    Summary
    Enables voltage-gated potassium channel activity. Involved in potassium ion transmembrane transport; regulation of circadian sleep/wake cycle, non-REM sleep; and regulation of dopamine secretion. Acts upstream of or within optic nerve structural organization. Located in several cellular components, including axon; neuronal cell body membrane; and perikaryon. Part of voltage-gated potassium channel complex. Is active in axon initial segment. Is expressed in several structures, including brain; heart ventricle; and hindlimb muscle. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 32. Orthologous to human KCNA2 (potassium voltage-gated channel subfamily A member 2).

    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.
