Name Interferon-induced, double-stranded RNA-activated protein kinase
Description Not Available
Synonyms
  1. Eukaryotic translation initiation factor 2-alpha kinase 2
  2. Interferon-inducible RNA-dependent protein kinase
  3. P1/eIF-2A protein kinase
  4. PKR
  5. Protein kinase RNA-activated
  6. eIF-2A protein kinase 2
  7. p68 kinase
Gene Name EIF2AK2
Protein Type Enzyme
Biological Properties
General Function Involved in double-stranded RNA binding
Specific Function Following activation by double-stranded RNA in the presence of ATP, the kinase becomes autophosphorylated and can catalyze the phosphorylation of the translation initiation factor EIF2S1, which leads to an inhibition of the initiation of protein synthesis. Double-stranded RNA is generated during the course of a viral infection
