Current Research and Scholarly Interests The goal of our research is to elucidate the molecular mechanisms by which proteins are targeted to specific membrane compartments. How do transport vesicles select their contents, bud, translocate through the cytoplasm, and then fuse with their targets? We study the Ras-like Rab GTPases--how they serve as master regulators of all receptor trafficking events. We also study how cells acquire cholesterol from the diet and from LDL.
