Title: Dissecting the molecular mechanisms that regulate intracellular membrane fusion.
Abstract: In eukaryotic cells, membrane-bound vesicles carry protein and membrane cargo to the plasma membrane for exocytosis. The precise spatial and temporal regulation of vesicle fusion is achieved by a large multi-subunit tethering complex called the exocyst complex. Exocyst interacts with the SNARE membrane fusion proteins and a variety of regulatory proteins. Our in vitro biochemical and biophysical studies indicate that exocyst provides extensive chaperoning functions across the entire process of SNARE complex assembly and fusion. Exocyst proceeds through a series of activating conformational changes in order to efficiently tether vesicles, bind to SNAREs and accelerate membrane fusion.
