Web24 feb. 2024 · HRI is activated in response to a number of environmental conditions, including heme deficiency, heat shock, and oxidative stress. Autophosphorylation is essential for the activation of HRI, which causes an arrest of initiation of protein synthesis. Both HSP 90 and HSC 70 are necessary for all stress-induced HRI activation. Web25 feb. 2024 · Since HRI is nearly indispensable for ATF4 activation by GSK-J4 (Fig. 4 A), it is likely that GSK-J4 activates HRI by causing mitochondrial stress. Mechanisms of the HRI activation by GSK-J4 and suppression of UTX can be explained as follows. First, UTX demethylates a target protein and thereby induces mitochondrial stress in some way.
