eukaryotic translation initiation factor 2α kinase 1 (eIF2αK1) inhibitor
Featured Products
Hemin chloride (CAS: 16009-13-5) is an oxidized derivative of heme known to inhibit eukaryotic translation initiation factor 2α kinase 1 (eIF2αK1), a negative regulator of eIF-2α. EIF2α phosphorylation at Ser51 generally transforms eIF2 into an inhibitor of its guanine-nucleotide exchange factor, eIF2β. In biochemical assays, Hemin chloride (20–40 μM) reduces phosphorylation of eIF-2α and eIF-2β, enhancing translation activity in cellular lysates. Animal studies show hemin administration induces heme oxygenase-1 (HO-1) expression and delays thrombus formation in mice, demonstrating its usefulness in translational regulation and vascular biology research.
