摘要：

At the presynaptic active zone, voltage-gated Ca2+ channels (CaVs) mediate Ca2+ entry for neurotransmitter release. CaVs are a large family of proteins, and different subtypes have distinct localizations across neuronal somata, dendrites and axons. Here, we review how neurons establish and maintain a specific CaV repertoire at their active zones. We focus on molecular determinants for cargo assembly, presynaptic delivery and release site tethering, and we discuss recent work that has identified key roles of the CaV intracellular C-terminus. Finally, we evaluate how these mechanisms may differ between different types of neurons. Work on CaVs provides insight into the protein targeting pathways that help maintain neuronal polarity.
