Anti-HFE2 antibodies are protein reagents that detect specific antigens. The HFE2 antigen is another term for the human protein hemojuvelin BMP co-receptor, encoded by the HJV gene. The protein is known to act as a bone morphogenetic protein (BMP) coreceptor. Canonically, it has an amino acid length of 426 residues and a mass of 45.1 kilodaltons. Its subcellular localization is in the cell membrane. The HFE2 protein is a member of the Repulsive guidance molecule (RGM) protein family. ELISA, Western Blot, and Immunohistochemistry are common applications for HFE2 antibodies.
