Interaction of the Hemochromatosis Gene Product HFE with Transferrin Receptor Modulates Cellular Iron Metabolism

Mutations of a novel MHC class I-like protein, termed HFE, have been found in the vast majority of patients with the iron overload disease heredity hemochromatosis. Identification of HFE is likely to shed light on one of the major enigmas of mammalian iron homeostasis: How is intestinal iron absorption regulated?
