摘　　要：钙调素(CaM)作为最重要的一类Ca^(2+)传感蛋白可以通过与其下游CaM结合蛋白(CaMBP)作用而调节细胞的生理功能。因此,对CaMBP的研究是揭示CaM作用机制的重要内容,是探明Ca^(2+)-CaM信号转导系统的关键。该文从CaMBP和CaM的结合特性、植物CaMBP的分布以及植物CaMBP的生物学功能等方面综述了植物CaMBP的研究现状和最新进展。The important Ca^(2+)-sensing protein, calmodulin(CAM), plays its role in regulating cellular responses by activating specific CaM-binding proteins(CaMBPs), and therefore the study of the latter is an important way to know the mechanism of CaM and elucidate the Ca^(2+)-CaM signal transduction pathway. More than fifty kinds of CaMBPs have been identified in plant kingdom. CaMBPs are distributed in all plant species and all kinds of tissues; they are involved in many biological responses during the processes of growth and development, metabolism regulation and cell division, such as responses to phytohormones, to stress, and to pathogen, and transcription activation. This review summarizes the recent progress on the interaction of CaMBPs with CaM, their distribution, their subcellular localization, and involvement in biological functions.
