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

Interacts with SIK1 By similarity. Composed of three subunits: alpha (catalytic), beta and gamma.

Subcellular location

Cell membrane; Multi-pass membrane protein. Melanosome By similarity.

Post-translational modification

Phosphorylation on Tyr-10 modulates pumping activity. Phosphorylation of Ser-941 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.

Sequence similarities

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