Kinase Classification: PPP PP2A※ PP2A family introduction PP2A, a family of PPP, is ubiquitously expressed in all eukaryotes. Three subunits compose this phosphatase holoenzyme, among which, subunit A is a 60-65 kDa structural component, B is a regulatory subunit and C is a 36-38 kDa catalytic subunit. The substrate specificity, spatial and temporal functions of PP2A is determined by regulatory subunit B. PP2A are involved in a lot of cellular processes such as cell cycle regulation, cell morphology and development. In addition, PP2A plays a critical role in regulation of specific signal transduction cascades (1).
