Mediates interferon-stimulated response element (ISRE) promoter activation. Functions as a molecular switch for antiviral activity. DsRNA generated during the course of an viral infection leads to IRF3 phosphorylation on the C-terminal serine/threonine cluster. This induces a conformational change, leading to its dimerization, nuclear localization and association with CREB binding protein (CREBBP) to form dsRNA-activated factor 1 (DRAF1), a complex which activates the transcription of genes under the control of ISRE. The complex binds to the IE and PRDIII regions on the IFN-alpha and IFN-beta promoters respectively. IRF-3 does not have any transcription activation domains (By similarity).
Titration of the Irf3 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
A portion of amino acids 46-72 from the mouse protein was used as the immunogen for this Irf3 antibody.
Aliquot the Irf3 antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
