    Abstract:
    TBK1 is essential for interferon-β (IFN-β) production and innate antiviral immunity. Here we identified the T cell anergy-related E3 ubiquitin ligase RNF128 as a positive regulator of TBK1 activation. RNF128 directly interacted with TBK1 through its protease-associated (PA) domain and catalyzed the K63-linked polyubiquitination of TBK1, which led to TBK1 activation, IRF3 activation and IFN-β production. Deficiency of RNF128 expression attenuated IRF3 activation, IFN-β production and innate antiviral immune responses to RNA and DNA viruses, in vitro and in vivo. Our study identified RNF128 as an E3 ligase for K63-linked ubiquitination and activation of TBK1 and delineated a previously unrecognized function for RNF128.
