Conversion of cholesterol to pregnenolone is mediated by P450scc [cholesterol, reduced-adrenal-ferrodoxin: oxygen oxidoreductase (side-chain-cleaving), EC 1.14.15.67]. RNA from several human adrenal samples was translated in vitro and immunoprecipitated with anti-bovine P450scc, indicating that P450scc mRNA represents about 0.5% of human adrenal mRNA in normal, hypertrophied, and malignant adrenals. A 1626-base-pair human adrenal P450scc cDNA was cloned in bacteriophage lambda gt10. Primer extension data indicated P450scc mRNA is about 1850 bases long and that all adrenal P450scc mRNA has the same 5' end. A full-length clone containing 1821 bases was obtained from a human testis cDNA library to yield the complete sequence. The encoded human preP450scc contains 521 amino acids with a molecular weight of 60189.65. The testis and adrenal sequences were identical; the human cDNA and amino acid sequences are 82% and 72% homologous, respectively, with the bovine sequences. P450scc cDNA was used to probe DNA from a panel of mouse-human somatic cell hybrids, showing that the single human P450scc gene lies on chromosome 15. The human P450scc gene is expressed in the placenta in early and midgestation; primary cultures of placental tissue indicate P450scc mRNA accumulates in response to cyclic AMP.
