Phosphatase Classification: Fold PPM (PP2C): Superfamily PPM (PP2C): Family PPM (PP2C): Subfamily PPM1D (WIP1)
Contents
Evolution
PPM1D (WIP1) most likely emerged in holozoa. It is single copy in most genomes, including human genome. See internal gOrtholog database.
Domain
PPM1D (WIP1) has a single structure domain, the phosphatase domain of PPM (PP2C) fold.
Function
PPM1D is also known as WIP1 (Wild-type p53-induced phosphatase 1). It 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. It is therefore involved in diverse pathways. Below are some examples of its functions:
PPM1D (WIP1) is highly expressed in HSCs but decreases with age, and WIP1-deficient (Wip1-/-) mice exhibited multifaceted HSC aging phenotypes, including the increased pool size and impaired repopulating activity [1].
