个人简介

研究领域蛋白靶向与囊泡运输：细胞内合成的蛋白需要运输到细胞内特定空间或分泌到细胞外来发挥作用，蛋白的靶向需要蛋白自身的靶向信号、受体、运输途径、运输囊泡、细胞骨架等因素来调节。分泌途径调节蛋白分泌到细胞膜或细胞外，参与植物的生长发育和逆境应答等生理过程。目前我们对分泌途径的研究主要围绕一个小G蛋白RabE展开。RabE调节蛋白的分泌，参与植物对病原菌的应答反应。我们运用质谱和Y2H的方法筛选RabE互作蛋白，识别调节RabE活性的蛋白与RabE的效应蛋白，以期理解蛋白分泌调节的分子机理，以及分泌途径的具体生理功能。我们运用多种显微镜（包括confocal、超分辨、免疫电镜）在不同尺度上来识别细胞内的信号和动态过程，并研究细胞器和囊泡的生物形成。
储藏蛋白运输：种子内储藏有大量的蛋白，它们储存于细胞内的蛋白储藏液泡或蛋白体，对于储藏蛋白运输机制的理解可以帮助我们培育高营养品质的作物。目前我们主要以水稻和豆科植物为对象，研究种子发育过程中储藏蛋白的运输途径、分选信号、分选受体等内容。我们运用CRISPR/CAS9敲除特定的分选受体基因，研究水稻储藏蛋白的运输机理。
