CYP1A1 - cytochrome P450 family 1 subfamily A member 1 Gene
Also Known as AHH; AHRR; CP11; CYP1; CYPIA1; P1-450; P450-C; P450DX
Species: Homo sapiens
About CYP1A1
This gene has 9 transcripts (splice variants), 252 orthologues and 2 paralogues. Biased expression in urinary bladder (RPKM 40.8), liver (RPKM 18.0) and 1 other tissue.
Summary
This gene, CYP1A1, 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. This protein localizes to the endoplasmic reticulum and its expression is induced by some polycyclic aromatic hydrocarbons (PAHs), some of which are found in cigarette smoke. The enzyme's endogenous substrate is unknown; however, it is able to metabolize some PAHs to carcinogenic intermediates. The gene has been associated with lung Cancer risk. A related family member, CYP1A2, is located approximately 25 kb away from CYP1A1 on chromosome 15. Alternative splicing results in multiple transcript variants encoding distinct isoforms.
