Function: Component of the MRE11-RAD50-NBN (MRN complex) which plays a critical role in the cellular response to DNA damage and the maintenance of chromosome integrity. The complex is involved in double-strand break (DSB) repair, DNA recombination, maintenance of telomere integrity, cell cycle checkpoint control and meiosis. The complex possesses single-strand endonuclease activity and double-strand-specific 3'-5' exonuclease activity, which are provided by MRE11. RAD50 may be required to bind DNA ends and hold them in close proximity. NBN modulate the DNA damage signal sensing by recruiting PI3/PI4-kinase family members ATM, ATR, and probably DNA-PKcs to the DNA damage sites and activating their functions. It can also recruit MRE11 and RAD50 to the proximity of DSBs by an interaction with the histone H2AX. NBN also functions in telomere length maintenance by generating the 3' overhang which serves as a primer for telomerase dependent telomere elongation. NBN is a major player in the control of intra-S-phase checkpoint and there is some evidence that NBN is involved in G1 and G2 checkpoints. The roles of NBS1/MRN encompass DNA damage sensor, signal transducer, and effector, which enable cells to maintain DNA integrity and genomic stability. Forms a complex with RBBP8 to link DNA double-strand break sensing to resection. Enhances AKT1 phosphorylation possibly by association with the mTORC2 complex.
Subunit Structure: Component of the MRN complex composed of two heterodimers RAD50/MRE11 associated with a single NBN (PubMed:9590181, PubMed:9705271, PubMed:11238951). Component of the BASC complex, at least composed of BRCA1, MSH2, MSH6, MLH1, ATM, BLM, RAD50, MRE11 and NBN (PubMed:10783165). Interacts with histone H2AFX this requires phosphorylation of H2AFX on 'Ser-139' (PubMed:12419185). Interacts with HJURP (PubMed:17823411). Interacts with INTS3 (PubMed:19683501). Interacts with KPNA2 (PubMed:16188882). Interacts with TERF2 (PubMed:10888888). Interacts with RBBP8; the interaction links the role of the MRN complex in DNA double-strand break sensing to resection (PubMed:19759395). Interacts with SP100; recruits NBN to PML bodies (PubMed:12470659). Interacts with ATF2 (PubMed:15916964). Interacts with MTOR, MAPKAP1 isoform 2 and RICTOR; indicative for an association with the mTORC2 complex (PubMed:23762398). Interacts with MRNIP (PubMed:27568553).
Post-translational Modifications: Phosphorylated by ATM in response of ionizing radiation, and such phosphorylation is responsible intra-S phase checkpoint control and telomere maintenance.
Similarity: The FHA and BRCT domains are likely to have a crucial role for both binding to histone H2AFX and for relocalization of MRE11/RAD50 complex to the vicinity of DNA damage.The C-terminal domain contains a MRE11-binding site, and this interaction is required for the nuclear localization of the MRN complex.The EEXXXDDL motif at the C-terminus is required for the interaction with ATM and its recruitment to sites of DNA damage and promote the phosphorylation of ATM substrates, leading to the events of DNA damage response.
NCBI and Uniprot Product Information
Predicted: 85 kDa
NCBI Description
Mutations in this gene are associated with Nijmegen breakage syndrome, an autosomal recessive chromosomal instability syndrome characterized by microcephaly, growth retardation, immunodeficiency, and cancer predisposition. The encoded protein is a member of the MRE11/RAD50 double-strand break repair complex which consists of 5 proteins. This gene product is thought to be involved in DNA double-strand break repair and DNA damage-induced checkpoint activation. [provided by RefSeq, Jul 2008]

The NBN nbn (Catalog #AAA9600578) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Nibrin Antibody reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Nibrin can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunofluorescence (IF), Immunocytochemistry (ICC), ELISA (EIA). WB: 1:500-1:2000 IF/ICC: 1:100-1:500. Researchers should empirically determine the suitability of the NBN nbn for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Nibrin, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
