摘要: 钙调素作为细胞内主要的Ca2+传感蛋白, 通过与不同的钙调素结合蛋白的结合传递钙信号, 调控细胞生理和生长发育过程。IQ基序(IQxxxRGxxxR, Pfam 00612)是少数几个钙调素与钙调素结合蛋白结合的结构域之一。植物具IQ基序的钙调素结合蛋白包括IQM、IQD、CAMTA、CNGC和myosin 5个家族及少数其它蛋白。该文综述了植物具IQ基序的钙调素结合蛋白的类型、结构特点和功能等方面的研究进展, 并对今后的研究进行了展望。

Abstract: As the primary intracellular calcium sensors, calmodulins regulate different cellular physiologic, growth and development processes by binding to different calmodulin-binding proteins. The IQ motif, IQxxxRGxxxR (Pfam 00612), is one of a few recognition motifs for calmodulins in calmodulin-binding proteins. As well as a few other proteins, 5 major families, including IQM, IQD, CAMTA, CNGC and myosin family, have been found to possess the IQ motif(s) in plants. Here, we review the research progress in plant IQ motif-containing calmodulin-binding proteins, including their type, structural characteristics and function, and prospects for future study.
