科研方向
高寧實驗室主要致力於闡明細胞內大型蛋白-核酸複合物形成的分子機器的精細結構及工作分子機制，近年來的科研工作著重於核糖體的生物生成（ribosome biogenesis）、蛋白質生物合成的調控、DNA複製起始調控等重要基礎生物學過程。實驗室主要採用冷凍電鏡三維重構的方法分析大型複合物的高分辨結構，輔助遺傳學、細胞生物學、生化分子生物學手段回答大分子機器在功能執行過程中的機制性問題。同時，針對結構課題中的技術難點，實驗室還致力於冷凍電鏡方法學的研究，包括樣品製備技術和算法的改進等。目前關注的一些基礎生物學領域包括：
1. Ribosome biogenesis and translation regulation.
2. Structure and mechanisms of DNA replication machinery.
3. Structural and functional study of Long non-coding RNA.
運用冷凍電鏡三維重構技術和生物化學及分子生物學手段進行生物大分子複合物的結構與功能研究。現有的工作重點包括原核和真核核糖體體內組裝的機制和調控以及蛋白翻譯的調控機制研究。
科學研究
2016年12月，高寧課題組和合作者在《Nature》（Doi:10.1038/nature20822）發表研究論文，報導了細菌中non-stop mRNA在核糖體上的翻譯終止狀態複合物的高分辨冷凍電鏡結構，並揭示了ArfA在non-stop mRNA翻譯終止過程中的作用機制；他們在體外組裝了ArfA/RF2、non-stop mRNA、tRNA與70S核糖體的複合物，並獲得了該複合物的高分辨冷凍電鏡結構，結構表明ArfA C端的loop結合於核糖體30S小亞基上的mRNA進入通道，並占據了終止密碼子的部分結合位點，而N端則直接與30S解碼中心及RF2相互作用。進一步分析表明ArfA扮演了兩個重要角色：N端作為mRNA長度的感受器，如果核糖體尚未行進到mRNA的3’末端，mRNA進入通道內的核苷酸會阻礙ArfA的結合；C端則通過和RF2直接結合，從功能上補償了終止密碼子對RF2的激活效應。該研究展示了具有極大結構柔性的小蛋白可以通過結構模擬來取代mRNA上的三鹼基終止密碼子的功能。
