17-Alpha-Hydroxylase (S17aH)

CYP17A1; CPT7; P450C17; 17-alpha-hydroxyprogesterone aldolase/17,20-Lyase; Steroid 17-alpha-monooxygenase; Cytochrome P450,Family 17,Subfamily A,Polypeptide 1

  • CYP17A1 (also known as 17 alpha-hydroxylase/17,20 lyase/17,20 desmolase) is a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids.

  • This protein localizes to the endoplasmic reticulum. It has both 17alpha-hydroxylase and 17,20-lyase activities and is a key enzyme in the steroidogenic pathway that produces progestins, mineralocorticoids, glucocorticoids, androgens, and estrogens. Mutations in this gene are associated with isolated steroid-17 alpha-hydroxylase deficiency, 17-alpha-hydroxylase/17,20-lyase deficiency, pseudohermaphroditism, and adrenal hyperplasia.
