Cellular structural biology and imaging

Using core stengths in electron tomography and protein bioengineering the cellular structural biology  group focuses on analysis of 3D structures of biological macromolecules in the cell, in particular using cryo-electron tomography.

Our Research

Our focus is electron and X-ray imaging and related methodological development. Takashi Ishikawa is interested in eukaryotic cilia/flagella, which are microtubule-based organelles and enable cellular motility, extracellular flow as well as sensing. His group pursues 3D imaging of motor, regulatory, and cytoskeletal proteins, intact cilia and ciliated cells and tissues, employing single particle cryo-EM, cryo-electron tomography and ptychographic X-ray tomography. Their aim is to reveal molecular mechanism of ciliary function. The Benoit group is interested in molecular and cellular structures of membrane proteins, especially receptors. They use single particle cryo-EM to analyze molecular structure of membrane proteins, developing related genetic engineering techniques.
