Target Background

(From Uniprot)
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.

  4. Herein potential interaction between NTS1 receptor, dopaminergic D2 receptor and Na(+), K(+)-ATPase was studied.Results indicated that typical and atypical antipsychotic drugs differentially modulate the interaction between neurotensin and Na(+), K(+)-ATPase. PMID: 27586561

  21. Data indicate that exposure to cobalt (Co) decreased Na(+)K(+)-ATPase activity in the cerebrum and cerebellum of suckling pups. PMID: 23857379
