研究領域

我們實驗室主要用生物物理工具和化學生物手段探討控制人類遺傳訊息傳遞和修復的蛋白質巨分子。目前我們專注的課題包括:核醣核酸聚合酶與它的轉錄因子所形成的複合結構,核醣核酸聚合酶被泛素修飾的機制,流感和手口足病毒結構的解析和侵入細胞的機理。我們使用的工具有低溫電子顯微鏡影像重建,單分子螢光能共振顯微術,和酵母菌分子生物學。電子顯微鏡可以幫助我們得到次奈米的結構,而螢光顯微鏡可以幫助我們得到這些分子的動態。為了有效從事電子顯微鏡和螢光顯微鏡造影,我們也用化學生物共軛方法把奈米金和染劑接到蛋白質上。我們歡迎具有合成化學、生物學、物理學、數學和電機工程背景的年輕人參與我們的團隊,一起作好玩的實驗。
