PMI2的研究进展

Research Progress of PMI2

在植物中,叶绿体运动以光依赖的方式来调节光合作用,该过程对于植物有效捕获光能和避免光损伤至关重要,虽然引起叶绿体运动的蛋白质已经有过报道,但是他们之间的相互作用尚不清楚。Plastid Movement Impaired2(PMI2)是经鉴定的调节叶绿体运动的蛋白质。PMI2在结构上具有长卷曲螺旋区域,该区域往往被认为是能够介导蛋白质与蛋白质之间相互作用的结构域。主要讲述了PMI2的基因、定位、表达、互作蛋白以及叶绿体运动等方面,并对以后的研究进行展望。

In plants,Chloroplasts move in a light-dependent manner to regulating photosynthesis is essential to maximize light capture and reduce photodamage. Although several proteins have been reported to be involved in chloroplast movement, any physical interaction among them was not found. Plastid Movement Impaired 2(PMI2)were indentified as regulate chloroplast movement protein, which has a long coiled-coild regions that often considered to mediated interaction between protein to protein. In this review, we discuss the gene、location、expression、interaction proteins and chloroplast movement of PMI2, and the future research is prospected.
