from the hybridoma NBS1-501 produced by the fusion of mouse myeloma cells (NS1 cells) and splenocytes from BALB/c mice immunized with a synthetic peptide of human NBS1. Nibrin is mapped to human chromosome 8q21.3. The encoded protein has two domains found in the cell cycle checkpoint proteins, forkhead-associated domain (FHA), and an adjacent breast cancer carboxy-terminal domain (BRCT).

Immunogen

synthetic peptide corresponding to amino acids 206-220 of human NBS1.

Application

Monoclonal Anti-NBS1 (Nibrin) antibody produced in mouse has been used in:
  • antibody microarray
  • immunocytochemistry
  • immunoblotting
  • immunoprecipitation
  • enzyme linked immunosorbent assay (ELISA)

Biochem/physiol Actions

NBS1(Nibrin) was first isolated as a protein involved in DNA repair through analysis of mutations in patients with this syndrome. p95/NBS1(Nibrin) deficiency abrogates the formation of the Meiotic recombination 11 homolog 1(MRE11) / DNA repair protein RAD50 ionizing radiation-induced foci, revealing a molecular link between double-stranded break repair (DSB) and cell cycle checkpoint functions. The phenotypic similarities between ataxia-telangiectasia (AT) and Nijmegen breakage syndrome had suggested that ataxia-telangiectasia mutated gene (ATM) and NBS1 functions in a common signaling pathway. This was confirmed by the finding that in response to ionizing radiation, NBS1is phosphorylated in Ser343 in an ataxia-telangiectasia mutated ATM-dependent manner.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide.

MRE11, RAD50 and NBS1 form a highly conserved protein complex (the MRE11 complex) that is involved in the detection, signalling and repair of DNA damage. We identify MDC1 (KIAA0170/NFBD1), a protein that contains a forkhead-associated (FHA) domain and two BRCA1
