Expression and Polarized Localization of the Hemochromatosis Gene Product HFE in Retinal Pigment Epithelium

Abstract excerpt

PURPOSE: Hereditary hemochromatosis is an autosomal recessive disorder of iron overload leading to oxidative stress. Mutations in HFE are responsible for approximately 90% of cases of this disease. HFE is the principal regulator of iron homeostasis, and the process involves interaction with transferrin receptor (TfR)-1, transferrin receptor (TfR)-2, and beta2-microglobulin (beta2M). Expression of HFE has not been...
