CYP2F1 is a member of the Cytochrome P450 enzyme family in humans. CYP2F1 has been detected primarily in the lungs, with only a very weak concentration in the human liver.

The endogenous toxin derived from the fermentation of tryptophan known as 3-methylindole is dehydrogenated into 3-methyleneindolenine by CYP2F1.

CYP2F1 epoxidizes naphthalene to its highly toxic intermediate, naphthalene-

Other known substrates include toluene, propoxycoumarin, pentoxyresoru´Čün, and ethoxycoumarin.
