Research Interests
During intracellular transport, proteins destined for the plasma membrane, secretory vesicles and prelysosomes must be sorted from one another within the Golgi complex, and sent to their appropriate addresses. The long term goal of our research is to elucidate the molecular mechanisms by which proteins are targeted to specific and distinct compartments. We would like to understand how transport vesicles select their contents, bud off from an organelle, translocate through the cytoplasm to recognize their target, and then fuse with their target to deliver specific cargo molecules. We have established a cell free system that reconstitutes a specific intracellular transport step: transport of mannose 6-phosphate receptors from prelysosomes to the trans Golgi network (TGN). The reaction is ATP dependent, requires cytosolic transport factors, and efficient. We discovered a Ras-like GTPase, Rab9, is required for this process. We are now studying proteins responsible for the specific localization of Rab GTPases in human cells. We have also discovered a large set of proteins responsible for receptor recycling to the TGN, including a protein named TIP47 that works with Rab9 to help package mannose 6-phosphate receptors into transport vesicles, and a Golgi tether that is needed for vesicle docking.
