Target Information

EIF2AK2 (PKR) is one of four kinases that specifically phosphorylate Ser51 of translation initiation factor eIF2-alpha in response to various environmental stresses.
EIF2AK2 plays a key role in antiviral defense mediated through its direct activation by double-stranded RNA produced by viral infection.

PKR is involved in IFN-induced innate antiviral response, virus-induced apoptosis, and cell growth & differentiation. It induces apoptosis by up-regulating Fas expression and mediates the FADD/Caspase-8 death signaling pathway.

Upon viral infection, PKR functions as a dual protein, sequentially activating both cell survival and cell death pathways using kinase-independent and -dependent strategies. PRKR regulates multiple pathways including NF-kappaB activation, p53, p38, and PDGF signaling.

PKR has been implicated in tumor suppression and malignancy. To evade PKR’s antiviral effects, viruses have evolved mechanisms such as inhibition by influenza virus NS1 protein.
More recently, PKR has been linked to neurodegenerative diseases including Alzheimer’s, Huntington’s, and amyotrophic lateral sclerosis.
