Transcription factor involved in the induction of interferons IFNA and INFB and inflammatory cytokines upon virus infection. Activated by TLR7 or TLR8 signaling. Homodimer, when phosphorylated. Belongs to the IRF family. 4 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Biological Process: positive regulation of apoptosis; positive regulation of interferon-alpha production; positive regulation of interferon-beta production; positive regulation of interleukin-12 production; positive regulation of transcription from RNA polymerase II promoter; response to muramyl dipeptide; response to peptidoglycan
