Web7 feb. 2024 · ATF4 is a cellular stress induced bZIP transcription factor that is a hallmark effector of the integrated stress response. The integrated stress response is triggered by phosphorylation of the alpha subunit of the eukaryotic initiation factor 2 complex that can be carried out by the cellular stress responsive kinases; GCN2, PERK, PKR, and HRI. … WebATF4 is regulated by phosphorylation of the eukaryotic translation initiation factor 2α (eIF2α). eIF2α is activated by four kinases (GCN2, PERK, HRI, and PKR). 4) GCN2 is activated by amino acid depletion. PERK is triggered by endoplasmic reticulum (ER) stress. HRI is activated by heme deficiency or arsenite treatment.

Web6 jul. 2024 · The assembly of α-synuclein containing fibrils in the cytosol (as observed in PD) also alters the cytosolic folding environment and triggers HRI-dependent ISR signaling: Heat shock proteins, which normally keep HRI in an inactive state, are recruited away from HRI to associate with the forming fibrils, which results in the expression of ATF4 and … WebATF4 induction by GSK-J4 was due to neither transcriptional nor post-translational regulation. In support of this view, the ATF4 induction was almost exclusively dependent on the heme-regulated eIF2α kinase (HRI) in mouse embryonic fibroblasts (MEFs).
