The length of time that integral membrane proteins reside on the plasma membrane is regulated by endocytosis, a process that can inactivate these proteins by removing them from the membrane and may ultimately result in their degradation. Proteins are internalized and pass through multiple distinct intracellular compartments where targeting decisions determine their fate. Membrane proteins initially enter early endosomes, and subsequently late endosomes/multivesicular bodies (MVBs), before being degraded in the lysosome. The MVB is a subset of late endosomes characterized by the appearance of small vesicles in its luminal compartment. These vesicles contain cargo proteins sorted from the limiting ...
