Descripción general

An imidazolo-oxindole compound that acts as a potent, ATP-binding site directed inhibitor of PKR. Shown to effectively inhibit RNA-induced PKR autophosphorylation (IC50 = 210 nM) and rescue PKR-dependent translation block (IC50 = 100 nM). The solid form of this compound (Cat. No. 527450) is also available.

The RNA-dependent protein kinase (PKR) is an interferon-induced serine/threonine protein kinase that phosphorylates the alpha subunit of the eukaryotic initiation factor 2 in response to viral infection. Classical genetic approaches for studying the role of PKR in cell signaling have

The double-stranded RNA-activated protein kinase (PKR) was originally identified as a sensor of virus infection, but its function in the brain remains unknown. Here, we report that the lack of PKR enhances learning and memory in several behavioral tasks while

Stress granules (SGs) are cytoplasmic assemblies formed under various stress conditions as a consequence of translation arrest. SGs contain RNA-binding proteins, ribosomal subunits and messenger RNAs (mRNAs). It is well known that mRNAs contribute to SG formation; however, the connection between SG
