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.
Protein type: DNA binding protein; Transcription factor
Cellular Component: cytoplasm; nucleus; cytosol
Molecular Function: protein binding; transcription factor activity
Biological Process: transcription, DNA-dependent; positive regulation of apoptosis; response to muramyl dipeptide; positive regulation of interleukin-12 production; cytokine and chemokine mediated signaling pathway; response to peptidoglycan; positive regulation of interferon-beta production; positive regulation of transcription from RNA polymerase II promoter; defense response to virus; positive regulation of interferon-alpha production
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
