Summary: 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). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in cerebellum adult (RPKM 13.8), cortex adult (RPKM 11.2) and 4 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
