摘要

蛋白磷酸酶2A(protein phosphatase 2A,PP2A)是一种丝/苏氨酸磷酸酶,由A、B、C共3种亚基组成。研究显示,PP2A可通过催化蛋白质的去磷酸化反应,参与多种酶及转录因子的调控,在能量代谢、DNA损伤与修复、蛋白质翻译、细胞周期调控和信号转导等方面发挥重要作用。该文就PP2A的结构与调控、对能量代谢的影响以及在相关疾病发生中的作用进行综述。

Abstract

Protein phosphatase 2A (PP2A) is a serine/threonine phosphatase consisting of three subunits, namely A, B and C. Studies have shown that PP2A plays an important role in energy metabolism, DNA damage and repair, protein translation, cell cycle regulation and signal transduction by catalyzing the dephosphorylation of proteins and participating in the regulation of a variety of enzymes and transcription factors. This article reviews the structure and regulation of PP2A, its effect on energy metabolism and the occurrence of related diseases.
