Interferon (show IFNA ELISA Kits) regulatory factor (IRF (show TRIM63 ELISA Kits))10 inhibits the expression of IFN1 and IFN3 to avoid an excessive immune response, a unique regulation mechanism of the IFN responses in lower vertebrates.
Hepatitis A virus protein 2B suppresses beta interferon (show IFNA ELISA Kits) (IFN) gene transcription by interfering with IFN regulatory factor 3 activation.
MyD88 (show MYD88 ELISA Kits) interacts with interferon (show IFNA ELISA Kits) regulatory factor (IRF) 3 and IRF7 (show IRF7 ELISA Kits) in Atlantic salmon (Salmo salar)
rotavirus NSP1 (nonstructural protein 1) employs a pLxIS motif to target IRF-3 for degradation, but phosphorylation of NSP1 is not required for its activity. These results suggest a concerted mechanism for the recruitment and activation of IRF-3 that can be subverted by viral proteins to evade innate immune responses.
Highly pathogenic Porcine reproductive and respiratory syndrome virus modulates Interferon-beta (show IFNB1 ELISA Kits) expression mainly through attenuating IRF-3 phosphorylation.
Data suggest that molecular chaperone (show HSP90AA1 ELISA Kits) GRP78 (show HSPA5 ELISA Kits) contributes to toll-like receptor-3 (TLR3 (show TLR3 ELISA Kits))-mediated, interferon regulatory factor 3 protein (IRF3)-dependent innate immune response to hepatitis C virus (HCV) in hepatocytes.
Findings suggest a common and conserved mechanism through which highly pathogenic MERS-CoV and SARS (show SARS ELISA Kits)-CoV harness their M proteins to suppress type I IFN expression at the level of TBK1 (show TBK1 ELISA Kits)-dependent phosphorylation and activation of IRF3 resulting in evasion of the host innate antiviral response.
observations suggest IRF3 may function as a novel regulator to modulate TGF-beta1 (show TGFB1 ELISA Kits)-induced LX-2 proliferation, at least in part, via AKT (show AKT1 ELISA Kits) signaling pathway
FAF1 (show FAF1 ELISA Kits) plays a novel role in negatively regulating virus-induced IFN-beta (show IFNB1 ELISA Kits) production and the antiviral response by inhibiting the translocation of active, phosphorylated IRF3 from the cytosol to the nucleus
the LxxLL motifs of IRF3 binds within the hydrophobic pocket of E6, precluding Ser (show SIGLEC1 ELISA Kits)-patch phosphorylation, necessary for IRF3 activation and interferon (show IFNA ELISA Kits) induction.
the suppression of type I IFN production by HTLV-1 Tax (show CNTN2 ELISA Kits) through interaction with and inhibition of TBK1 (show TBK1 ELISA Kits) kinase that phosphorylates IRF3
The authors found that Ca(2 (show CA2 ELISA Kits)+) signaling associated with membrane perturbation and recognition of incoming viral genomes by cytosolic nucleic acid receptors are required to activate IRF3 in response to Sendai virus and human cytomegalovirus.
Study identifies crosstalk between PTEN and IRF3 in tumor suppression and innate immunity.
Amino acid residues in the N-terminal domain of Npro are involved in the stability of Npro, in interaction of Npro with IRF-3 and subsequent degradation of IRF-3, leading to downregulation of IFN-alpha (show IFNA ELISA Kits)/beta production.
The obtained results showed that PRRSV nsp1 could inhibit Poly(I:C)-induced IFN-beta (show IFNB1 ELISA Kits) promoter activity in MARC (show CCL7 ELISA Kits)-145 cells by down-regulating the protein level of IRF-3 and inhibiting the phosphorylation of IRF-3.
proteasomal degradation of IRF3 is induced by a direct or indirect interaction with N(pro).
Data show that the formation of a tripartite ribosomal protein S6 kinase 1 (S6K1 (show RPS6KB1 ELISA Kits))-STING membrane protein-TANK-binding kinase 1 (TBK1 (show TBK1 ELISA Kits)) complex was necessary for the activation of interferon regulatory factor-3 (IRF3).
characterizes SREBP cleavage-activating protein as an essential adaptor in the STING signaling pathway
results revealed a new paradigm in which the antiviral host factor, IRF3, plays a cell-intrinsic pro-parasitic role.
Irf3/IFN activation in hematopoietic stem and progenitor cells expands multipotent progenitors fractions but inhibits HSC (show FUT1 ELISA Kits) mobilization
find that IRF3 versus ISGF3 (show IRF9 ELISA Kits) specificity may be critical to limiting IFN-beta (show IFNB1 ELISA Kits) production and ISGF3 (show IRF9 ELISA Kits) activation, temporally and spatially, but that partial overlap in their specificity is tolerable and may enhance the effectiveness of the innate-immune response
Bipartite nuclear localization signal controls nuclear import and DNA-binding activity of IRF3.
Our findings delineate a novel mechanism for the termination of IRF3 activation in nucleus through TRIM26 (show TRIM26 ELISA Kits)-mediated IRF3 ubiquitination and degradation.
PP1 (show PPP1CC ELISA Kits) directly interacts with IRF3 and dephosphorylates IRF3 at Ser385 and Ser396, resulting in the suppression of TLR- and RLR (show DHX58 ELISA Kits)-triggered IFN-beta (show IFNB1 ELISA Kits) production.
our results identify CK2 (show CSNK2A1 ELISA Kits) as a novel regulator of TBK1 (show TBK1 ELISA Kits) and IRF3 and suggest that targeting CK2 (show CSNK2A1 ELISA Kits) by small molecular inhibitor may be a viable approach to prevent and treat viral infections.
The authors demonstrate that bovine herpesvirus 1 bICP0 effectively inhibits bovine IFN-beta (show IFNB1 ELISA Kits) promoter activity and induces IRF3 degradation.
cpBVDV infection causes a marked loss of interferon regulatory factor 3 (IRF-3), a cellular transcription factor that controls interferon (show IFNA ELISA Kits) synthesis.
This gene encodes a member of the interferon regulatory transcription factor (IRF) family. The encoded protein is found in an inactive cytoplasmic form that upon serine/threonine phosphorylation forms a complex with CREBBP. This complex translocates to the nucleus and activates the transcription of interferons alpha and beta, as well as other interferon-induced genes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
