HFE
HFE is named after High Fe (iron). The gene products known function is to regulate iron absorption by interacting with the transferrin receptor (TfR). When the normal function is disrupted by mutation the result can be HFE hereditary hemochromatosis or iron overload.
DNA Sequence
HFE is located on chromosome 6 in humans.
RNA Sequence
There are several alternatively spliced variants of HFE.
Protein Sequence
The protein has a signal sequence and transmembrane domain. It forms a tertiary complex with beta2-microglobulin (beta2M) and TfR. HFE has sequence and structural similarity to MHC class I-type proteins.
