mRNAs from the alpha- and beta-subunits (mRNA alpha and mRNA beta, respectively) of Torpedo californica (Na,K)-ATPase were injected into Xenopus laevis oocytes either separately or in combination, and the properties of the two subunits synthesized were studied. The alpha-subunit synthesized in oocytes injected with mRNA alpha alone was recovered in both the membrane and cytosol fractions and was susceptible to tryptic attack. When mRNA beta was coinjected with mRNA alpha, almost all the alpha-subunit was found in the membrane fraction and was resistant to trypsin. In all cases, essentially all of the beta-subunit was recovered in the membrane fraction and was resistant to trypsin. As the amount of mRNA beta coinjected increased, the amounts of both the alpha- and beta-subunits as well as (Na,K)-ATPase activity of the membrane fraction increased. These results suggest that the beta-subunit facilitates the correct assembly of the alpha-subunit into the membrane probably by forming a stable complex with the nascent alpha-subunit.
