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.^[5]^[6]^[7] PACT heterodimerizes with and activates protein kinase R.^[6]^[8] PRKRA mutations have been linked to a rare form of dystonia parkinsonism.^[9]
