My research is directed toward elucidation of the roles of the cytoskeleton in the formation and maintenance of cell polarity. Not only is the cytoskeleton a scaffold crucial to cell shape, it also serves as the tracks or highways upon which cell components are delivered to their correct cellular destinations. The constituents of the apical cytoskeleton and plasma membrane are important in the physiology of polarized intestinal epithelial cells. I have found that myosin-I, a nonmuscle actin-based motor, and dynein, a microtubule-based motor, are bound to Golgi-derived vesicles and may be important in the targeting and delivery to the apical plasma membrane domain. The mistargeting of plasma membrane proteins can cause illnesses such as microvillus inclusion disease and polycystic kidney disease, therefore, an understanding of delivery mechanisms may provide therapeutic tools.
