  • Function
    Catalyzes the side-chain cleavage reaction of cholesterol to pregnenolone.
  • Pathway
    Lipid metabolism; C21-steroid hormone metabolism.
  • Involvement in disease
    Defects in CYP11A1 are a cause of congenital adrenal insufficiency (CAI).
    Defects in CYP11A1 are a cause of congenital lipoid adrenal hyperplasia (CLAH) [MIM:201710]; also known as 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.

      Developed using the ECL technique.

      Performed under reducing conditions.

      Predicted band size: 60 kDa
      Observed band size: 60 kDa
      Additional bands at: 55 kDa (possible cleavage fragment), 80 kDa, 85 kDa. We are unsure as to the identity of these extra bands.

      Exposure time: 15 minutes

      CYP11A1 protein has a predicted molecular weight of 60-kDa, but contains a 39 amino acid transit protein at the N-terminus. Cleavage of this transit protein would result in a protein with an expected MW of around 55-kDa.
