NOT KNOWN DETAILS ABOUT PKRRATING

The activated enzyme then phosphorylates its main substrate, the translational initiation variable eIF2α. The resulting translational arrest blocks viral replication. PKR belongs to a conserved family of 4 protein kinases (PKR, PERK, GCN2, HRI) that each one phosphorylate eIF2α in response to distinctive stimuli12, triggering the integrated tensi
