Summary: Enables high voltage-gated calcium channel activity; protein phosphatase 2A binding activity; and voltage-gated calcium channel activity involved in regulation of presynaptic cytosolic calcium levels. Involved in several processes, including calcium ion import; regulation of calcium-dependent activation of synaptic vesicle fusion; and response to testosterone. Located in axon terminus; dendritic shaft; and neuronal cell body. Part of protein-containing complex. Is active in Schaffer collateral - CA1 synapse and glutamatergic synapse. Human ortholog(s) of this gene implicated in Lambert-Eaton myasthenic syndrome. Orthologous to human CACNA1B (calcium voltage-gated channel subunit alpha1 B).

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.
