Target Background

A cytochrome P450 monooxygenase involved in primary bile acid biosynthesis. Catalyzes the 12alpha-hydroxylation of 7alpha-hydroxy-4-cholesten-3-one, an intermediate metabolite in cholic acid biosynthesis. Controls biliary balance of cholic acid and chenodeoxycholic acid, ultimately regulating the intestinal absorption of dietary lipids. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH--hemoprotein reductase).
Gene References into Functions
  1. RORalpha is a key regulator of diurnal rhythm and fasting induction of CYP8B1, which regulates bile acid composition and serum and liver cholesterol levels. PMID: 24226095
  2. The single nucleotide polymorphism rs3732860 in the 3'-untranslated region of the CYP8B1 gene is associated with risk of Gallstone Disease in Chinese Han. PMID: 23216301
  3. SNP rs3732860 of CYP8B1 gene is associated with gallstone disease in this Chinese population. PMID: 22093981
  4. Cholesterol loading reduces SREBP-1 mRNA expression in addition to reducing functional SREBP-1 protein, and results in decreasing CYP8B1 gene transcription. PMID: 15249218
  5. Studies indicate a homogenous pattern for CYP8B1 expression in human liver, which was even rather than zonal. PMID: 15891895
  6. Isoflavone-related induction of 12-alpha-hydroxylase (CYP8B1) was studied in vitro and murine in vivo models. PMID: 17585019
