RABBIT ANTI ATP1B1

Rabbit anti Human ATP1B1 antibody recognizes ATP1B1, also known as beta 1-subunit of Na(+),K(+)-ATPase, Na, K-ATPase beta-1 polypeptide or adenosinetriphosphatase.

The protein encoded by ATP1B1 gene belongs to the family of Na+/K+ and H+/K+ ATPase beta chain proteins, and to the subfamily of Na+/K+ -ATPases. Na+/K+ -ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The beta subunit regulates, through assembly of alpha/beta heterodimers, the number of sodium pumps transported to the plasma membrane. The glycoprotein subunit of Na+/K+ -ATPase is encoded by multiple genes. ATP1B1 gene encodes a beta 1 subunit. Alternatively spliced transcript variants encoding different isoforms have been described, but their biological validity is not known (provided by RefSeq, Mar 2010).

Rabbit anti Human ATP1B1 antibody detects a band of 50 kDa. The antibody has been extensively validated for western blotting using tissue and whole cell lysates.
