Cytochrome P450 1A1 (CYP1A1)

Target
CYP1A1
Molecular classification
Enzyme, Cytochrome P450, Monooxygenase
01

Overview

CYP1A1 is an extrahepatic cytochrome P450 monooxygenase crucial for both detoxifying harmful compounds and activating certain procarcinogens. Its dual role makes it significant both physiologically—for normal metabolic processing—and pathologically—in cancer risk associated with environmental exposures. Its expression is tightly regulated by environmental factors through AhR signaling pathways.
