The epithelial polarity programme (EPP) is organized in response to extracellular cues and executed through the establishment of an apical–basal axis, intercellular junctions, epithelial-specific cytoskeletal rearrangements and a polarized trafficking machinery. Recent studies have provided insights into the interactions of the EPP with the polarized trafficking machinery and how they regulate epithelial polarization and depolarization.
