interferon regulatory factor 3, a member of the interferon regulatory transcription factor (IRF) family. IRF3 is found in an inactive cytoplasmic form that upon serine/threonine phosphorylation forms a complex with CREBBP. This complex translocates to the nucleus and activates the transcription of interferons alpha and beta, as well as other interferon-induced genes. Note: This description may include information from UniProtKB.
Protein type: Transcription factor; DNA binding protein
Molecular Function: identical protein binding; protein binding; protein homodimerization activity; DNA binding; transcription cofactor activity; transcription factor activity
