General description
7α,27-dihydroxy-4-cholesten-3-one synthesized by the hydroxylation of 27-hydroxycholesterol in the presence of the enzyme cholesterol 7 α-hydroxylase (CYP7A1) and is catabolized to bile acid. 7α,27-dihydroxy-4-cholesten-3-one is present majorly in fibroblasts and its conversion from cholesterol occurs in extrahepatic tissues.
Application
7α,27-dihydroxy-4-cholesten-3-one may be used as a ligand to test its effect on Epstein-Barr virus-induced molecule 2 (EB12) activation in guanosine 5′-O-(3-thio)triphosphate ([35S] GTPγS) binding assay.
Biochem/physiol Actions
7α,27-dihydroxy-4-cholesten-3-one is a suppressor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase.

The mitochondrial sterol 27-hydroxylase (CYP27A1) is required for degradation of the C27-sterol side chain in bile acid biosynthesis. CYP27A1 seems, however, to have roles beyond this, as illustrated by patients with a deficient sterol 27-hydroxylase due to mutations of the
