Background of IRF3 antibody

Interferon regulatory factors (IRFs) comprise a family of transcription factors that function within the Jak/Stat pathway to regulate interferon (IFN) and IFN-inducible gene expression in response to viral infection. IRFs play an important role in pathogen defense, autoimmunity, lymphocyte development, cell growth, and susceptibility to transformation. The IRF family includes nine members: IRF-1, IRF-2, ISGF3?/p48, IRF-3, IRF-4 (Pip/LSIRF/ICSAT), IRF-5, IRF-6, IRF-7, and IRF-8/ICSBP. All IRF proteins share homology in their amino-termil D-binding domains. IRF family members regulate transcription through interactions with proteins that share similar D-binding motifs, such as IFN-stimulated response elements (ISRE), IFN consensus sequences (ICS), and IFN regulatory elements (IRF-E).IRF-3 can inhibit cell growth and plays a critical role in controlling the expression of genes in the inte 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-termil Ser and Thr residues (between 385 and 405), leading to its association with the p300/CBP coactivator protein that promotes D binding and transcriptiol activity. During infection, IRF-3 is likely activated through a pathway that includes activation of Toll-like receptors and a kise complex that includes IKKe and TBK1. IRF-3 is phosphorylated at Ser396 following viral infection, expression of viral nucleocapsid, and double-stranded R treatment. These events likely play a role in activation of IRF-3.
