摘要

Repair of DNA double-strand breaks (DSB) is essential for cell survival. Two major pathways, the highly accurate homologous recombination (HR) repair and the more error-prone non-homologous end-joining (NHEJ) pathway, are engaged in these repair processes, and their relative contribution is dependent on the cell cycle. Phosphorylation events triggered by DNA damage response and checkpoint kinases, including ATM, ATR, DNA-PK, CHK1 and CHK2, are important signaling mechanisms during DSB repair. However, in order for DSB repair to proceed in a coordinated manner and to be completed, the phosphorylation of key proteins in the pathways needs to be reversed at specific steps by protein dephos-phorylation.
