This study identifies an interaction between Epstein-Barr virus (EBV) SM protein and cellular helicase DHX9, exploring the roles that this interaction plays in viral infection and host defenses. Whereas most previous studies established DHX9 as a proviral factor, we demonstrate that DHX9 may act as an inhibitor of EBV virion production. DHX9 enhanced innate antiviral pathways active against EBV and was needed for maximal expression of several interferon-induced genes. We show that SM binds to and colocalizes DHX9 and may counteract the antiviral function of DHX9. These data indicate that DHX9 possesses antiviral activity and that SM may suppress the antiviral functions of DHX9 through this association. Our study presents a novel host-pathogen interaction between EBV and the host cell.
