Summary: Enables delayed rectifier potassium channel activity. Involved in several processes, including cellular response to magnesium ion; detection of mechanical stimulus involved in sensory perception; and nervous system development. Located in several cellular components, including axon; cell surface; and perikaryon. Part of voltage-gated potassium channel complex. Is active in axon initial segment. Is expressed in several structures, including adipose tissue; alimentary system; genitourinary system; immune system; and nervous system. Used to study epilepsy; episodic ataxia type 1; and temporal lobe epilepsy. Human ortholog(s) of this gene implicated in episodic ataxia type 1. Orthologous to human KCNA1 (potassium voltage-gated channel subfamily A member 1). [provided by Alliance of Genome Resources, Dec 2024]

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.
