Protein
Sodium/potassium-transporting ATPase subunit alpha
Organism
Drosophila melanogaster
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.
Similarity
Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIC subfamily.
