Auto-regulatory Mechanisms of Phosphorylation of Checkpoint Kinase 1 (Chk1)

Chk1, a serine/threonine protein kinase, is centrally involved in cell cycle checkpoints and cellular response to DNA damage. Phosphorylation of Chk1 at two Ser/Gln (SQ) sites, Ser-317 and Ser-345, by the upstream kinase ATR is critical for checkpoint activation. However, the precise molecular mecha...
