Function

function

Plays an essential role in the inhibition of host immune response. Prevents the establishment of cellular antiviral state by blocking interferon-alpha/beta (IFN-alpha/beta) production and signaling pathway. Interacts with host IFIH1/MDA5 and DHX58/LGP2 to inhibit the transduction pathway involved in the activation of IFN-beta promoter, thus protecting the virus against cell antiviral state. Blocks the type I interferon signaling pathway by interacting with host TYK2 and thereby inhibiting downstream STAT1 and STAT2 phosphorylation. Moderately affects the type II interferon signaling (By similarity).
