Summary: Enables several functions, including adenyl ribonucleotide binding activity; alkali metal ion binding activity; and ankyrin binding activity. Involved in several processes, including cellular response to mechanical stimulus; membrane hyperpolarization; and monoatomic cation transmembrane transport. Located in several cellular components, including T-tubule; basolateral plasma membrane; and intercalated disc. Part of sodium:potassium-exchanging ATPase complex. Used to study hypertension. Biomarker of hyperhomocysteinemia and sensorineural hearing loss. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease type 2DD. Orthologous to human ATP1A1 (ATPase Na+/K+ transporting subunit alpha 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.
