報告題目:Cryo-Electron Microscopy: From Visualizing Complex Dynamics to Therapeutic Discovery(冷凍電子顯微鏡:從復合動力學分析到靶向藥物探索)
報告時間:2019年5月30日下午3:00-4:00
報告地點:東區(qū)教學綜合樓B702
報告摘要:
Cryo-electron microscopy (cryo-EM) is transforming structural and chemical biology. The nature of cryo-EM single-particle images posits themselves being amenable to the theory and approaches previously developed for non-equilibrium statistical mechanics. Thus, it is possible that the principles and methodology in non-equilibrium statistical mechanics may transform the cryo-EM approach to enable its capability in solving complex dynamics of many-subunit system like 26S proteasome. In this talk, I will briefly outline the several lines of method development undergoing in my group that attempt to apply non-equilibrium statistical mechanical techniques to push the envelope of cryo-EM in analyzing extremely heterogenous systems at the atomic level. On the basis of these technological development, I will describe how we made several major breakthroughs in analyzing the substrate-degradation dynamics of human proteasome and in visualizing the intermediate NEK7-licensing step during NLRP3 inflammasome activation. These studies collectively highlight the ongoing transformation of cryo-EM from a key atomic imaging approach to an indispensable therapeutic discovery tool that might revolutionize molecular medicine in the future.
