WebBeta-globin is a component (subunit) of a larger protein called hemoglobin, which is located inside red blood cells. In adults, hemoglobin consists of four protein subunits: usually two subunits of beta-globin and two subunits of a protein called alpha-globin, which is produced from another gene called HBA.
