    Epiregulin (EPR), a novel member of epidermal growth factor (EGF) family, is a ligand for ErbB-1 and ErbB-4 receptors. The binding affinity of EPR for the receptors is lower than those of other EGF-family ligands. The solution structure of EPR was determined using two-dimensional nuclear magnetic resonance spectroscopy. The secondary structure in the C-terminal domain of EPR is different from other EGF-family ligands because of the lack of hydrogen bonds. The structural difference in the C-terminal domain may provide an explanation for the reduced binding affinity of EPR to the ErbB receptors.
