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.

Specificity

This antibody recognizes IRF-3 phosphorylated at Ser396.

Immunogen

Epitope: SNS → ANA: Mutation of this residue results in loss of viral-induced phosphorylation of IRF-3.
KLH-conjugated linear peptide corresponding to human IRF-3 phosphorylated at Ser396.
