Comments
  • FUNCTION: Catalyzes the side-chain cleavage reaction of cholesterol to pregnenolone.
  • CATALYTIC ACTIVITY: Cholesterol + reduced adrenal ferredoxin + O2 = pregnenolone + 4-methylpentanal + oxidized adrenal ferredoxin + H2O.
  • COFACTOR: Heme group (By similarity).
  • PATHWAY: Lipid metabolism; C21-steroid hormone metabolism.
  • SUBCELLULAR LOCATION: Mitochondrion membrane.
  • INDUCTION: By 8-bromo cyclic AMP.
  • DISEASE: Defects in CYP11A1 are a cause of congenital adrenal insufficiency (CAI).
  • DISEASE: Defects in CYP11A1 are a cause of congenital lipoid adrenal hyperplasia (CLAH) [MIM:201710]; also called lipoid CAH. CLAH is the most severe form of adrenal hyperplasia. This autosomal recessive and potentially lethal condition includes the onset of profound adrenocortical insufficiency shortly after birth, hyperpigmentation reflecting increased production of pro-opiomelanocortin, elevated plasma renin activity as a consequence of reduced aldosterone synthesis, and male pseudohermaphroditism resulting from deficient fetal testicular testosterone synthesis. CLAH is a rare disease, except in Japan and Korea where it accounts for a significant percentage of cases of congenital adrenal hyperplasia.
  • SIMILARITY: Belongs to the cytochrome P450 family.
