A detailed analysis revealed that mutations (H48A, C160A, or H48A/C160A) that ablate the Cys and His residues of 3C(pro) abrogated its deubiquitinating activity and the ability of 3C(pro) to block IFN-β induction. To determine whether SVV can evade innate immune response by inhibiting the host ubiquitination, HEK293T cells were transfected with FLAG-tagged VP1, VP2, 2AB, 2B, 2C, 3D, 3C plasmids along with HA-Ub plasmid. As shown in Fig. 1A , expression of 3C pro resulted in a dose-dependent reduction of the level of ubiquitinated cellular proteins compared with that in the empty vector-transfected cells. Taken together, these results indicate that SVV and 3C pro inhibit the ubiquitination of RIG-I, TBK1, and TRAF3 in a DUB-dependent manner. ./cache/cord-299964-sn5o3ugb.txt ./txt/cord-299964-sn5o3ugb.txt
