Application

Anti-PRKRA polyclonal antibody is used to tag protein kinase, interferon-inducible double stranded RNA-dependent activator/protein activator of the interferon-induced protein kinase for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to determine the roles of protein activator of the interferon-induced protein kinase (PACT) in stress response, antiviral activity and double-stranded RNA processing.

Biochem/physiol Actions

PRKRA contains 3 DRBM (double-stranded RNA-binding) domains. It appears to have a pro-apoptotic function that may be suppressed in the presence of growth factor and activates EIF2AK2 in absence of double stranded RNA (dsRNA).

General description

Protein kinase, interferon-inducible double stranded RNA-dependent activator/protein activator of the interferon-induced protein kinase (PRKRA, PACT) is a stress-modulated cellular activator of interferon (IFN)-induced double-stranded (ds) RNA-activated protein kinase (PKR) which is involved in antiviral defense in mammals. PACT and Mammalian Dicer interacts with double-stranded RNA-binding protein (TRBP) and associate with Dicer to stimulate cleavage of double-stranded RNA found in short hairpin and short interfering RNA (siRNA).
