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.
Molecular Function: DNA binding; identical protein binding; protein binding; protein homodimerization activity; transcription cofactor activity
Biological Process: apoptosis; defense response to virus; interferon type I biosynthetic process; lipopolysaccharide-mediated signaling pathway; negative regulation of interferon type I production; negative regulation of transcription from RNA polymerase II promoter; positive regulation of cytokine secretion; positive regulation of I-kappaB kinase/NF-kappaB cascade; positive regulation of interferon type I production; positive regulation of interferon-alpha production; positive regulation of interferon-beta production; response to DNA damage stimulus; response to exogenous dsRNA; transcription from RNA polymerase II promoter; viral reproduction
LTP: 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.
