RESEARCH AREA


Brief Introduction

We utilize cryo-electron microscopy (cryo-EM) to understand how biomolecules actually work. We are currently in a revolutionary era of structural biochemistry. Recent advances in cryo-EM, in particular in the improvement of electron direct detector coupled with the development of data analysis software, have revolutionized the field over the last a few years. As a result, the contributions of cryo-EM techniques to understand biological processes was recognized in the form of the Nobel Prize in Chemistry in 2017, which was awarded to the scientists who developed and advanced cryo-EM techniques. Together with other biochemical approaches, we study (1) prokaryotic transcription to uncover the fundamental mechanism of RNA synthesis, (2) eukaryotic transcription to understand the principles of gene regulation during RNA synthesis, and (3) the microbiome to reveal the beneficial interaction between eukaryotes and prokaryotes. We hope that our efforts deepen our understanding of life and that they benefit humans in harmony with other species on earth.
