Characterization of erythroid differentiation related factor (EDRF): a novel a-globin binding protein. Hemoglobin, a four-subunit protein comprising two alpha and two beta polypeptide chains, is the essential oxygen transporter found in all mammals. Problems with the synthesis of hemoglobin can give rise to a range of common and serious human disorders, including thalassaemia and anemia. We have discovered a protein, EDRF, that appears to interact directly with alpha-globin (but not beta-globin) ....Characterization of erythroid differentiation related factor (EDRF): a novel a-globin binding protein. Hemoglobin, a four-subunit protein comprising two alpha and two beta polypeptide chains, is the essential oxygen transporter found in all mammals. Problems with the synthesis of hemoglobin can give rise to a range of common and serious human disorders, including thalassaemia and anemia. We have discovered a protein, EDRF, that appears to interact directly with alpha-globin (but not beta-globin) and to play a role in the regulation of hemoglobin production. We now seek to understand the nature of this interaction at a molecular level and mechanistic level.Read moreRead less
