After triggering antiviral signaling through PRRs (pattern recognition receptors), TBK1 is activated. 2021 Mar 4;10(3):300. doi: 10.3390/pathogens10030300. Epstein-Barr Virus Early Protein BFRF1 Suppresses IFN-β Activity by Inhibiting the Activation of IRF3. The poly(I:C)- or LPS-stimulated phosphorylation of IRF3 at Ser396 and production of IFNβ were greatly reduced in bone marrow-derived macrophages (BMDMs) from TANK knockout (KO) mice crossed to knockin mice expressing the ubiquitin-binding-defective OPTN[D477N] mutant. In contrast with the OPTN-TBK1 complex, TBK1 associated with OPTN[D477N] did not undergo phosphorylation at Ser172 in response to poly(I:C) or LPS, indicating that the interaction of ubiquitin chains with OPTN is required to activate OPTN-TBK1 in BMDM. 5C). Found inside – Page 256Here, we showed that STING stimulates phosphorylation of IRF3 by the kinase TBK1 (TANK-binding kinase 1) in an in vitro reconstitution system.
