The MRN (Mre11-Rad50-Nbs1) complex is well known for participating in DNA damage response pathways in all phases of cell cycle.Here we show that MRN constitutes a mitosis-specific complex, named mMRN, with a novel protein, MMAP.MMAP directly interacts with MRE 11, and is required for optimal stability of the MRN complex during mitosis.MMAP co-localizes with MRN in mitotic spindles, and MMAP-deficient cells display abnormal spindle dynamics and chromosome segregation similar to MRN-deficient cells.

DNA double-strand breaks can harbour different types of chemical moieties that differ from the canonical 5phosphate and 3hydroxyl at the ends.Cells are therefore endowed with a wide variety of enzymat
