a Ser/Thr protein phosphatase of the PP2C family. Inhibits the activation of p38 and JNK kinase cascades induced by environmental stresses. Can also dephosphorylate cyclin-dependent kinases and may play a role in cell cycle control. Overexpression of this phosphatase activates the expression of p53, leading to G2/M cell cycle arrest and apoptosis. Note: This description may include information from UniProtKB.
