title: Intracellular trafficking of raft/caveolae domains: insights from integrin signaling.
abstract: Cells have a complex system for delivering and compartmentalizing proteins and lipids in order to achieve spatio-temporal coordination of signaling. Rafts/caveolae are plasma membrane microdomains that regulate signaling pathways and processes such as cell migration, polarization and proliferation. Regulation of raft/caveolae trafficking involves multiple steps regulated by different proteins to ensure coordination of signaling cascades. The best studied raft-mediated endocytic route is controlled by caveolins. Recent data suggest integrin-mediated cell adhesion is a key regulator of caveolar endocytosis. In this review we examine the regulation of caveolar trafficking and the interplay between integrins, cell adhesion and caveolae internalization.
