Summary: Enables several functions, including flavonoid 3'-monooxygenase activity; heat shock protein binding activity; and oxidoreductase activity, acting on diphenols and related substances as donors. Contributes to oxidoreductase activity. Involved in several processes, including 9-cis-retinoic acid biosynthetic process; hepatocyte differentiation; and xenobiotic metabolic process. Located in mitochondrial inner membrane. Biomarker of end stage renal disease; heart disease; pulmonary hypertension; and renal cell carcinoma. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); diabetes mellitus (multiple); gastrointestinal system cancer (multiple); hematologic cancer (multiple); and lung disease (multiple). Orthologous to human CYP1A1 (cytochrome P450 family 1 subfamily A member 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
