Background: Nbs1

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).
