This gene encodes an enzyme which oxidizes carotenoids such as beta-carotene during the biosynthesis of vitamin A. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]
BCO2 (Beta-Carotene Oxygenase 2) is a Protein Coding gene. Diseases associated with BCO2 include Chromosome 13Q14 Deletion Syndrome. Among its related pathways are Signaling by GPCR and Drug metabolism - cytochrome P450. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity, acting on single donors with incorporation of molecular oxygen, incorporation of two atoms of oxygen. An important paralog of this gene is RPE65.
