Protein kinase R (PKR) is a kinase encoded by the EIF2AK2 gene and is involved in central cellular processes such as mRNA translation, transcriptional control, regulation of apoptosis, and proliferation. PKR plays a key role in the innate immunity pathway and is a mediator of the antiviral effects exerted by interferons. PKR also regulates eIF2α through phosphorylation. Dysregulation of PKR has been implicated in cancer, neurodegenerative disease, inflammation, and metabolic disorders.

The AlphaLISA SureFire Ultra Human Phospho-PKR (Thr451) assay is a sandwich immunoassay for the quantitative detection of phospho-PKR (Thr451) in cellular lysates, using Alpha Technology.
