title: Molecular cloning of DNA complementary to bovine adrenal P450scc mRNA.
abstract: P450scc is the rate-limiting hormonally regulated enzyme that cleaves the cholesterol side chain. Translation of bovine adrenocortical mRNA and immunoprecipitation with rabbit anti-bovine P450scc indicates P450scc mRNA represents 1% of the total. DNA complementary to bovine adrenocortical mRNA was cloned in the PstI site of pBR322 by dC X dG tailing and high-efficiency transformation. A clone containing sequences complementary to P450scc mRNA was identified by hybrid-selected translation only when plasmid DNA was first purified by CsCl gradient centrifugation. As is often the case with hybrid-selected translation, the clone identified contains a small insert.
