细胞膜相联钙结合蛋白的结构和功能研究进展

摘要

细胞膜相联钙结合蛋白（PCaP）是定位于细胞膜上的一类新的Ca2+结合蛋白。简要综述了PCaP的蛋白结构、调控Ca2+/磷脂酰肌醇3-磷酸信号通路的分子机制、调节微管微丝稳定的能力，以及其在植物顶端生长极性中的功能研究进展。%The plasma-membrane associated cation-binding protein(PCaP) of Arabidopsis thaliana is a kind of cation-binding protein which is located in plasma membrane. In this review, we mainly describled the advances re-search on the protein structure, the molecular mechanism of regulating Ca2+/PtdInsP(phosphatidylinositol 3-phos-phate) signaling pathways, the ability of adjusting microtube, and its biological functions in plant tip growth polari-ty of PCaP.
