This gene is a member of the cytochrome b(561) family that encodes an iron-regulated protein. It highly expressed in the duodenal brush border membrane. It has ferric reductase activity and is believed to play a physiological role in dietary iron absorption. [provided by RefSeq, Jul 2008]
GeneCards Summary for CYBRD1 Gene
CYBRD1 (Cytochrome B Reductase 1) is a Protein Coding gene. Diseases associated with CYBRD1 include hemochromatosis and porphyria cutanea tarda. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Insulin receptor recycling. GO annotations related to this gene include ferric-chelate reductase activity and oxidoreductase activity, oxidizing metal ions. An important paralog of this gene is CYB561A3.
UniProtKB/Swiss-Prot for CYBRD1 Gene
Ferric-chelate reductase that reduces Fe(3+) to Fe(2+). Present at the brush border of duodenal enterocytes where it probably reduces dietary Fe(3+) thereby facilitating its transport into the mucosal cells. Uses ascorbate as electron donor. May be involved in extracellular ascorbate recycling in erythrocyte membranes. May also act as a ferrireductase in airway epithelial cells.
