P20813 CP2B6_HUMAN:

Expressed in liver, lung and heart right ventricle.

This gene, CYP2B6, encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and its expression is induced by phenobarbital. The enzyme is known to metabolize some xenobiotics, such as the anti-cancer drugs cyclophosphamide and ifosphamide. Transcript variants for this gene have been described; however, it has not been resolved whether these transcripts are in fact produced by this gene or by a closely related pseudogene, CYP2B7. Both the gene and the pseudogene are located in the middle of a CYP2A pseudogene found in a large cluster of cytochrome P450 genes from the CYP2A, CYP2B and CYP2F subfamilies on chromosome 19q.

Research Backgrounds


A cytochrome P450 monooxygenase involved in the metabolism of endocannabinoids and steroids. 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 (NADPH--hemoprotein reductase). Catalyzes the epoxidation of double bonds of arachidonoylethanolamide (anandamide) to 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling. Hydroxylates steroid hormones, including testosterone at C-16 and estrogens at C-2. Plays a role in the oxidative metabolism of xenobiotics, including plant lipids and drugs. Acts as a 1,4-cineole 2-exo-monooxygenase.

Allele 2B6*9: Has low affinity for anandamide and can only produce 11,12 EpETrE-EAs.


Phosphorylation is accompanied by a decrease in enzyme activity.

Application: WB    Species: human    Sample: HepG2 cells

Fig.2| Effect of PXT on CYP2B6 mRNA and protein expression in HepG2 cells.The effect of PXT on CYP2B6 mRNA and protein in HepG2 cells at a series of concentrations (5, 10, 20, 40, and 80 μM) for 24h was determined by real-time Q-PCR analysis (A) and Western blot analysis (B-C). The determination of mRNA and protein was normalized to GAPDH and β-actin, respectively. CITCO (10 μM) and 0.1% DMSO were used as the positive and negative controls, respectively. Results are presented as fold induction relative to control, and all data are expressed mean ± SD of triplicate independent experiments.
