I'm learning the basics of cell biology and one thing about the SNAP-SNARE complex is confusing me a lot.
I read that the SNAP-SNARE complex has nothing to do with endocytosis. But my question is: endocytosis and exocytosis both ultimately lead to the formation of a vesicle; and a vesicle, once formed, must fuse with a target membrane. The SNAP-SNARE complex mediates fusion of vesicles with target membranes, so wouldn't that mean that it controls the fusion of both endocytic and exocytic vesicles with their respective target membranes?
Am I making a gigantic blunder here? It would be great if someone could clarify this.
