CYP11A1 (cholesterol side-chain cleavage enzyme)

Short target page →

CYP11A1 is the first enzyme in making every steroid hormone from cholesterol; the historic breast cancer drug aminoglutethimide blocked it, cutting oestrogen and adrenal steroids, before aromatase inhibitors made that approach precise. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

A mitochondrial cytochrome P450 of adrenal cortex, gonads and placenta; it requires adrenodoxin and adrenodoxin reductase to receive electrons from NADPH.

Where it is found
  • Adrenal cortex, ovary, testis and placenta
  • Adrenocortical carcinoma and steroid-producing tumours
