General annotation (Comments)

Function

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.

Catalytic activity

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

Subunit structure

Composed of three subunits: alpha (catalytic), beta and gamma.

Subcellular location

Cell membrane; Multi-pass membrane protein.

Sequence similarities

Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIC subfamily. [View classification]
