Vesicle-mediated membrane traffic has long been considered to be a constitutive process that is not burdened by layers of regulation. This contrasts with transmembrane signalling systems at the plasma membrane which relay information (i.e. extracellular stimuli) from the cell surface to the cytoplasm via a myriad of different protein-protein interactions and second messenger cascades. An accumulation of recent evidence, however, now suggests that signal-transduction pathways also play a critical role in the regulation of protein and membrane trafficking. In particular, the analysis of the signalling pathways initiated by receptor tyrosine kinases at the plasma membrane has yielded new insights into the molecular mechanisms of endocytosis. In addition, recent evidence has suggested potential new roles for two previously characterized vesicle coat proteins in a membrane traffic route that is regulated via cell surface receptor signalling.
