description | Viral protein involved in the evasion of host innate defense by inhibiting the DDX58/RIG-I-like receptor (RLR) pathway leading to the triggering of interferon-mediated response. This pathway starts with the recognition of viral RNA by host proteins including DDX58/RIG-I or IFIH1. Then, the signal is transmitted through MAVS and TRAFs leading to the activation and nuclear localization of transcription factors IRF3 and IRF7 to induce IFNalpha/beta transcription and protein production. Many viruses interact with components of this pathway to inhibit production of interferons and establishment of the antiviral state |
