Primary structure of the α‐subunit of bovine adenylate cyclase‐stimulating G‐protein deduced from the cDNA sequence

Abstract
The primary structure of the α‐subunit of the adenylate cyclase‐stimulating G‐protein (Gs) has been deduced from the nucleotide sequence of cloned DNA complementary to the bovine cerebral mRNA encoding the polypeptide. Comparison of the amino acid sequences of the α‐subunits of Gs and transducin reveals that some of the highly conserved regions show sequence homology with elongation factor‐Tu and ras p21 proteins and correspond to functional regions of guanine nucleotide‐binding proteins.
