Automated description from the Alliance of Genome Resources (Release 7.4.0)

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).
