Molecular anatomy of the presynaptic active zone. Three distinct complexes help to define the active zone (described in text). The first complex is largely structural, and is thought to hold the active zone in register with the postsynaptic density (PSD) and clusters calcium channels within the active plasma membrane. The second complex is involved in synaptic vesicle docking and fusion. The third complex is involved in synaptic vesicle endocytosis. (From (Qui, 2004), with permission).
