PRKRA
Introduction
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.[1][2][3] PACT heterodimerizes with and activates protein kinase R.[2][4] PRKRA mutations have been linked to a rare form of dystonia parkinsonism.[5]
