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). Structurally similar to other IRF family members, IRF-2 acts as both a transcription activator and repressor. IRF-2 promotes transcription of several genes, including histone H4, the VCAM1 cell adhesion protein, and CIITA, a MHC transactivator protein. Conversely, IRF-2 competitively binds to promoter sites utilized by IRF-1, repressing activation by this related transcription factor (3). Its activity may be controlled by inducible proteolysis (4). IRF-2 has also been associated with increased oncogenic potential (5,6) and lymphocyte development (7,8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDKFZp686F0244; Interferon regulatory factor 2; IRF-2; IRF2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 45\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799705112745,"sku":"4943S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-4943s","provider":"Iright","version":"1.0","type":"link"}
