CC   -!- FUNCTION: Component of the MRE11-RAD50-NBN (MRN complex) which plays a
CC       critical role in the cellular response to DNA damage and the
CC       maintenance of chromosome integrity. The complex is involved in double-
CC       strand break (DSB) repair, DNA recombination, maintenance of telomere
CC       integrity, cell cycle checkpoint control and meiosis. The complex
CC       possesses single-strand endonuclease activity and double-strand-
CC       specific 3'-5' exonuclease activity, which are provided by MRE11. RAD50
CC       may be required to bind DNA ends and hold them in close proximity. NBN
CC       modulate the DNA damage signal sensing by recruiting PI3/PI4-kinase
CC       family members ATM, ATR, and probably DNA-PKcs to the DNA damage sites
CC       and activating their functions. It can also recruit MRE11 and RAD50 to
CC       the proximity of DSBs by an interaction with the histone H2AX. NBN also
CC       functions in telomere length maintenance by generating the 3' overhang
CC       which serves as a primer for telomerase dependent telomere elongation.
CC       NBN is a major player in the control of intra-S-phase checkpoint and
CC       there is some evidence that NBN is involved in G1 and G2 checkpoints.
CC       The roles of NBS1/MRN encompass DNA damage sensor, signal transducer,
CC       and effector, which enable cells to maintain DNA integrity and genomic
CC       stability. Forms a complex with RBBP8 to link DNA double-strand break
CC       sensing to resection. Enhances AKT1 phosphorylation possibly by
CC       association with the mTORC2 complex (By similarity).
CC       {ECO:0000250|UniProtKB:O60934}.
CC   -!- SUBUNIT: Component of the MRN complex composed of two heterodimers
CC       RAD50/MRE11 associated with a single NBN (By similarity). As part of
CC       the MRN complex, interacts with MCM9; the interaction recruits the
CC       complex to DNA repair sites (By similarity). Component of the BASC
CC       complex, at least composed of BRCA1, MSH2, MSH6, MLH1, ATM, BLM, RAD50,
CC       MRE11 and NBN (By similarity). Interacts with histone H2AX this
CC       requires phosphorylation of H2AX on 'Ser-139' (By similarity).
CC       Interacts with HJURP, INTS3, KPNA2 and TERF2 (By similarity). Interacts
CC       with RBBP8; the interaction links the role of the MRN complex in DNA
CC       double-strand break sensing to resection (By similarity). Interacts
CC       with SP100; recruits NBN to PML bodies (PubMed:12470659). Interacts
CC       with ATF2 (By similarity). Interacts with MTOR, MAPKAP1 isoform 2 and
CC       RICTOR; indicative for an association with the mTORC2 complex (By
CC       similarity). Interacts with MRNIP (By similarity). Interacts with UFL1;
CC       promoting UFL1 recruitment to double-strand breaks following DNA damage
CC       (By similarity). Interacts with CYREN (via XLF motif)
CC       (PubMed:30017584). {ECO:0000250|UniProtKB:O60934,
CC       ECO:0000269|PubMed:12470659, ECO:0000269|PubMed:30017584}.

CC       Q9R207; Q61216: Mre11; NbExp=2; IntAct=EBI-2014862, EBI-2014813;
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:O60934}. Nucleus,
CC       PML body {ECO:0000250|UniProtKB:O60934}. Chromosome, telomere
CC       {ECO:0000250|UniProtKB:O60934}. Chromosome
CC       {ECO:0000250|UniProtKB:O60934}. Note=Localizes to discrete nuclear foci
CC       after treatment with genotoxic agents. Acetylation of 'Lys-5' of
CC       histone H2AX (H2AXK5ac) promotes NBN/NBS1 assembly at the sites of DNA
CC       damage. {ECO:0000250|UniProtKB:O60934}.
CC   -!- TISSUE SPECIFICITY: High expression in the liver, heart and testis. Low
CC       expression in all other tissues analyzed. In the cerebellum the
CC       postmitotic Purkinje cells are marked specifically.
CC       {ECO:0000269|PubMed:10915761}.
CC   -!- DEVELOPMENTAL STAGE: A low level of expression is observed in all
CC       tissues. Highly specific expression was observed in organs with
CC       physiologic DNA double strand breakage (DSB), such as testis, thymus
CC       and spleen. Enhanced expression is also found at sites of high
CC       proliferative activity. These are the subventricular layer of the
CC       telencephalon and the diencephalon, the liver, lung, kidney and gut, as
CC       well as striated and smooth muscle cells in various organs.
CC       {ECO:0000269|PubMed:10915761}.
CC   -!- DOMAIN: The FHA and BRCT domains are likely to have a crucial role for
CC       both binding to histone H2AX and for relocalization of MRE11/RAD50
CC       complex to the vicinity of DNA damage. {ECO:0000250|UniProtKB:O60934}.
CC   -!- DOMAIN: The C-terminal domain contains a MRE11-binding site, and this
CC       interaction is required for the nuclear localization of the MRN
CC       complex. {ECO:0000250|UniProtKB:O60934}.
CC   -!- DOMAIN: The EEXXXDDL motif at the C-terminus is required for the
CC       interaction with ATM and its recruitment to sites of DNA damage and
CC       promote the phosphorylation of ATM substrates, leading to the events of
CC       DNA damage response. {ECO:0000250|UniProtKB:O60934}.
CC   -!- PTM: Phosphorylated by ATM in response of ionizing radiation, and such
CC       phosphorylation is responsible intra-S phase checkpoint control and
CC       telomere maintenance. {ECO:0000250|UniProtKB:O60934}.
