The antiviral protein kinase pkr inhibits protein synthesis by phosphorylating the translation initiation factor eif2alpha on ser51the protein kinases pkr, hri, perk, and gcn2 specifically phosphorylate ser51 on the _ subunit of the translation initiation factor eif2, a gtp binding protein that delivers the initiator methionyl-trna to the small ribosomal subunit in the first step of translation initiation. Phosphorylation of eif2_ converts eif2 from a substrate to an inhibitor of its gdp-gtp exchange factor eif2b, thereby blocking protein synthesis |

Besides PERK, eIF2α can also be phosphorylated by three other kinases: heme-regulated inhibitor kinase (HRI), general control nonderepressible 2 (GCN2), and PKR. PKR is an interferon-stimulated gene (ISG) activated by binding of double-stranded RNA (dsRNA), a common intermediate during the replication of DNA and RNA viruses. Together, these four eIF2α kinases and their convergent downstream signaling pathways are known as the integrated stress response (ISR) |

Translation initiation is inhibited in cells exposed to different stressful conditions. The phosphorylation of the α subunit of eukaryotic translation initiation factor 2 (eIF2α) plays an important role in this stereotyped response, and is mediated by distinct kinases that are activated by specific stress signals. When phosphorylated on serine 51, eIF2α binds to and inhibits the guanine nucleotide exchange factor, eIF2B. The latter is required for the formation of the eukaryotic translational preinitiation complexes, and its sequestration in an inactive complex with phosphorylated eIF2α inhibits the initiation step of protein synthesis. |

HRI is a heme-regulated kinase that phosphorylates the α-subunit of eIF2 in heme deficiency, impairing another round of translational initiation and thereby inhibiting translation. |

ER stress, viral infection, and other cellular stress signals activate PERK, PKR, HRI, and GCN2 kinases that converge on phosphorylation of eIF2alpha, the core of ISR. This leads to global attenuation of Cap Âdependent translation while concomitantly initiates the preferential translation of ISR Âspecific mRNAs, such as ATF4. ATF4 is the main effector of the ISR. eIF2alpha phosphorylation causes a reduction in global protein synthesis while allowing the translation of selected genes including activating transcription factor 4 (ATF4), aiding cell survival and recovery |

Dephosphorylation of eIF2α is central to ISR signal termination to restore protein synthesis and normal cell functioning. It is mediated by protein phosphatase 1 (PP1) complex that recruits a PP1 catalytic subunit (PP1c) and one of the two regulatory subunits. In mammals, phosphatase activity is regulated by either PPP1R15A (also known as growth arrest and DNA damageâ€inducible protein, GADD34), which is induced as part of the ISR. the GADD34–PP1 complex acts as an important negative feedback loop to restore protein synthesis once the ER stress has been resolved, and as such aids in cell survival |

The CUGBP1-eIF2 complex is bound to C/EBPbeta mRNA in the liver of old animals, and this binding correlates with the increased amounts of liver-enriched activator protein and liver-enriched inhibitory protein. |
