The expression plasmids of cGAS, STING, RIG-I N, TBK1, IRF3, IRF3-5D, IκB-sr, HA-Ub-WT and HA-Ub-K0, and luciferase reporter plasmids IFNB-Luc, IRF3-Luc, TK-Luc have been described previously [44 (link),46 (link),81 (link)]. The EBV protein expression library was kindly provided by Lori Frappier from University of Toronto, and the p2089 bacmid was provided by Wolfgang Hammerschmidt from German Center for Infection Research (Munich, Germany). The expression constructs of BPLF1 mutant C61A, HA-Ub-K63, HA-Ub-K48, HA-Ub-K27, HA-Ub-K63R, HA-Ub-K48R were constructed by Q5 Site-Directed Mutagenesis Kit (New England Biolabs). Lenti-MPHv2 and lenti-SAMv2 plasmids [45 (link)] were gifts from Feng Zhang from Broad Institute.
