PPM1D, ID (PPM1D, WIP1, Protein phosphatase 1D, Protein phosphatase 2C isoform delta, Protein phosphatase magnesium-dependent 1 delta, p53-induced protein phosphatase 1)

The protein encoded by this gene is a member of the PP2C family of Ser/Thr protein phosphatases. PP2C family members are known to be negative regulators of cell stress response pathways. The expression of this gene is induced in a p53-dependent manner in response to various environmental stresses. While being induced by tumor suppressor protein TP53/p53, this phosphatase negatively regulates the activity of p38 MAP kinase, MAPK/p38, through which it reduces the phosphorylation of p53, and in turn suppresses p53-mediated transcription and apoptosis. This phosphatase thus mediates a feedback regulation...
