Descrição geral

Nibrin (NBS1) is made up of 754 amino acids.
NBS1 (Nibrin), also known as p95 protein of the meiotic recombination 11 homolog 1/DNA repair protein RAD50 (MRE11/RAD50) complex. NBS1 contains two domains found in the cell cycle checkpoint proteins forkhead-associated domain (FHA) and an adjacent breast cancer carboxyterminal domain (BRCT). NBS1 is one of the protein components of the double-strand break repair complex NBS1/MRE11/p50.


synthetic peptide corresponding to amino acids 692-706 of mouse NBS1 (nibrin), conjugated to KLH via an N-terminal added cysteine residue.


Anti-NBS1 (Nibrin) antibody has been used:
  • in immunofluorence
  • in immunoblotting
  • in immunoprecipitation

Ações bioquímicas/fisiológicas

NBS1 (Nibrin) was first isolated as a protein involved in DNA repair through analysis of mutations in patients with Nijmegen breakage syndrome (NBS). The majority of NBS patients bear a five base pairs deletion that leads to truncated NBS1, called 657del5. p95/NBS1 (nibrin) deficiency abrogates the formation of the MRE11/RAD50 ionizing radiation-induced foci, revealing a molecular link between DSB repair and cell cycle checkpoints activated by DNA damage.
Nibrin (NBS1) is involved in stabilizing genomes and has a role in development of cancers. It also takes part in the repair mechanism after double strand breaks in the DNA.
