How the components of cell membranes, lipids, transmembrane proteins, and bound cytoskeleton proteins, are organized and how the interplay between their molecular 3D architecture and the surrounding membrane affects their function? Our Team addresses these general questions in the context of cell division, cell detoxification and inter-organelles communication. We combine cryo-electron microscopy, single particle analysis, cryo-tomography and novel in vitro membrane systems to decipher the architectures of both proteins and membrane. We integrate our results with data derived from functional analysis, physics of membranes and cell biology to unravel mechanisms at different spatial and temporal scales.
