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 ). IRF3 is a member of the interferon regulatory transcription factor (IRF) family. IRF3 was originally discovered as a homolog of IRF1 and IRF2. IRF3 has been further characterized and shown to contain several functional domains including a nuclear export signal, a DNA-binding domain, a C-terminal IRF association domain and several regulatory phosphorylation sites. IRF3 is found … WebViral infection results in phosphorylation of IRF3, leading to its translocation to the nucleus, where it activates promoters containing IRF3-binding sites.

WebPhosphorylated S366 is a docking site for IRF3 and is essential for the subsequent induction of Interferons (IFNs) (7, 8). ... Therefore, in addition to its effect on IRF3 phosphorylation, if it binds to a STING–IRF3 complex, STAT2 may also inhibit the nuclear translocation of IRF3 and thus its transcriptional function. WebIRF3 is constitutively expressed in various types of cells, where it resides in an inactive form with the cytoplasm. On activation of PRR by pathogen infection or stimulation with a synthetic ligands, IRF3 is phosphorylated on specific serine residues by the kinases TANK-binding kinase 1 (TBK1) or inhibitor of NF-κB kinase ε/i (IKKε/i) (9, 10), resulting in … northeast tree identification chartWebAug 3, 2007 · Abstract.

WebMar 12, 2015 · IRF3 activation requires phosphorylation, dimerization and nuclear translocation. However, the mechanisms for the termination of IRF3 activation in nucleus are elusive. Here we report the identification of TRIM26 to negatively regulate IFN-β production and antiviral response by targeting nuclear IRF3. WebSep 15, 2024 · Importantly, it was discovered that UL13 phosphorylates IRF3, and its kinase activity is indispensable for such an inhibitory effect. Moreover, UL13 does not affect IRF3 dimerization, nuclear translocation or association with CREB-binding protein (CBP) but attenuates the binding of IRF3 to the IRF3-responsive promoter.

WebNov 13, 2024 · Here, we unexpectedly found that the IRF3 deficient mice are hyper-susceptible to the development of intestinal tumor in AOM/DSS and Apcmin/+models. Genetic ablation of IRF3 profoundly promotes the proliferation of intestinal epithelial cells via aberrantly activating Wnt signaling. WebOct 22, 2024 · Phosphorylation occurs when IRF3 is recruited to adaptor proteins via a positively charged surface within the regulatory domain of IRF3. This positively charged surface also plays a crucial role in forming the active homodimer by interacting with the phosphorylated sites stabilizing the homodimer.
