Protein

Sodium/potassium-transporting ATPase subunit alpha-4

Gene

Atp1a4

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript 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. Plays a role in sperm motility.1 Publication

Catalytic activityi

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

Enzyme regulationi

Specifically inhibited by an endogenous cardiac glycoside, ouabain.By similarity
