Related Product Information for anti-HRI antibody

Inhibits protein synthesis at the level of translation initiation, in response to various stress conditions, including oxidative stress, heme deficiency, osmotic shock, and heat shock. It exerts its function through the phosphorylation of EIF2S1 in ‘Ser-48’ and ‘Ser-51’, thus avoiding their recycling. It binds to hemin forming a 1: 1 complex through nitrogen coordination of cysteine ​​thiolate and histidine. This binding occurs with moderate affinity, allowing you to detect the concentration of heme within the cell.

Thanks to this unique heme detection ability, plays a crucial role in stopping protein synthesis during acute heme deficiency conditions. In red blood cells (RBC), it controls the synthesis of hemoglobin, ensuring a coordinated regulation of the synthesis of its heme and globin residues. Therefore, it plays an essential protective role in the survival of red blood cells in iron deficiency anemia. Similarly, hepatocytes, involved in the heme-mediated translation control of CYP2B and CYP3A and possibly other hepatic P450 cytochromes. It can also contain ER stress during acute heme deficiency conditions.
