label_lc: voltage-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential
description: "Voltage-gated ion channel activity, occurring in the presynaptic membrane, involved in regulation of presynaptic membrane potential. This is a key step in synaptic transmission, following the arrival of an action potential at the synapse."
