Besides its main deubiquitinase activity as part of the viral replication-transcription complex, SARS-CoV-1 papain-like protease (PLpro, nsp3) also binds directly to IRF3, inhibiting IRF3 phosphorylation and subsequent dimerization, nuclear translocation, and activation of expression of IRF-3 target genes (Devaraj et al, 2007; Chen et al, 2014). This binding probably happens in cytosol, where nascent IRF3 is localized.
