研究背景

功能:

A cytochrome P450 monooxygenase involved in the metabolism of various endogenous substrates, including fatty acids, steroid hormones and vitamins. 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 hydroxylation of carbon-hydrogen bonds. Exhibits high catalytic activity for the formation of hydroxyestrogens from estrone (E1) and 17beta-estradiol (E2), namely 2-hydroxy E1 and E2, as well as D-ring hydroxylated E1 and E2 at the C15-alpha and C16-alpha positions. Displays different regioselectivities for polyunsaturated fatty acids (PUFA) hydroxylation. Catalyzes the epoxidation of double bonds of certain PUFA. Converts arachidonic acid toward epoxyeicosatrienoic acid (EET) regioisomers, 8,9-, 11,12-, and 14,15-EET, that function as lipid mediators in the vascular system. Displays an absolute stereoselectivity in the epoxidation of eicosapentaenoic acid (EPA) producing the 17(R),18(S) enantiomer. May play an important role in all-trans retinoic acid biosynthesis in extrahepatic tissues. Catalyzes two successive oxidative transformation of all-trans retinol to all-trans retinal and then to the active form all-trans retinoic acid. May also participate in eicosanoids metabolism by converting hydroperoxide species into oxo metabolites (lipoxygenase-like reaction, NADPH-independent).

亚基结构:

Interacts with cytosolic chaperones HSP70 and HSP90; this interaction is required for initial targeting to mitochondria. Interacts (via mitochondrial targeting signal) with TOMM40 (via N-terminus); this interaction is required for translocation across the mitochondrial outer membrane.

蛋白家族:

Belongs to the cytochrome P450 family.

Metabolizes cholesterol toward 25-hydroxycholesterol, a physiological regulator of cellular cholesterol homeostasis. May act as a major enzyme for all-trans retinoic acid biosynthesis in the liver. Catalyzes two successive oxidative transformation of all-trans retinol to all-trans retinal and then to the active form all-trans retinoic acid. Primarily catalyzes stereoselective epoxidation of the last double bond of polyunsaturated fatty acids (PUFA), displaying a strong preference for the (R,S) stereoisomer. Catalyzes bisallylic hydroxylation and omega-1 hydroxylation of PUFA. May also participate in eicosanoids metabolism by converting hydroperoxide species into oxo metabolites (lipoxygenase-like reaction, NADPH-independent). Plays a role in the oxidative metabolism of xenobiotics. Catalyzes the N-hydroxylation of heterocyclic amines and the O-deethylation of phenacetin. Metabolizes caffeine via N3-demethylation (Probable).

Application: WB    Species: Rat    Sample: intestine, kidney, and liver tissue

Fig. 2 AOPPs downregulated the protein expression and activities of CYP1A2 and CYP3A4 in vivo. Total protein was extracted from the intestine, kidney, and liver in the sham (A) and 5/6 nx groups (B), and the protein expression of CYP1A2 and CYP3A4 in a whole-cell lysate was evaluated by western blotting. Proteins expression levels were quantified by ImageJ software (C, D). Each experiment was performed with a different isolate. Michaelis–Menten plots of acetaminophen (E) and 6β-hydroxytestosterone (F) were constructed after incubation of liver microsomes (extracted from the liver tissues in the sham and 5/6 nx groups) with NADPH and various concentrations of phenacetin or testosterone, respectively, which were used to evaluate the activities of CYP1A2 and CYP3A4, respectively. Each data point represents the mean of three replicates and the error bars represent standard error of the mean (n = 3). Data are presented as mean ± SD; *p < 0.05 compared with the PBS group. Data were normalized to GAPDH.

Fig. 6| AOPPs downregulated CYP1A2 and CYP3A4 expression via the NF-κBpathway. NF-κB-dependent firefly luciferase reporter gene was transfected into HepG2 or L-02 cells, and the reporter gene expression (A). HepG2 or L-02 cells were treated with AOPPs (200 µg/ml) for 48 h and cocultured with BAY-117082 (B) and PDTC (C) to restore the downregulated expression levels of CYP1A2 and CYP3A4.
