Gene: ATP4A (ATPase H+/K+ transporting subunit alpha) Homo sapiens
Symbol: ATP4A
Name: ATPase H+/K+ transporting subunit alpha
Description: Predicted to have potassium:proton exchanging ATPase activity and sodium:potassium-exchanging ATPase activity. Predicted to be involved in cellular monovalent inorganic cation homeostasis and inorganic cation transmembrane transport. Localizes to the extracellular space.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ATP6A; ATPase H+/K+ transporting alpha subunit; ATPase, H+/K+ exchanging, alpha polypeptide; ATPase, H+/K+ transporting, alpha polypeptide; gastric H(+)/K(+) ATPase subunit alpha; gastric H+/K+ ATPase alpha subunit; gastric H,K-ATPase alpha subunit; gastric H,K-ATPase catalytic subunit; gastric hydrogen-potassium ATPase; H(+)-K(+)-ATPase alpha subunit; potassium-transporting ATPase alpha chain 1; proton pump
