WebApr 11, 2024 · In the TLR4-TRIF-IRF3-type I IFN signaling cascade, phosphorylation of the TBK1 kinase is a key step 2. Phosphorylated-TBK1 (pTBK1) subsequently phosphorylates IRF3, which then translocates... WebDistinct protein-interaction motifs allow recruitment of the effector proteins TBK1, TRAF6 and RIPK1, which in turn, lead to the activation of transcription factors IRF3 and IRF7, NF-kappa-B and FADD respectively ( PubMed: 12471095, …
Frontiers Direct Inhibition of IRF-Dependent
WebAug 11, 2009 · IRF3 and IRF7 activation is mediated by a wide range of phosphorylation events, many of which are directly induced by the IKK-related kinases to coordinate protein dimerization, nuclear translocation, DNA binding, and the induction of IFNβ [ 8, 20-24 ]. 3. The IKK complex WebMechanistically, RIKA was mediated by the direct binding of IRF3 to the p65 subunit of NF-κB in the cytoplasm, which prevented its nuclear import. A mutant IRF3 defective in both the transcriptional and the apoptotic activities was active in RIKA and inhibited virus replication. permissions trusted installer
