Upon detection of viral RNA, retinoic acid inducible gene I (RIG-I) undergoes TRIM25-mediated Lys-63 linked ubiquitination, leading to type-I interferon (IFN) production. In this study, we demonstrate that the linear ubiquitin assembly complex (LUBAC), comprised of two RING-IBR-RING (RBR)-containing E3 ligases HOIL-1L and HOIP, independently targets TRIM25 and RIG-I to effectively suppress virus-induced IFN production. RBR E3 ligase domains of HOIL-1L and HOIP bind and induce proteosomal degradation of TRIM25, whereas the NZF domain of HOIL-1L competes with TRIM25 for RIG-I binding. Consequently, both actions by the HOIL-1L/HOIP LUBAC potently inhibit RIG-I ubiquitination and anti-viral activity, but in a mechanistically separate manner. Conversely, the genetic deletion or depletion of HOIL-1L and HOIP robustly enhances virus-induced type-I IFN production. Taken together, the HOIL-1L/HOIP LUBAC specifically suppresses RIG-I ubiquitination and activation by inducing TRIM25 degradation and inhibiting TRIM25 interaction with RIG-I, resulting in the comprehensive suppression of the IFN-mediated anti-viral signaling pathway.
