Wei Guo is an accomplished researcher affiliated with the Department of Biology at the Perelman School of Medicine, University of Pennsylvania. His research primarily focuses on understanding the molecular mechanisms of membrane trafficking events, particularly exocytosis and its role in cellular processes such as cell polarity, morphogenesis, and cancer metastasis. By using a combination of biochemistry, molecular biology, and genetics, Wei investigates the exocyst complex—a multi-protein machine essential for secretory vesicle docking and fusion at the plasma membrane. His studies reveal how the exocyst, consisting of eight proteins, is localized to regions of active exocytosis and plays a critical role in polarized growth in various cell types, including yeast and mammalian cells. Wei is particularly interested in how the assembly and function of the exocyst complex are influenced by small GTPases and cytoskeletal interactions, aiming to uncover the intricate coordination of cellular machinery involved in key biological functions such as morphogenesis and migration. His work contributes to a deeper understanding of the cellular underpinnings of diseases, including cancer and polycystic kidney disease.
