HFE protein | definition of HFE protein by Medical dictionary
Also found in: Dictionary
A protein normally found intracellularly in duodenal crypt enterocytes and the placenta. It is closely associated with transferrin receptors for iron and regulates iron absorption. HFE is a homologue of class I major histocompatibility complex (MHC) molecules. The C2824 and H63D mutations on chromosome 6 in the HFE gene cause hemochromatosis.

as a cell-surface receptor for some infectious agents (58) or to the relative iron deficiency that occurs in the macrophages in the presence of the C282Y sequence variant, and offers a possible protection against many virulent species of bacteria that multiply mainly in iron-rich macrophages, such as Mycobacterium tuberculosis and Yersinia pestis (59).
