Exons: 6 Introns: 5

The product of this gene participates in the regulation of iron metabolism. It is a non-classical major histocompatibility complex (MHC) class I molecule (that is, it does not present peptides to T cells) that interacts with β2-microglobulin, which functions to stabilize surface MHC class I molecules. The interaction of membrane proteins HFE, TFR2 (transferrin receptor) and HJV (hemojuvelin; a BMP co-receptor) in hepatocytes mediates the sensing of elevated iron-bound transferrin in blood plasma, followed by signalling to activate hepcidin production. Binding of HFE to the BMP receptor Alk3 prevents its ubiquitination and proteasomal degradation, thereby implicating the BMP/SMAD signalling pathway in the regulation of hepcidin transcription. Mutations of HFE lead to hereditary haemochromatosis.

Synonyms: HH , HFE1 , HLA-H , MVCD7 , TFQTL2
