MA3-930 detects sodium/potassium ATPase beta 1 from mouse, human, sheep, canine, and pig tissues. This antibody does not recognize the beta 1 or beta 2 subunit in rat.
MA3-930 has been successfully used in Western blot and immunohistochemistry and immunocytochemistry procedures. By Western blot, this antibody detects an ~42 kDa protein in liver samples and ~55 kDa in kidney samples representing beta sodium/potassium ATPase in sheep liver extract. Immunohistochemical staining of the sodium/potassium ATPase with MA3-930 yields a pattern consistent with plasma membrane localization.
The MA3-930 antigen is purified lamb kidney sodium/potassium ATPase beta. This antibody recognizes and epitope between amino acid residues 195-199 of sheep sodium/potassium ATPase beta 1.
The protein encoded by this gene belongs to the family of Na+/K+ and H+/K+ ATPases 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. This gene encodes a beta 1 subunit. Alternatively spliced transcript variants encoding different isoforms have been described, but their biological validity is not known.
