Recombinant Human Cytochrome P450 4F12 (CYP4F12), Truncated

Uniprot Id

Q9HCS2

Target Species

Human

Target Name

CYP4F12

Target Full Name

Cytochrome P450 4F12

Target Function

A cytochrome P450 monooxygenase involved in the metabolism of endogenous polyunsaturated fatty acids (PUFAs). 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-ferrihemoprotein reductase). Catalyzes the hydroxylation of carbon hydrogen bonds, with preference for omega-2 position. Metabolizes (5Z,8Z,11Z,14Z)-eicosatetraenoic acid (arachidonate) toward 18-hydroxy arachidonate. Catalyzes the epoxidation of double bonds of PUFAs such as docosapentaenoic and docosahexaenoic acids. Has low omega-hydroxylase activity toward leukotriene B4 and arachidonate. Involved in the metabolism of xenobiotics. Catalyzes the hydroxylation of the antihistamine drug ebastine.

Target Background

This gene 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 likely localizes to the endoplasmic reticulum. When expressed in yeast the enzyme is capable of oxdizing arachidonic acid. It can also catalyze the epoxidation of 22:6n-3 and 22:5n-3 polyunsaturated long-chain fatty acids. This gene is part of a cluster of cytochrome P450 genes on chromosome 19. Alternative splicing results in multiple transcript variants.
