Research Areas

The aim of our research is to elucidate the advanced molecular mechanism of a functional complex of proteins in vivo (bio-multisome) from a viewpoint of structural biology in detail using microscopy freely. It has become clear the importance of bio-multisome which takes on the several events in cells. Therefore, we would establish the new technical approach that can elucidate the wide range of three-dimensional structures which overlook the configuration of bio-multisome reaching a cellular level from an atomic level, by the development of microscopic analyses such as electron crystallography, single particle analysis, electron tomography and light microscopy. These experimental attempts will provide critical insights into the dynamic structure, localization, and function of the bio-multisome in living cells.
