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. 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] |
