Abstract A complementary DNA clone encoding the alpha subunit of the adenylate cyclase stimulatory G protein (Gs) was isolated and identified. A bovine brain complementary DNA library was screened with an oligonucleotide probe derived from amino acid sequence common to known G proteins. The only clone that was obtained with this probe has a complementary DNA insert of approximately 1670 base pairs. An antibody to a peptide synthesized according to deduced amino acid sequence reacts specifically with the alpha subunit of Gs. In addition, RNA that hybridizes with probes made from the clone is detected in wild-type S49 cells; however, cyc- S49 cells, which are deficient in Gs alpha activity, are devoid of this messenger RNA.
