研究領域與專長

本實驗室研究重點是細胞週期進程中的蛋白質交互作用及訊息傳遞，尤其是癌細胞和病毒感染方面。我們在INK4、Ki67、CHK2蛋白質的結構和功能研究中，為一些癌症的機制研究提供了新契機。此外，我們研究人類(例如MDC1)和酵母(Rad53及Dun1)FHA domain傳達的蛋白質和磷蛋白之間的反應訊息路徑及結構。本實驗室另一個計畫著重在DNA聚合酶催化反應機制和生化功能，包括人類DNA聚合酶beta及lambda和非洲豬瘟病毒(African swine fever virus, ASFV)所帶有的DNA聚合酶X。研究此酵素特性使我們更進一步了解DNA層次的損傷反應和修復。最近，在台灣蛋白質計劃的支持下，他一直積極從事使用時間分辨的系列飛秒X射線晶體學研究DNA光解酶的機制，以及將cryo-EM應用於酶學的反應機理研究。
