Phosphorylation of PNKP by ATM prevents its proteasomal degradation and enhances resistance to oxidative stress.
We examined the mechanism regulating the cellular levels of PNKP, the major kinase/phosphatase involved in the repair of oxidative DNA damage, and find that it is controlled by ATM phosphorylation and ubiquitylation-dependent proteasomal degradation. We discovered that ATM-dependent phosphorylation...
