Target Details for EIF2AK2

Target: EIF2AK2 (Eukaryotic Translation Initiation Factor 2-alpha Kinase 2 (EIF2AK2))

Alternative Name: EIF2AK2 / PKR

Background: An interferon-inducible, RNA-dependent protein Serine/Threonine kinase, PKR has various designations. Mouse PKR is known as DAI, dsJ, PI kinase, p65, p67 or TIK, whereas human PKR is known as p68 or p69. PKR phosphorylates its substrate, a subunit of protein synthesis initiation factor eIF-2, on Ser 51 to inhibit translation. PKR contains two dsRNA binding motifs required for its activation by dsRNA. Three kinds of regulation of PKR enzymatic activity occur, and these include transcriptional regulation in response to interferon, an autoregulatory mechanism controlling PKR expression at the level of translation, and post-translational regulation by RNA mediated autophosphorylation. Human PKR contains at least 15 autophosphorylation sites, but only Thr 446 and Thr 451 in the activation loop are critical for its kinase activity. Thr 446 is the in vivo autophosphorylation site of PKR.Synonyms: Eukaryotic translation initiation factor 2-alpha kinase 2, Interferon-induced double-stranded RNA-activated protein kinase, PRKR, Protein kinase RNA-activated, eIF-2A protein kinase 2, p68 kinase
