Sodium Potassium ATPase Alpha 2 Products

Description

The ubiquitously expressed sodium/potassium-ATPase exists as a oligomeric plasma membrane complex that couples the hydrolysis of one molecule of ATP to the importation of three Na+ ions and two K+ ions against their respective electrochemical gradients. As a member of the P-type family of ion motifs, sodium/potassium-ATPase plays a critical role in maintaining cellular volume, resting membrane potential and Na+-coupled solute transport. Multiple isoforms of three subunits, alpha, beta and gamma, comprise to form the sodium/potassium-ATPase oligomer. The 113 kDa alpha subunit contains the binding sites for ATP and the cations. With a molecular weight between 40 and 60 kDa, the glycosylated beta subunit ensures correct folding and membrane insertion of the alpha subunits. The small 6 kDa gamma subunit co-localizes with the alpha subunit in nephron segments, where it increases the affinity of sodium/potassium-ATPase for ATP. The beta subunit, but not the gamma subunit, is essential for normal activity of sodium/potassium-ATPase.
