Na+/K+-ATPase

Patent Pending Na+ /K+ -ATPase (sodium-potassium adenosine triphosphatase, also known as Na+ /K+ pump, sodium-potassium pump, or sodium pump) is an antiporter-like enzyme (EC 3.6.3.9) (an electrogenic transmembrane ATPase) located in the plasma membrane of all animal cells. The Na+ /K+ -ATPase enzyme pumps sodium out of cells, while pumping potassium into cells. It has antiporter-like activity but is not actually an antiporter since both molecules are moving against their concentration gradient.
