We are interested in understanding mechanisms of vesicular transport and are also applying these insights to elucidating physiology and disease mechanisms. Coat proteins initiate, and thereby define, intracellular transport pathways. We have identified a novel coat complex for endocytic recycling, a pathway critical for many cellular events. At a more fundamental level, we have found that coat complexes cooperate with critical lipids to “bend” the membrane bilayer in achieving vesicle formation. Our insights have also led us to elucidate molecular mechanisms that underlie cell migration, metabolic homeostasis, and viral pathogenesis.
