NS3 has no interferon and PKR antagonistic properties. NS3 has no interferon and PKR antagonistic properties. HEK293T cells were co‐transfected with expression vectors encoding firefly luciferase under the control of an IFN‐β‐inducible promoter, Renilla luciferase, and VP35, NS3 (10, 100 and 400 ng) or pBluescript (C), either in the presence (+) or absence (−) of poly I:C. Luciferase expression was measured 3 days post‐transfection. A relative luciferase expression corrected for the internal Renilla control (firefly/Renilla) is shown. The mean of at least three independent experiments is shown with standard error. HEK, human embryonic kidney; IFN, interferon; NS3, non‐structural protein 3; PKR, protein kinase R.
