Mechanisms of protein sorting and coat assembly: insights from the clathrin-coated vesicle pathway

Abstract

Clathrin-coated vesicles have provided the best example illustrating how both soluble and membrane proteins are selectively clustered into a transport intermediate for subsequent delivery to another intracellular compartment. Like cytosolic clathrin adaptors, the adaptor-like complex AP-3 binds to specific membranes and selects membrane proteins by interacting with their sorting signals.
