(Medroxyprogesterone, NCI Thesaurus)
Localized to the endoplasmic reticulum (ER), the cytochrome P450 enzyme CYP17 (P450C17 or CYP17A1) exhibits both 17alpha-hydroxylase and 17,20-lyase activities, and plays a key role in the steroidogenic pathway that produces progestins, mineralocorticoids, glucocorticoids, androgens, and estrogens.
(Galeterone, NCI Thesaurus)
The cytochrome P450 enzyme CYP17A1 (P450C17), localized to the endoplasmic reticulum (ER), exhibits both 17alpha-hydroxylase and 17,20-lyase activities, and plays a key role in the steroidogenic pathway that produces steroidal hormones, such as progestins, mineralocorticoids, glucocorticoids, androgens, and estrogens.
