    Summary
    Predicted to enable low voltage-gated calcium channel activity and voltage-gated sodium channel activity. Acts upstream of or within neuronal action potential and sleep. Predicted to be part of voltage-gated sodium channel complex. Predicted to be active in neuron projection. Is expressed in brain. Human ortholog(s) of this gene implicated in schizophrenia. Orthologous to human CACNA1I (calcium voltage-gated channel subunit alpha1 I). [provided by Alliance of Genome Resources, Apr 2022]

    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.
