Description

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.

Antigen Details

Structure
47 Kd protein contains DNA binding domain
Distribution

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.

Function
IRF-3 is a constitutively expressed, latent transcription factor that plays a pivotal role in type I IFN response.
Interaction
CREB binding protein, IRF-7, TICAM-1, TICAM-2, non-canonical IKB kinases TBK1 and IKKε
