Our Abpromise guarantee covers the use of ab33133 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IP Use a concentration of 4 µg/ml. Use 4 µg to immunoprecipate the a 1 subunit from 500 µg rat kidney microsomes.
IHC-Fr 1/5. Use at a concentration of 5 µg/ml to detect the a 1 subunit in frozen sections of rat kidney and brain, which were fixed in 4% paraformaldehyde.


  • 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.
  • Sequence similarities

    Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIC subfamily.
  • Post-translational

    Phosphorylation on Tyr-10 modulates pumping activity.
  • Cellular localization

    Cell membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
