Automated description from the Alliance of Genome Resources (Release 3.2)
Exhibits heparan sulfate proteoglycan binding activity and sodium:potassium-exchanging ATPase activity involved in regulation of cardiac muscle cell membrane potential. Involved in several processes, including cellular sodium ion homeostasis; learning or memory; and sodium ion export across plasma membrane. Localizes to several cellular components, including photoreceptor inner segment; sarcolemma; and sodium:potassium-exchanging ATPase complex. Is expressed in several structures, including alimentary system; early conceptus; gonad; heart; and nervous system. Used to study alternating hemiplegia of childhood and bipolar disorder. Human ortholog(s) of this gene implicated in alternating hemiplegia of childhood; bipolar disorder; dystonia 12; and epilepsy. Orthologous to human ATP1A3 (ATPase Na+/K+ transporting subunit alpha 3).
