The ATR-Chk1 pathway is critical for DNA damage responses and cell cycle progression.Chk 1 inhibition is more deleterious to cycling cells than ATR inhibition,raising questions about ATR and Chk1 functions in the absence of extrinsic replication stress.Here, we show that a key role of ATR in S phase is to coordinate RRM2 accumulation and origin firing.

Structure-specific nucleases play crucial roles in DNA replication and DNA repair.The mechanisms of their regulation are not fully understood.Recently we reported a fission yeast protein, Pxd1, that r
DNA double strand break is one of the most detrimental DNA damages, which must be repaired for the maintenance of genomic stability.Damage recognition by the Mre11-Rad50-Nbs1 complex is the earliest e
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
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,
