We use unbiased screening to identify SARS-CoV-2 proteins that antagonize type I interferon (IFN-I) response. We found three proteins that antagonize IFN-I production via distinct mechanisms: nonstructural protein 6 (nsp6) binds TANK binding kinase 1 (TBK1) to suppress interferon regulatory factor 3 (IRF3) phosphorylation, nsp13 binds and blocks TBK1 phosphorylation, and open reading frame 6 (ORF6) binds importin Karyopherin α 2 (KPNA2) to inhibit IRF3 nuclear translocation. the results indicate that (1) nsp6 binds to TBK1 without affecting TBK1 phosphorylation, but the nsp6/TBK1 interaction decreases IRF3 phosphorylation, which leads to reduced IFN-β production; and (2) nsp13 binds and inhibits TBK1 phosphorylation, resulting in decreased IRF3 activation and IFN-β production (Figure 2F). |
