RIM and RIM-binding protein localize synaptic CaV2 channels to differentially regulate transmission in neuronal circuits

Abstract At chemical synapses, voltage-gated Ca2+-channels (VGCCs) translate electrical signals into a trigger for synaptic vesicle (SV) fusion. VGCCs and the Ca2+ microdomains they elicit must be located precisely to primed SVs, to evoke rapid transmitter release. Localization is mediated by Rab3 interacting molecule (RIM) and RIM-binding proteins (RIM-BPs), which interact and bind to the C-terminus of the CaV2 VGCC α-subunit.
