CYP27A1 is a gene encoding a cytochrome P450 oxidase, and is commonly known as sterol 27-hydroxylase. This enzyme is located in many different tissues where it is found within the mitochondria. It is most prominently involved in the biosynthesis of bile acids.

Mar 30, 2025 · CYP27A1 (Cytochrome P450 Family 27 Subfamily A Member 1) is a Protein Coding gene. Diseases associated with CYP27A1 include Cerebrotendinous Xanthomatosis and Xanthomatosis. Among its related pathways are Bile acid and bile salt metabolism and Oxidation by cytochrome P450.

The CYP27A1 gene provides instructions for producing an enzyme called sterol 27-hydroxylase. This enzyme is located in the energy-producing centers of cells (mitochondria), where it is involved in the pathway that breaks down cholesterol to form acids used to digest fats (bile acids).

The CYP27A gene encodes a mitochondrial cytochrome P450 enzyme, sterol 27-hydroxylase, that is expressed in many different tissues and plays an important role in cholesterol and bile acid metabolism. In humans, CYP27A deficiency leads to cerebrotendinous xanthomatosis.

CYP27A1 is a critical cellular cholesterol sensor in prostate cells and that dysregulation of the CYP27A1/27-hydroxycholesterol (27HC) axis contributes significantly to prostate cancer pathogenesis. CYP27A1 catalyzes hydroxylation of beta-sitosterol and ergosterol

Mitochondrial sterol 27-hydroxylase (CYP27A1) catalyzes oxidative cleavage of the sterol side chain in the bile acid biosynthetic pathway in the liver and 27-hydroxylation of cholesterol in most tissues.

Aug 14, 2003 · Mitochondrial sterol 27-hydroxylase (CYP27A1) catalyses sterol side-chain oxidation of bile acid synthesis from cholesterol, and the first reaction of the acidic bile acid biosynthetic pathway. Hydrophobic bile acids suppress human CYP27A1 gene reporter activity when assayed in human hepatocellular blastoma HepG2 cells.

CYP27A1 is a liver mitochondrial CYP with a homolog in >190 species, that is 531 amino acids in size in the human, and was originally cloned from rabbit but also from human [33,34].

Feb 8, 2025 · High expression of cytochrome P450 family 27 subfamily A member 1 (CYP27A1), the enzyme responsible for the synthesis of 27-Hydroxycholesterol (27HC), is associated with decreased progression free survival for ovarian cancer.

Jan 14, 2021 · FUNCTION: Catalyzes the first step in the oxidation of the side chain of sterol intermediates; the 27-hydroxylation of 5-beta- cholestane-3-alpha,7-alpha,12-alpha-triol. Has also a vitamin D3- 25-hydroxylase activity. COFACTOR: Heme group. PATHWAY: Hormone biosynthesis; cholecalciferol biosynthesis. SUBCELLULAR …
