Identification
HMDB Protein ID CDBP01423
Secondary Accession Numbers Not Available
Name Sodium/potassium-transporting ATPase subunit alpha-2
Description Not Available
Synonyms
  1. Na(+)/K(+) ATPase alpha-2 subunit
  2. Sodium pump subunit alpha-2
Gene Name ATP1A2
Protein Type Enzyme
Biological Properties
General Function Involved in ATP binding
Specific 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, providing the energy for active transport of various nutrients.
