Function
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. 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, which is required for single-strand invasion and recombination.
