Enables voltage-gated calcium channel activity involved in regulation of presynaptic cytosolic calcium levels. Involved in calcium ion import. Located in perikaryon. Part of voltage-gated calcium channel complex. Is active in GABA-ergic synapse. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 69. Orthologous to human CACNA1E (calcium voltage-gated channel subunit alpha1 E). [provided by Alliance of Genome Resources, Apr 2022]
