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 By similarity. May contribute to blood-heart barrier properties of endocardial endothelium and may control cardiac performance via endothelial Na+/H+ exchange. Ref.1

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. Interacts with SIK1 By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity.

Tissue specificity

Expressed in endocardial endothelial cells. Ref.1

Post-translational modification

Phosphorylation on Tyr-10 modulates pumping activity. Dephosphorylation by protein phosphatase 2A (PP2A) following increases in intracellular sodium, leading to increase catalytic activity By similarity.

Sequence similarities

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