Summary of CYP1A2
The CYP1A2 gene encodes cytochrome P450 family 1 subfamily A member 2 [R].
This enzyme is mainly found in the liver, where it helps make cholesterol and steroids. It also breaks down some drugs and toxins, including [R]:
- Caffeine
- Acetaminophen (Tylenol)
- Aflatoxin B1
- Many carcinogens
- Heterocyclic amines (HCAs, from charred meat)
This enzyme can be blocked by some antibiotics, herbs, and herbal teas [R].
This enzyme’s activity can be increased by nicotine and cruciferous vegetables [R].
