Quick Overview for EIF2AK2 antibody (pThr446) (ABIN197048)

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

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: This EIF2AK2 antibody is un-conjugated

Application: Western Blotting (WB), Immunofluorescence (IF), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Product Details anti-EIF2AK2 Antibody

Binding Specificity: pThr446

Specificity: This antibody detects endogenous levels of PKR only when phosphorylated at Threonine 446.

Purification: Affinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatogramphy using non-phosphopeptide corresponding to the phosphorylation site.

Immunogen: The antiserum was produced against synthesized phosphopeptide derived from human PKR around the phosphorylation site of threonine 446 (K-R-TP-R-S).

Target Details for EIF2AK2

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

Alternative Name: EIF2AK2 / PKR

Background: PKR is an interferon-inducible serine/threonine specific protein kinase. It is widely expressed in eukaryotic organisms and activated by double stranded RNA. Activation of PKR by dsRNAs leads to autophosphorylation at multiple sites. Phosphorylation of Thr446 and Thr451 in the PKR activation loop is required in vivo and in vitro for high level kinase activity. PKR phosphorylates its natural substrate, the alpha subunit of eukaryotic protein synthesis initiation factor 2 (EIF2 alpha), leading to the inhibition of protein synthesis. PKR is also involved in TLR signaling and mediates apoptosis in fibroblasts in response to viral infection and inflammatory cytokines, and also activates IKK and NFKB, thereby suppressing apoptosis. Recently, it has been reported that PKR also phosphorylates human p53 on serine 392. PKR might play a role in ER stress-induced apoptosis and in Alzheimer's disease. Alzheimer cases show prominent PKR activation in association with neuritic plaques and pyramidal neurons in the hippocampus and neocortex.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
