Also known as: CP12; CYPIA2; P450-3
Summary: Enables oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen. Acts upstream of or within several processes, including cellular response to cadmium ion; dibenzo-p-dioxin metabolic process; and hydrogen peroxide biosynthetic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in intracellular membrane-bounded organelle. Is expressed in liver. Human ortholog(s) of this gene implicated in breast cancer; chronic obstructive pulmonary disease; endometrial cancer; and porphyria cutanea tarda. Orthologous to human CYP1A2 (cytochrome P450 family 1 subfamily A member 2). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
