| Post Translational Modifications | Phosphorylated by ATM at Ser-676 and Ser-678 in response to DNA damage, promoting MRE11 activity: phosphorylation activates MRE11 by preventing the interaction between MRE11 and the C1QBP inhibitor. Phosphorylation at Ser-649 by PLK1 primes for phosphorylation at Ser-688 by CK2, inhibiting recruitment of the MRN complex to DNA damage sites. Asymmetric dimethylation by PRMT1 promotes MRE11 exonuclease activity. Lactylation at Lys-673 by CREBBP/CBP in response to DNA damage promotes DNA binding and MRE11 activity. Acetylated on lysine residues by KAT2A /GCN5. Ubiquitinated following DNA damage. Ubiquitination triggers interaction with UBQLN4, leading to MRE11 removal from chromatin and degradation by the proteasome. Ubiquitinated at Lys-339 and Lys-480 by RNF126 via 'Lys-27'- and 'Lys-29'-linked polyubiquitin chains, promoting the exonuclease activity of MRE11. SUMOylated by PIAS1, stabilizing MRE11 on chromatin during end resection. DeSUMOylated by SENP3 following removal from DNA double-strand breaks (DSBs). Ufmylation at Lys-282 promotes MRE11 activity and is required for activation of the ATM and ATR kinases by the MRN complex. (Microbial infection) Following infection by adenovirus E4, ubiquitinated and degraded by a SCF-like E3 ubiquitin ligase complex containing viral proteins E1B-55K and E4-ORF6. |
| Function | Core component of the MRN complex, which plays a central role in double-strand break (DSB) repair, DNA recombination, maintenance of telomere integrity and meiosis. 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. 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. Within the MRN complex, MRE11 possesses both single-strand endonuclease activity and double-strand-specific 3'-5' exonuclease activity. After DSBs, MRE11 is loaded onto DSBs sites and cleaves DNA by cooperating with RBBP8/CtIP to initiate end resection. MRE11 first endonucleolytically cleaves the 5' strand at DNA DSB ends to prevent non-homologous end joining (NHEJ) and licence HR. It then generates a single-stranded DNA gap via 3' to 5' exonucleolytic degradation to create entry sites for EXO1- and DNA2-mediated 5' to 3' long-range resection, which is required for single-strand invasion and recombination. RBBP8/CtIP specifically promotes the endonuclease activity of MRE11 to clear protein-DNA adducts and generate clean double-strand break ends. The MRN complex is also required for DNA damage signaling via activation of the ATM and ATR kinases: the nuclease activity of MRE11 is not required to activate ATM and ATR. The MRN complex is also required for the processing of R-loops. The MRN complex is involved in the activation of the cGAS-STING pathway induced by DNA damage during tumorigenesis: the MRN complex acts by displacing CGAS from nucleosome sequestration, thereby activating it. In telomeres the MRN complex may modulate t-loop formation. MRE11 contains two DNA-binding domains (DBDs), enabling it to bind both single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA). |
