Primary structure of the beta-subunit of bovine transducin deduced from the cDNA sequence

FEBS Lett. 1985 Oct 28;191(2):235-40. doi: 10.1016/0014-5793(85)80015-6.


DNA complementary to the bovine retinal mRNA coding for the beta-subunit of transducin has been cloned by screening a cDNA library with oligodeoxyribonucleotide probes. Nucleotide sequence analysis of the cloned cDNA has revealed that this polypeptide consists of 340 amino acid residues (including the initiating methionine). Furthermore, cDNA hybridizable with a transducin beta-subunit cDNA probe has been cloned from a library derived from bovine brain poly(A)+ RNA. Comparison of the cloned cDNAs, in conjunction with blot hybridization analysis and S1 nuclease mapping of poly(A)+ RNA from bovine retina, brain and liver, suggests that the mRNAs coding for the beta-subunits of transducin and other guanine nucleotide binding proteins have the same protein-coding sequence but partly different 5'-noncoding sequences.
