　　RNA分子在蛋白质翻译、RNA修饰和加工、基因调控等多种过程中发挥着重要的作用。我们实验室的主要兴趣集中在和RNA生物学相关的结构研究，包括真核生物核糖体的组装、RNA修饰和RNA沉默等领域，主要使用X射线晶体学、电镜、核磁共振、生化、酵母遗传操作等技术手段。

　　1. 真核生物核糖体组装

　　蛋白质工厂——核糖体是由RNA和蛋白质组成的超级复合物，它在体内的组装需要经历高度复杂的过程。在出芽酵母Saccharomyces cerevisiae中，有200多个保守的蛋白质组装因子和大量非编码RNA参与核糖体的组装。我们以出芽酵母为模式生物，研究核糖体体内组装的分子过程、组装因子的结构和功能以及核糖体前体的结构。

　　2. H/ACA和C/D RNA蛋白质复合物

　　H/ACA 和 C/D RNA是两大类古老的非编码RNA，它们和蛋白质结合形成多元复合物，主要在RNA的假尿嘧啶合成和2'-O甲基化修饰中，发挥结合特异底物的向导作用。我们研究H/ACA和C/D 两类RNA蛋白质复合物的空间结构、生化机制和生物发生过程。

　　3. RNA沉默

　　多种小RNA(siRNA, miRNA, crRNA)作为特异性决定因子在真核和原核生物中控制着基因的沉默。我们研究这些小RNA的加工、调控机制和效应复合物。
