  • 功能：
    A cytochrome P450 monooxygenase involved in the metabolism of fatty acids. 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. Hydroxylates fatty acids specifically at the omega-1 position displaying the highest catalytic activity for saturated fatty acids. May be involved in the oxidative metabolism of xenobiotics.

    2. Data suggest that combined treatment with non-nutritive sweetener aspartame and insulin in a rat model of juvenile diabetes induces CYP2E1 in neurons of cerebrum and cerebellum without modifying CYP2E1 in liver, while CYP3A2 is induced in cerebrum/cerebellum and in liver. PMID: 25038063
    3. Impaired growth hormone-mediated signaling is observed in ethanol-exposed hepatocytes and is explained by differential effects of alcohol dehydrogenase (ADH)- and cytochrome P450 2E1 (CYP2E1)-mediated ethanol metabolism on the Jak2/STAT5B pathway. PMID: 28864499
    4.
