摘要 2C类蛋白磷酸酶(PP2C)是一类丝氨酸/苏氨酸残基蛋白磷酸酶,以单体酶的形式广泛存在于生物体中,参与多种信号途径。大量研究表明,植物PP2C负调控ABA信号转导途径及多种逆境胁迫转导途径。本文对高等植物PP2C的分类及其对多种逆境信号转导途径的调控功能研究进行了综述与展望。 PP2C-type protein phosphatases belong to a family of Ser-Thr protein phosphatases.They are kinds of monomeric enzymes that present in both prokaryotes and eukaryotes.Evidences indicated that PP2C was involved in the negative regulation of ABA signaling and several other stress signaling pathways.Category and the recent progress of PP2C in the regulation of stress signaling transduction pathway in plants were briefly summarized in this paper.
