General description

Interferon regulatory factors (IRFs) comprise a family of transcription factors that function with the Jak/Stat pathway to regulate interferon (IFN) and IFN-inducible gene expression in response to viral infection. IRF-3 can inhibit cell growth and plays a critical role in controlling the expression of genes in the innate immune response. In unstimulated cells, IRF-3 is present in the cytoplasm. Viral infection results in phosphorylation of IRF-3 and leads to its translocation to the nucleus where it activates promoters containing IRF-3-binding sites. Phosphorylation of IRF-3 occurs at a cluster of C-terminal serine and threonine residues (between 385 and 405) leading to its association with the p300/CBP coactivator protein that promotes DNA binding and transcriptional activity.
~50 kDa observed. Uncharacterized bands may appear at ~40 kDa and ~80 kDa in some lysates.

Immunogen

Interferon regulatory factor (IRF)-3 is a critical transcription factor regulating innate immune responses against viral and bacterial infections. Signals activated by various pathogens are integrated by IRF-3 kinase, resulting in the specific phosphorylation of IRF-3 in the cytoplasm. This phosphorylation
