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; inorganic cation transmembrane transport; and membrane hyperpolarization. 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, Apr 2022]
