The cytosolic viral nucleic acid-sensing pathways converge on the protein kinase TANK-binding kinase 1 (TBK1) and the transcription factor interferon (IFN)-regulatory factor 3 (IRF3) to induce type I IFN production and antiviral immune responses. However, the mechanism that triggers the binding of TBK1 and IRF3 after virus infection remains not fully understood. Here, we identified that thousand and one kinase 1 (TAOK1), a Ste20-like kinase, positively regulated virus-induced antiviral immune responses by controlling the TBK1-IRF3 signaling axis. Virus invasion downregulated the expression of TAOK1. TAOK1 deficiency resulted in decreased nucleic acid-mediated type I IFN production and increased susceptibility to virus infection. TAOK1 was constitutively associated with TBK1 independently of the mitochondrial antiviral signaling protein MAVS. TAOK1 promoted IRF3 activation by enhancing TBK1-IRF3 complex formation. TAOK1 enhanced virus-induced type I IFN production in a kinase activity-dependent manner. Viral infection induced TAOK1 to bind with dynein instead of microtubule-associated protein 4 (MAP4), leading to the trafficking of TBK1 to the perinuclear region to bind IRF3. Thus, the depolymerization of microtubule impaired virus-mediated IRF3 activation. Our results revealed that TAOK1 functioned as a new interaction partner and regulated antiviral signaling via trafficking TBK1 along microtubules to bind IRF3. These findings provided novel insights into the function of TAOK1 in the antiviral innate immune response and its related clinical significance.
