In this study, we demonstrate for the first time that HACE1 contributes to negative regulation of the virus-induced type I IFN signaling via disrupting the MAVS-TRAF3 complex. HACE1 suppressed virus-induced type I IFN signaling independently of its ubiquitin E3 ligase activity. By a small-scale screening of unknown ubiquitin E3 ligases in the regulation of virus-induced type I IFN signaling by the dual-luciferase reporter, we identified HACE1 as a potential negative regulator in this pathway.
