Endocytosis refers to the recovery of vesicles from the plasma membrane. Exocytotic vesicle fusion involves the coalescence of vesicle and plasma membranes and allows the so-called fusion pore to form. The fusion pore is a channel that passes through the vesicle and plasma membranes and allows delivery of the vesicle contents to the extracellular compartment. Docking is the pro-cess by which the exocytotic vesicle is fixed beneath the plasma membrane before fusion. It is generally
