IRF-3 is a member of the interferon regulatory transcription factor (IRF) family. It mediates interferon-stimulated response element (ISRE) promoter activation and functions as a molecular switch for antiviral activity. DsRNA generated during the course of a viral infection leads to IRF-3 phosphorylation on the C-terminal serine/threonine cluster. This induces a conformational change, leading to its dimerization, nuclear localization and association with CREB protein binding to dsRNA-activated factor 1, a complex which activates the transcription of genes under control of ISRE. The phosphorylated IRF-3 is under negative regulation by ubiquitin-mediated degradation. Recent research indicates that it plays a critical role in stimulated TLR-mediated IL-27 P28 gene expression.Product Details

Inactive IRF3 continuously transits between the cytoplasm and nucleus. Serine/threonine phosphorylation or IRF-3 results in the structural changes which allow IRF-3 activation. The activated IRF3 translocates to the nucleus, where it forms complex with CREB binding protein and activates the transcription of interferons, interferon stimulated genes and other antiviral response genes.
- IRF-3 is a constitutively expressed, latent transcription factor that plays a pivotal role in type I IFN response.
