NCIt definition : Interferon regulatory factor 3 (427 aa, 47 kDa) is encoded by the human IRF3 gene.
This protein plays a role in the modulation of both antiviral activity and interferon-stimulated
response element promoter activation.;
NCIt note : 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. (EntrezGene);
