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 https://dvbattery.com
