ERAF polyclonal antibody

α-hemoglobin stabilizing protein (AHSP), also designated erythroid associated factor (ERAF), is an erythroid-specific protein that acts as a chaperone to prevent the aggregation of α-hemoglobin during normal erythroid cell development.It specifically protects free α-hemoglobin from precipitation in live cells and in solution. It forms a heterodimer with free α-hemoglobin, but not with β-hemoglobin or hemoglobin A (α2-β-2). AHSP localizes to the cytoplasm and is expressed in the blood and bone marrow. The AHSP protein is downregulated
in transmissible spongiform encephalopathies (TSEs). AHSP may regulate pathological states of α-hemoglobin excess such as β-thalassemia,a group of hereditary disorders involving the decreased production of normal adult hemoglobin (HbA) that are characterized by a deficiency in the synthesis of β-globin chains.
