Summary: Enables low voltage-gated calcium channel activity. Involved in calcium ion import and calcium ion transport into cytosol. Acts upstream of or within calcium ion transport and regulation of membrane potential. Predicted to be part of voltage-gated sodium channel complex. Predicted to be active in neuron projection. Biomarker of sciatic neuropathy. Human ortholog(s) of this gene implicated in schizophrenia. Orthologous to human CACNA1I (calcium voltage-gated channel subunit alpha1 I).

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.
