Description: Dr. Pollard uses biophysical analysis of purified proteins and observations of live cells to study cellular motility and cytokinesis. Arp2/3 complex nucleates branched actin filaments that push forward the leading edge of motile eukaryotic cells and cortical actin patches in fungi. Cooperative binding of WASp/Scar nucleation promoting factors, the first actin subunit in the daughter filament and mother filaments activate Arp2/3 complex to form branches. Some of these events can be visualized and quantitated in real time in fission yeast actin patches.
