Target Information
EIF2AK2 (PKR) is one of four kinases that specifically phosphorylate Ser51 of translation initiation factor eIF2-alpha in response to environmental stresses. PKR plays a critical role in antiviral defense through activation by double-stranded RNA produced during viral infection. It is involved in IFN-induced innate antiviral responses, virus-induced apoptosis, and regulation of cell growth and differentiation.
PKR induces apoptosis by upregulating Fas expression and mediates the FADD/Caspase-8 death signaling pathway. Upon viral infection, PKR functions as a dual protein, activating both cell survival and death pathways via kinase-independent and dependent mechanisms. It regulates multiple pathways, including NF-kappaB activation, p53, p38, and PDGF signaling. PKR has been implicated in tumor suppression, malignancy, and several neurodegenerative diseases such as Alzheimer’s, Huntington’s, and amyotrophic lateral sclerosis.
