Function
NS1_INBLE Binds and inhibits the ubiquitin-like protein G1P2/ISG15, which is an early antiviral protein. Inhibits IRF-3 nuclear translocation and activation. Inhibits IFN-beta promoter activation; this inhibition is not dsRNA-binding dependent Prevents EIF2AK2/PKR activation, either by binding double strand RNA or by interacting directly with EIF2AK2/PKR. Also binds poly(A) and U6 snRNA. Suppresses the RNA silencing-based antiviral response in Drosophila cells.[1]
