A. The subunits of calcium channels. B. Transmembrane folding diagrams of the calcium channel subunits. C. The presynaptic Ca2+ channel signaling complex. Sites of interaction of SNARE proteins (the synprint site), Gβγ subunits, protein kinase C (PKC), calmodulin and neuronal Ca2+ binding proteins (CBD), and Ca2+/calmodulin-dependent protein kinase II are illustrated.
