Ferritins are iron storage proteins that overcome the problems of toxicity and poor bioavailability of iron by catalyzing iron oxidation and mineralization through the activity of a diiron ferroxidase site. Unlike in other ferritins, the oxidized di-Fe3+ site of Escherichia coli bacterioferritin (EcBFR) is stable and therefore does not function as a conduit for the transfer of Fe3+ into the sto...
CNS injury-induced hemorrhage and tissue damage leads to excess iron, which can cause secondary degeneration. The mechanisms that handle this excess iron are not fully understood. We report that spinal cord contusion injury (SCI) in mice induces an "iron homeostatic response" that partially limits iron-catalyzed oxidative damage. We show that ceruloplasmin (Cp), a ferroxidase that oxidizes toxi...
BACKGROUND Hephaestin is a multicopper ferroxidase required for basolateral transport of iron from enterocytes. Sex linked anaemia (sla) mice have a defect in the release of iron from intestinal enterocytes into the circulation due to an interstitial deletion in the hephaestin gene (heph). RESULTS We have demonstrated that hephaestin is primarily localised to a supranuclear compartment in bot...

FOX1 gene encoding a multicopper ferroxidase is vital in iron metabolism in the single-celled green algae Chlamydomonas reinhardtii. Molecular characteristics of this gene have been extensively studied. However, little information is available about its regulatory factors in C. reinhardtii. In this study, we isolated a regulatory mutant of FOX1 gene by using an arylsulfatase gene driven by the ...
