title: Cytoskeleton functions in membrane traffic in polarized epithelial cells.
abstract: The complexity of membrane traffic in polarized epithelial cells between the Golgi complex and either the apical or basal-lateral membrane domain, and between different membrane domains (transcytosis) requires that vesicles leaving one membrane compartment efficiently and rapidly reach their (correct) destination. There is increasing evidence that microtubules, actin microfilaments and the membrane-cytoskeleton are involved in several aspects of vesicle transport and in the regulation of protein distributions in polarized epithelial cells. These possible functions are discussed in the context of the development and maintenance of cell polarity.
