Function
This enzyme catalyzes the hydroxylation (with S stereochemistry) at C-24 of cholesterol side chain, triggering cholesterol diffusion out of neurons and its further degradation. It further hydroxylates cholesterol derivatives and hormone steroids on both the ring and side chain of these molecules, converting them into active oxysterols involved in lipid signaling and biosynthesis. It acts as an epoxidase converting cholesta-5,24-dien-3beta-ol/desmosterol into (24S),25-epoxycholesterol, Besides, it may also catalyze the oxidative metabolism of xenobiotics, such as clotrimazole.
KEGG Pathway
Primary bile acid biosynthesis (hsa00120 )
Reactome Pathway
Synthesis of bile acids and bile salts via 24-hydroxycholesterol (R-HSA-193775 )
Endogenous sterols (R-HSA-211976 )
