This antibody is validated for use in Western Blot and Immunofluorescence. PKR is encoded by the 5610 gene, also known as Protein kinase RNA-activated, EIF2AK2, p68 kinase. Double-stranded RNA-dependent protein kinase (PKR) is a 68 kDa protein that is induced by interferon and double-stranded RNAs (dsRNA) produced in virus-infected cells (1). Two dsRNA-binding domains in the N-terminus interact with dsRNA to modify the conformation of PKR and allow it to undergo autophosphorylation and activation. Once activated, PKR phosphorylates eIF2α, leading to inhibition of protein synthesis, growth suppression, and apoptosis induction (2-4). The phosphorylation of two sites in the activation loop of the kinase domain, threonines 446 and 451 is critical for high level catalytic activity (5 and 6).1. Vorburger, S.A., et al.
