May be involved in the metabolism of various pneumotoxicants including naphthalene. Is able to dealkylate ethoxycoumarin, propoxycoumarin, and pentoxyresorufin but possesses no activity toward ethoxyresorufin and only trace dearylation activity toward benzyloxyresorufin. Bioactivates 3-methylindole (3MI) by dehydrogenation to the putative electrophile 3-methylene-indolenine. an organic molecule + O2 + reduced [NADPH--hemoprotein reductase] = an alcohol + H(+) + H2O + oxidized [NADPH--hemoprotein reductase] Expressed in lung. Rarely detected in liver and placenta. Eight non disease-associated alleles are known: CYP2F1*1, CYP2F1*2A, CYP2F1*2B, CYP2F1*3, CYP2F1*4, CYP2F1*5A, CYP2F1*5B and CYP2F1*6. The sequence shown corresponds to allele CYP2F1*1. Belongs to the cytochrome P450 family. CYP2F1 alleles
