The Na+,K+-ATPase is a transmembrane protein which generates an electrochemical gradient for sodium and potassium ions thanks to the hydrolysis of ATP. This pump exchanges 3Na+ for 2K+ (out) consuming 1ATP. It belongs to the family of P-type ATPase, also known as E1-E2 ATPases, which are phosphorylated on an Aspartateresidue during the transport cycle. It is vital to animal cells, to regulate their volume and to keep their homeostasis. Depending on the cells where the pump is, it allows the formation of a membrane potential or the transport of molecules through the membrane due to the created ionic concentration gradients. These gradients provide energy for other secondary active transports.
