General annotation (Comments)

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 MRE11A. 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. Ref.11 Ref.16 Ref.20 Ref.27
Subunit structure	Component of the MRN complex composed of two heterodimers RAD50/MRE11A associated with a single NBN. Component of the BASC complex, at least composed of BRCA1, MSH2, MSH6, MLH1, ATM, BLM, RAD50 and MRE11A By similarity. Interacts with histone H2AFX this requires phosphorylation of H2AFX on 'Ser-139'. Interacts with HJURP, INTS3, KPNA2 and TERF2. Interacts with RBBP8; the interaction links the role of the MRN complex in DNA double-strand break sensing to resection. Ref.2 Ref.11 Ref.12 Ref.16 Ref.17 Ref.18 Ref.24 Ref.27 Ref.28
Subcellular location	Nucleus By similarity. Chromosome › telomere By similarity. Note: Localizes to discrete nuclear foci after treatment with genotoxic agents By similarity.
Tissue specificity	Ubiquitous. Expressed at high levels in testis.
Domain	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. Ref.19 The C-terminal domain contains a MRE11-binding site, and this interaction is required for the nuclear localization of the MRN complex. Ref.19 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. Ref.19
Post-translational modification	Phosphorylated by ATM in response of ionizing radiation, and such phosphorylation is responsible intra-S phase checkpoint control and telomere maintenance. Ref.13 Ref.14 Ref.15
Involvement in disease	Nijmegen breakage syndrome (NBS) [MIM:251260]: A disorder characterized by chromosomal instability, radiation sensitivity, microcephaly, growth retardation, immunodeficiency and predisposition to cancer, particularly to lymphoid malignancies. Note: The disease is caused by mutations affecting the gene represented in this entry. Breast cancer (BC) [MIM:114480]: A common malignancy originating from breast epithelial tissue. Breast neoplasms can be distinguished by their histologic pattern. Invasive ductal carcinoma is by far the most common type. Breast cancer is etiologically and genetically heterogeneous. Important genetic factors have been indicated by familial occurrence and bilateral involvement. Mutations at more than one locus can be involved in different families or even in the same case. Note: Disease susceptibility is associated with variations affecting the gene represented in this entry. Ref.34 Aplastic anemia (AA) [MIM:609135]: A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements. It is characterized by peripheral pancytopenia and marrow hypoplasia. Note: Disease susceptibility may be associated with variations affecting the gene represented in this entry. Defects in NBN might play a role in the pathogenesis of childhood acute lymphoblastic leukemia (ALL).
Miscellaneous	In case of infection by adenovirus E4, the MRN complex is inactivated and degraded by viral oncoproteins, thereby preventing concatenation of viral genomes in infected cells.
Sequence similarities	Contains 1 BRCT domain. Contains 1 FHA domain.
Sequence caution	The sequence AAI08651.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence starting in position 550. The sequence CAH56160.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
