Rabbit Polyclonal Antibody
Manufacturer: Proteintech Group Inc 182441AP
This antibody is specific to EIF2AK2.PKR is a 68 kDa protein and an IFN-induced serine/threonine protein kinase consisting of two N-terminal RNA-binding regulatory domains and a functional C-terminal serine/threonine protein kinase domain. Activated by dsRNA produced during viral infections, PKR plays a key role in IFN induced-innate antiviral response, virus-induced apoptosis, cell growth & differentiation. Upon activation, PKR gets autophosphorylated and catalyzes the phosphorylation of elF2 alpha subunit, which leads to an inhibition of protein synthesis. PKR induces apoptosis by up-regulating Fas expression and mediates FADD/Caspase-8 death signaling pathway. Upon viral infection, it functions as a dual protein, sequentially activating both cell survival & cell death pathways using kinase independent and dependent strategies. PRKR regulates multiple pathways which include NF-kappaB activation, p53, p38, & PDGF signaling pathway. PKR has been implicated in tumor suppression & maligcy. To evade the antiviral effects of PKR, viruses have evolved multiple mechanisms, such as the inhibition of PKR by the non-structural protein (NS1) of the influenza virus. More recently, PKR has been implicated in several neurodegenerative diseases including Alzheimer, Huntington, and amyotrophic lateral sclerosis.
