Protein kinase
Protein kinase, interferon-inducible double stranded RNA dependent activator, also known as interferon-inducible double stranded RNA-dependent protein kinase activator A or Protein ACTivator of the interferon-induced protein kinase (PACT) is a protein that in humans is encoded by the "PRKRA" gene. PACT heterodimerizes with and activates protein kinase R.
