Abstract

The α1 subunits of the voltage-gated Ca²⁺-channels α1S, α1C, α1D, and α1F in channels of the Ca_V1.1–1.4 type; α1A in a channel of Ca_V2.1 type; α1E in a channel of Ca_V2.3 type; and α1G, α1H, and α1I in a channel of Ca_V3.1–3.3 type, as well as the synaptic vesicle exo-endocytotic protein synaptophysin, were identified using fluorescence and confocal microscopy in the somatic muscle of the earthworm Lumbricus terrestris. The presynaptic membrane of cholinergic synapses contains voltage-gated Ca²⁺-channels of Ca_V1.1 and Ca_V1.2 (including α1S and α1C subunits), Ca_V2.1 (with α1A subunit), Ca_V2.3 (with α1E subunit), and Ca_V3.2 and Ca_V3.3 (with subunits α1H, α1I) types, while Ca_V1.3 and Ca_V1.4 Ca2⁺-channels with subunits α1D and α1F and Ca_V3.1 channels with subunit α1G are predominantly parts of the muscle membranes.
