Protein

Sodium/potassium-transporting ATPase subunit alpha-1

Gene

ATP1A1

Organism
Oryctolagus cuniculus (Rabbit)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

This is the catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of sodium and potassium ions across the plasma membrane. This action creates the electrochemical gradient of sodium and potassium ions, providing the energy for active transport of various nutrients (By similarity). May contribute to blood-heart barrier properties of endocardial endothelium and may control cardiac performance via endothelial Na+/H+ exchange.By similarity1 Publication

Catalytic activityi

ATP + H2O + Na+(In) + K+(Out) = ADP + phosphate + Na+(Out) + K+(In).

Post-translational modificationi

Phosphorylation on Tyr-10 modulates pumping activity. Phosphorylation of Ser-943 by PKA modulates the response of ATP1A1 to PKC. Dephosphorylation by protein phosphatase 2A (PP2A) following increases in intracellular sodium, leading to increase catalytic activity (By similarity).By similarity
