运用冷冻电镜三维重构技术和生物化学及分子生物学手段进行生物大分子配位化合物的结构与功能研究。现有的工作重点包括原核生物和真核生物核糖体体内组装的机制和调控以及蛋白翻译的调控机制研究。
科学研究
2016年12月，高宁课题组和合作者在《自然》（Doi:10.1038/nature20822）发表研究论文，报道了细菌中non-stop mRNA在核糖体上的翻译终止状态复合物的高分辨冷冻电镜结构，并揭示了ArfA在non-stop mRNA翻译终止过程中的作用机制；他们在体外组装了ArfA/RF2、non-stop mRNA、转运RNA与70S核糖体的配位化合物，并获得了该复合物的高分辨冷冻电镜结构，结构表明ArfA C端的loop结合于核糖体30S小亚基上的mRNA进入通道，并占据了终止密码子的部分结合位点，而N端则直接与30S解码中心及RF2相互作用。进一步分析表明ArfA扮演了两个重要角色：N端作为mRNA长度的感受器，如果核糖体尚未行进到mRNA的3’末端，mRNA进入通道内的核苷酸会阻碍ArfA的结合；C端则通过和RF2直接结合，从功能上补偿了终止密码子对RF2的激活效应。该研究展示了具有极大结构柔性的小蛋白可以通过结构模拟来取代mRNA上的三碱基终止密码子的功能。
