IRF3 - Interferon regulatory factor 3 - Function

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 … product olayWebIn contrast, the phospho-mimetic T404E mutation led to stronger binding (Fig. 3B). In addition, STING recruited less IRF3 in cells expressing T404E-STAT2 (Fig. 3B).
