We have developed a panel of antibodies specific for the alpha 1, alpha 2, alpha 3, and beta subunits of the rat Na,K-ATPase. TrpE-alpha subunit isoform fusion proteins were used to generate three antisera, each of which reacted specifically with a distinct alpha subunit isotype. Western blot analysis of rat tissue microsomes revealed that alpha 1 subunits were expressed in all tissues while alpha 2 subunits were expressed in brain, heart, and lung. The alpha 3 subunit, a protein whose existence had been inferred from cDNA cloning, was expressed primarily in brain and copurified with ouabain-inhibitable Na,K-ATPase activity. An antiserum specific for the rat Na,K-ATPase beta subunit was generated from a TrpE-beta subunit fusion protein. Western blot analysis showed that beta subunits were present in kidney, brain, and heart. However, no beta subunits were detected in liver, lung, spleen, thymus, or lactating mammary gland. The distinct tissue distributions of alpha and beta subunits suggest that different members of the Na,K-ATPase family may have specialized functions.
