Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables voltage-gated calcium channel activity involved in regulation of presynaptic cytosolic calcium levels. Involved in regulation of synaptic vesicle exocytosis. Acts upstream of or within several processes, including adult walking behavior; cellular response to leukemia inhibitory factor; and hematopoietic or lymphoid organ development. Part of voltage-gated calcium channel complex. Is active in glutamatergic synapse. Is expressed in brain; heart; and urinary system. Human ortholog(s) of this gene implicated in dilated cardiomyopathy; episodic ataxia; episodic ataxia type 5; and idiopathic generalized epilepsy 9. Orthologous to human CACNB4 (calcium voltage-gated channel auxiliary subunit beta 4).
