Summary: Enables several functions, including ATP binding activity; P-type sodium:potassium-exchanging transporter activity; and protein heterodimerization activity. Involved in several processes, including cellular response to mechanical stimulus; monoatomic cation transport; and negative regulation of calcium:sodium antiporter activity. Located in several cellular components, including T-tubule; caveola; and intercalated disc. Part of sodium:potassium-exchanging ATPase complex. Biomarker of hyperhomocysteinemia and hypertension. Human ortholog(s) of this gene implicated in alternating hemiplegia of childhood; electroclinical syndrome (multiple); hypertension; and migraine with aura (multiple). Orthologous to human ATP1A2 (ATPase Na+/K+ transporting subunit alpha 2). [provided by Alliance of Genome Resources, Nov 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.
