Background NBS1 (Nijmegen breakage syndrome protein 1) is a component of MRN complex (Mre11-Rad50-Nbs1) that plays important role in detection and signaling of DNA double strand breaks (DSBs) through acting as DSB sensor, co-activator of DSB-induced cell cycle checkpoint signaling, and as repair-effector in two competing DSB repair pathways: homologous recombination (HR) and non-homologous end-joining (NHEJ). MRN complex also associates with telomeres at the ends of linear chromosomes, where it contributes to their maintenance. NBS1's FHA domain binds phospho-Thr residues in Ser-X-Thr motifs present in DNA damage proteins, including Mdc1 and Ctp1, whereas, BRCT domains of NBS1 bind Ser-X-Thr motifs when Ser residue is phosphorylated. These phospho-dependent interactions are important for recruiting repair and checkpoint proteins to DSB sites and NBS1 is responsible for MRN complex's nuclear translocation. NBS1 itself does not possess enzymatic activity and contributes to DSB repair primarily by mediating protein-protein interactions at DNA breakage sites. The central region of NBS1 1 possesses several SQ motifs that are phosphorylated by ATM kinase via DNA damage response. NBS1's C-terminus contains a domain that interacts with ATM and recruits it to DSBs, and induces apoptosis in response to damage. DSBs can be caused by ionizing radiation, certain chemotherapy drugs, metabolic ROS, as errors during replication, by programmed enzymatic activities during meiosis/V(D)J recombination etc., and if left unrepaired, DSBs can generate chromosomal translocations, aneuploidy and carcinogenesis.
