CC -!- FUNCTION: Component of the MRN complex, which plays a central role in
CC double-strand break (DSB) repair, DNA recombination, maintenance of
CC telomere integrity and meiosis. The complex possesses single-strand
CC endonuclease activity and double-strand-specific 3'-5' exonuclease
CC activity, which are provided by MRE11. RAD50 may be required to bind
CC DNA ends and hold them in close proximity. This could facilitate
CC searches for short or long regions of sequence homology in the
CC recombining DNA templates, and may also stimulate the activity of DNA
CC ligases and/or restrict the nuclease activity of MRE11 to prevent
CC nucleolytic degradation past a given point. The complex may also be
CC required for DNA damage signaling via activation of the ATM kinase. In
CC telomeres the MRN complex may modulate t-loop formation.
CC {ECO:0000250|UniProtKB:P49959}.
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC -!- ACTIVITY REGULATION: Interaction with SAMHD1 stimulates the double-
CC strand-specific 3'-5' exonuclease activity.
CC {ECO:0000250|UniProtKB:P49959}.
CC -!- SUBUNIT: Component of the MRN complex composed of two heterodimers
CC RAD50/MRE11 associated with a single NBN. As part of the MRN complex,
CC interacts with MCM9; the interaction recruits the complex to DNA repair
CC sites. Component of the BASC complex, at least composed of BRCA1, MSH2,
CC MSH6, MLH1, ATM, BLM, RAD50, MRE11 and NBN. Found in a complex with
CC TERF2. Interacts with DCLRE1C/Artemis and DCLRE1B/Apollo. Interacts
CC with ATF2. Interacts with EXD2. Interacts with MRNIP. Interacts with
CC SAMHD1; leading to stimulate 3'-5' exonuclease activity. Interacts
CC (when ubiquitinated) with UBQLN4 (via its UBA domain) (By similarity).
CC Interacts with CYREN (via XLF motif) (By similarity).
CC {ECO:0000250|UniProtKB:P49959, ECO:0000250|UniProtKB:Q61216}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P49959}.
CC Chromosome, telomere {ECO:0000250|UniProtKB:P49959}. Chromosome
CC {ECO:0000250|UniProtKB:P49959}. Note=Localizes to discrete nuclear foci
CC after treatment with genotoxic agents. {ECO:0000250|UniProtKB:P49959}.
CC -!- PTM: Ubiquitinated following DNA damage. Ubiquitination triggers
CC interaction with UBQLN4, leading to MRE11 removal from chromatin and
CC degradation by the proteasome. {ECO:0000250|UniProtKB:P49959}.
CC -!- SIMILARITY: Belongs to the MRE11/RAD32 family. {ECO:0000305}.
