Web8 mei 2024 · As the globin subunit synthesis is a critical portion of hemoglobin synthesis, the thalassemias are relevant and clinically significant hematologic disorders. Alpha-thalassemia occurs with decreased or absent production of alpha-globin subunits. Beta-thalassemia occurs with reduced or absent production of beta-globin subunits. Web1 nov. 2000 · Protein synthesis in reticulocytes depends on the availability of heme. In heme deficiency, inhibition of protein synthesis correlates with the activation of heme-regulated eIF-2α kinase (HRI), which blocks the initiation of protein synthesis by phosphorylating eIF-2α. HRI is a hemoprotein with 2 distinct heme-binding domains.
