CYP2E1
cytochrome P450 family 2 subfamily E member 1
Pathway candidate — not linked to PFS or PSSD by any record here
Gene summary
A protein-coding gene on chromosome 10 (drug metabolism (phase i)). 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.

Protein reference (UniProt)
- Protein
Cytochrome P450 2E1
- Function
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 (Probable).
- Pathway
Lipid metabolism; fatty acid metabolism.
- Subcellular location
Endoplasmic reticulum membrane; Microsome membrane; Mitochondrion inner membrane.

Why its pathway is in the library
Phase I enzymes determine exposure to finasteride, SSRIs, and other implicated drugs; variation here shapes the likelihood and persistence of adverse effects.
Written for the whole drug metabolism family, not for CYP2E1 specifically.
Mentioned in 0 corpus records
No corpus record names CYP2E1 directly yet. It is in the library because it sits in a pathway the corpus tracks (Drug metabolism).
