We have isolated cDNA clones for the rat stomach (H+ + K+)-ATPase by employing a novel procedure involving the use of oligonucleotides corresponding to conserved amino acid sequences of related cation transport ATPase and a cross-hybridization with the sheep kidney (Na+ + K+)-ATPase alpha-subunit cDNA. The complete nucleotide sequence of the cDNA has been determined and the amino acid sequence of the protein deduced. The ATPase consists of 1,033 amino acids and has an Mr of 114,012. Amino acid homology and hydropathy plot comparisons between the gastric ATPase and the (Na+ + K+)-ATPase catalytic subunit demonstrate a striking similarity which suggests that their higher order structure and mechanism of action are virtually identical. The greatest homology occurs in the phosphorylation site region and in domains which may be involved in nucleotide binding and energy transduction. The most substantial differences occur in the N-terminal region and in the transmembrane domains. In addition, we report the presence of an open reading frame 5' to the translation initiation site of the gastric ATPase, which raises the possibility that the mRNA is polycistronic.
