Component of the MRN complex, which plays a central role in double-strand break (DSB) repair, DNA recombination, maintenance of telomere integrity and meiosis (PubMed:10888888, PubMed:15616588, PubMed:18411307, PubMed:18583988, PubMed:18678890, PubMed:19759395, PubMed:23115235, PubMed:28216226, PubMed:28867292, PubMed:9705271). The MRN complex is involved in the repair of DNA double-strand breaks (DSBs) via homologous recombination (HR), an error-free mechanism which primarily occurs during S and G2 phases (PubMed:19759395, PubMed:28867292, PubMed:9705271). The complex (1) mediates the end resection of damaged DNA, which generates proper single-stranded DNA, a key initial steps in HR, and is (2) required for the recruitment of other repair factors and efficient activation of ATM and ATR upon DNA damage (PubMed:19759395, PubMed:9705271). The MRN complex possesses single-strand endonuclease activity and double-strand-specific 3'-5' exonuclease activity, which are provided by MRE11, to initiate end resection, which is required for single-strand invasion and recombination (PubMed:19759395, PubMed:28867292, PubMed:9705271). Within the MRN complex, NBN acts as a protein-protein adapter, which specifically recognizes and binds phosphorylated proteins, promoting their recruitment to DNA damage sites (PubMed:12419185, PubMed:15616588, PubMed:18411307, PubMed:18582474, PubMed:18583988, PubMed:18678890, PubMed:19759395, PubMed:19804756, PubMed:23762398, PubMed:24534091, PubMed:27814491, PubMed:27889449, PubMed:33836577). Recruits MRE11 and RAD50 components of the MRN complex to DSBs in response to DNA damage (PubMed:12419185, PubMed:18411307, PubMed:18583988, PubMed:18678890, PubMed:24534091, PubMed:26438602). Promotes the recruitment of PI3/PI4-kinase family members ATM, ATR, and probably DNA-PKcs to the DNA damage sites, activating their functions (PubMed:15064416, PubMed:15616588, PubMed:15790808, PubMed:16622404, PubMed:22464731, PubMed:30952868, PubMed:35076389). Mediates the recruitment of phosphorylated RBBP8/CtIP to DSBs, leading to cooperation between the MRN complex and RBBP8/CtIP to initiate end resection (PubMed:19759395, PubMed:27814491, PubMed:27889449, PubMed:33836577). RBBP8/CtIP specifically promotes the endonuclease activity of the MRN complex to clear DNA ends containing protein adducts (PubMed:27814491, PubMed:27889449, PubMed:30787182, PubMed:33836577). The MRN complex is also required for the processing of R-loops (PubMed:31537797). NBN also functions in telomere length maintenance via its interaction with TERF2: interaction with TERF2 during G1 phase preventing recruitment of DCLRE1B/Apollo to telomeres (PubMed:10888888, PubMed:28216226). NBN also promotes DNA repair choice at dysfunctional telomeres: NBN phosphorylation by CK2 promotes non-homologous end joining repair at telomeres, while unphosphorylated NBN promotes microhomology-mediated end-joining (MMEJ) repair (PubMed:28216226). Enhances AKT1 phosphorylation possibly by association with the mTORC2 complex (PubMed:23762398).

The target known as p95/NBS1 also referred to as NBN protein is a critical component in the DNA damage response mechanism. The full molecular weight of the NBS1 protein is approximately 95 kDa. This protein is abundantly expressed in various tissues particularly where there is a higher rate of cell division or repair such as in the thymus and testis. It plays an important role in maintaining the stability of the genome through its involvement in the repair of double-strand breaks.
The NBS1 protein functions as an essential component of the MRN complex which also includes MRE11 and RAD50 proteins. This complex is fundamental in accurately detecting DNA double-strand breaks and initiating repair processes. Through its actions NBS1 facilitates numerous cellular processes that preserve genomic integrity such as homologous recombination and non-homologous end joining. Its influence in controlling the cell cycle further emphasizes its role in maintaining cellular health.
The NBS1 protein engages significantly in the DNA damage response and repair pathways notably impacting the ATM signaling pathway. By interacting with proteins such as ATM kinase NBS1 facilitates the phosphorylation and activation of several downstream effectors necessary for DNA repair and cell cycle checkpoints. The MRN complex also links with the RAD50 protein highlighting its involvement in these pathways.
Mutations in the NBS1 gene are linked to Nijmegen breakage syndrome characterized by sensitivity to radiation immune deficiency and increased cancer risk. Additionally NBS1's role in pathways makes it pertinent to certain cancer pathologies where its malfunction can contribute to genomic instability. The NBN protein through its interaction with ATM and RAD50 assists in understanding its connection with predispositions to these diseases.
