摘要:

钙离子(Ca2+)是一种重要的第二信使, 参与调节植物的生长发育和对环境的适应。钙调素(CaM)和类钙调蛋白(CML)是一类最主要的Ca2+感受器, 虽然其自身没有催化活性, 但可通过调节下游靶蛋白的活性, 进而调控细胞的各种生理活动。该文总结了植物体内CaM结合蛋白(CBP)的生理功能、鉴定方法和调控机理, 以及CaM介导的信号转导途径, 包括蛋白磷酸化与去磷酸化、基因转录、离子运输、活性氧代谢、激素和磷脂信号等, 并对今后的研究方向进行了展望。

Abstract:

Calcium (Ca2+) is an important second messenger in plant responses to diverse cellular and environmental stimuli. Calmodulin (CaM) and calmodulin-like proteins (CMLs) are major Ca2+ sensors to decode Ca2+ signals. Although CaM and CMLs have no enzymatic activity or biochemical functions, they are considered multifunctional regulatory proteins by regulating the activity of various classes of downstream CaM/CML-binding proteins (CBPs) and therefore are involved in multiple cellular processes during plant growth and development and environmental adaptation. In this review, we summarize studies of plant CBPs and their physiological functions, methods for identifying CBPs, mechanisms of CBP regulation by Ca2+/CaMs, and CaM-mediated signal transduction pathways related to protein phosphorylation and dephosphorylation, transcriptional regulation of gene expression, ion transportation, reactive oxygen species metabolism, hormone and phospholipid signals, the possible future directions are also discussed.
