WebOct 22, 2024 · The IRF3, IRF7, MAVS and STING mutant plasmids were generated by site-directed mutagenesis using PfuUltra II Fusion DNA polymerase (Agilent) following the manufacturer’s instructions. 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 …
