voltage-gated calcium channel activity involved in positive regulation of presynaptic cytosolic calcium levels
voltage-gated calcium channel activity involved in positive regulation of presynaptic cytosolic calcium levels
Positive regulation of presynaptic cytosolic calcium ion concentrations via the directed movement of calcium ions across the plasma-membrane into the cytosol via the action of voltage-gated calcium ion channels. This is the first step in synaptic transmission.
