CDNA FOR THE BETA-1 SUBUNIT OF GUANYL NUCLEOTIDE-BINDING REGULATORY PROTEINS FROM MOUSE ADRENAL-GLANDS

cDNA encoding the beta 1 subunit of guanyl nucleotide binding regulato ry proteins was isolated from a mouse adrenal cDNA library. The coding region was 90% identical to human and bovine beta 1 at the cDNA level and 100% identical at the protein level. In the 5' untranslated regio n, two sequence variants were isolated that differed by the presence o r absence of a 49 base pair insert presumed to arise from alternative splicing.
