Abstract:
The cDNA encoding the third type of alpha-subunit of NaK-ATPase was found in rat brain cDNA library. The deduced amino acid sequence was very similar to those of alpha- and alpha plus-subunits. The third one was suggested to be highly ouabain-sensitive from its aminoacid sequence. From Northern blot analysis the third type of the subunit was not expressed in adult rat kidney and heart.
