WebDcytb (duodenal cytochrome b) is an iron-regulated ferric reductase highly expressed in duodenal enterocytes. Its location and strong regulation by iron has indicated it plays an important role in iron absorption. Expression of Dcytb in cells (Caco-2 and MDCK) was found to increase both ferric reductase activity and stimulate uptake of (59)Fe.
