Summaries for BCO1 Gene

Entrez Gene Summary for BCO1 Gene

  • Vitamin A metabolism is important for vital processes such as vision, embryonic development, cell differentiation, and membrane and skin protection. The protein encoded by this gene is a key enzyme in beta-carotene metabolism to vitamin A. It catalyzes the oxidative cleavage of beta,beta-carotene into two retinal molecules. [provided by RefSeq, Jul 2008]

GeneCards Summary for BCO1 Gene

BCO1 (Beta-Carotene Oxygenase 1) is a Protein Coding gene. Diseases associated with BCO1 include Hypercarotenemia And Vitamin A Deficiency, Autosomal Dominant and Hereditary Hypercarotenemia And Vitamin A Deficiency. Among its related pathways are Metabolism of fat-soluble vitamins and Signaling by GPCR. GO annotations related to this gene include monooxygenase activity and beta-carotene 15,15-monooxygenase activity. An important paralog of this gene is BCO2.
