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, IRF-9\/ISGF3γ, 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-terminal DNA-binding domains. IRF family members regulate transcription through interactions with proteins that share similar DNA-binding motifs, such as IFN-stimulated response elements (ISRE), IFN consensus sequences (ICS), and IFN regulatory elements (IRF-E) (2). IRF-3 can inhibit cell growth and plays a critical role in controlling the expression of genes in the innate immune response (1-4). 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 carboxyl-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 (5). During infection, IRF-3 is likely activated through a pathway that includes activation of Toll-like receptors and of a kinase complex that includes IKKε and TBK1 (6,7). IRF-3 is phosphorylated at Ser396 following viral infection, expression of viral nucleocapsid, and double stranded RNA treatment. These events likely play a role in activation of IRF-3 (8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nC920001K05Rik; Interferon regulatory factor 3; IRF; IRF-3; Irf3; MGC91046; OTTMUSP00000022256; OTTMUSP00000022257; OTTMUSP00000022258\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: M\nSENSITIVITY: Endogenous\nMW (kDa): 45\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800126214313,"sku":"79945T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-79945t","provider":"Iright","version":"1.0","type":"link"}
