Previous GeneCards Identifiers for CYP26A1 Gene
This gene 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 endoplasmic reticulum protein acts on retinoids, including all-trans-retinoic acid (RA), with both 4-hydroxylation and 18-hydroxylation activities. This enzyme regulates the cellular level of retinoic acid which is involved in regulation of gene expression in both embryonic and adult tissues. Two alternatively spliced transcript variants of this gene, which encode the distinct isoforms, have been reported. [provided by RefSeq, Jul 2008]
GeneCards Summary for CYP26A1 Gene
CYP26A1 (Cytochrome P450 Family 26 Subfamily A Member 1) is a Protein Coding gene. Diseases associated with CYP26A1 include Acute Promyelocytic Leukemia and Mixed Germ Cell Cancer. Among its related pathways are Metabolism and Cytochrome P450 - arranged by substrate type. Gene Ontology (GO) annotations related to this gene include iron ion binding and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen. An important paralog of this gene is CYP26C1.
UniProtKB/Swiss-Prot for CYP26A1 Gene
Plays a key role in retinoic acid metabolism. Acts on retinoids, including all-trans-retinoic acid (RA) and its stereoisomer 9-cis-RA. Capable of both 4-hydroxylation and 18-hydroxylation. Responsible for generation of several hydroxylated forms of RA, including 4-OH-RA, 4-oxo-RA and 18-OH-RA.
Has also a significant activity in oxidation of tazarotenic acid and may therefore metabolize that xenobiotic in vivo.
Cytochrome P450 (CYP450) enzymes are a diverse group of catalysts that contains 57 members in humans. CYPs are usually membrane-bound and are localized to the inner mitochondrial or endoplasmic reticular membrane. CYPs have oxygenase activity.
