Interferon-Inducible Double-Stranded RNA-Dependent Protein Kinase Activator A

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Interferon-inducible double-stranded RNA-dependent protein kinase activator A (313 aa, ~34 kDa) is encoded by the human PRKRA gene. This protein is involved in RNA-induced silencing of transcription and the regulation of antiviral responses that are mediated by interferon and double-stranded RNA.

**Synonyms:** - PKR-Associated Protein X - PKR-Associating Protein X - PRKRA - Protein Activator of Interferon Induced Protein Kinase EIF2AK2 - Protein Activator of the Interferon-Induced Protein Kinase - Protein Kinase, Interferon-Inducible Double-Stranded RNA-Dependent Activator
