Related Product Information for anti-EIF2AK2 antibody

PRKR is a Translational Control type protein kinase. PRKR, induced by interferon (IFN) and activated by double-stranded RNA in the presence of ATP, inhibits translation by phosphorylating the initiation factor eIF2alpha chain. PRKR activation has been linked to the Huntington disease process.

NCBI Description

The protein encoded by this gene is a serine/threonine protein kinase that is activated by autophosphorylation after binding to dsRNA. The activated form of the encoded protein can phosphorylate translation initiation factor EIF2S1, which in turn inhibits protein synthesis. This protein is also activated by manganese ions and heparin. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

Uniprot Description

PKR: a protein kinase of the PEK family. Upon binding double-stranded RNA, it becomes autophosphorylated and activated. Phosphorylates and inhibits the alpha subunit of eIF2 alpha, which leads to an inhibition of the initiation of protein synthesis. Controls the activation of several transcription factors such as NF-kappaB, p53 and Stats. Mediates apoptosis induced by many different stimuli, such as LPS, TNF-alpha, viral infection and serum starvation.
