Mechanobiology of membrane remodeling
Dr. Michal Skruzny
Every cell (either microbial, human or eventual artificial one) has to actively reshape its membranes. To understand general principles of membrane reshaping we look at endocytosis in yeast, which provides conserved and well amenable model of membrane remodeling. Specifically, we study how forces are transmitted by endocytic proteins to bend the membrane efficiently. We also characterize the nanoscale architecture of endocytic protein machinery to understand how it evolved towards a robust membrane-remodeling machine. To achieve that, we use advanced fluorescence microscopy (FRET techniques and biosensors, multicolor live-cell imaging), yeast genetics and biochemistry. Our studies should help to formulate biomechanical principles of membrane remodeling not only during endocytosis, but also in other key cellular processes like membrane trafficking, cell morphogenesis and motility, or pathogen invasion.
