WebNov 20, 2024 · IRF3 is constitutively expressed and resides in the cytosol in its latent form. Posttranslational modifications (PTMs), including phosphorylation and polyubiquitination, are key features of signal transduction pathways that allow the modulation of protein function ( Deribe et al., 2010; Mowen and David, 2014; Liu et al., 2016 ). WebHere we define GnT interactions and residues required to inhibit TRAF3-TBK1 directed IFNβ induction and IRF3 phosphorylation. We observed that GnTs bind TRAF3 via residues within the TRAF-N domain (392-415) and that binding is independent of the MAVS interactive TRAF-C domain (415-568). We determined that GnT binding to TRAF3 is mediated by C ...

WebAug 3, 2007 · Phosphorylation at site 1 is, in turn, required for IRF-3 dimerization. The data support a two-step phosphorylation model for IRF-3 activation mediated by TBK1.
