膜蛋白在细胞活动中承担了各种各样的重要生物学功能，例如光合作用中的光能吸收和转化，呼吸作用中的电子传递和氧化磷酸化，物质的跨膜转运，信号的跨膜转导和膜内的酶促反应（如蛋白质降解，脂的合成和水解等）的催化等等。据估计，原核和真核细胞基因组中大约有20-30%的阅读框编码膜蛋白，凸显膜蛋白研究的重要性。截止目前为止，蛋白质数据库 (Protein Data Bank) 中仅仅有1%左右的结构数据是属于膜蛋白的。膜蛋白的结构生物学研究大大落后于水溶性蛋白，主要是由于膜蛋白异源过量表达，纯化和结晶过程中存在着众多难以逾越的障碍。尽管如此，膜蛋白的结构生物学研究正在成为结构生物学领域的一个热门的前沿分支，吸引了越来越多的研究者加入，目前在国际上正处于一个加速发展的前期（http://blanco.biomol.uci.edu/Membrane_Proteins_xtal.html）。

我实验室的研究方向在于应用结构生物学为主的方法，如X-射线晶体学和冷冻电子显微学，研究不同体系膜蛋白的结构与功能，如参与渗透压调节的细菌机械敏感通道，磷脂生物合成和修饰的各种膜内酶，以及光合作用状态转换相关的膜蛋白复合物。目标是基于三维结构，对参与重要生物学过程的关键膜蛋白功能进行深入研究，阐明其发挥作用的分子机理。
