An unknown background band is detected at 80 kDa in some cell lines. Species Reactivity: Human, Mouse Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly65 of human IRF-8 protein. Background 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 (1). 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-8/ICSBP is expressed predominantly in hematopoietic cells and is further increased upon treatment with interferon (3,4). IRF-8 can function as a transcription repressor of ICS-containing promoters (4). IRF-8 expression can lead to downregulation of the anti-apoptotic protein Bcl-2 (5). Originally described as being induced by IFN-γ, IRF-8 expression is also elevated by IRF-α as well as IL-12 in NK and T cells (6). IRF-8 deficient mice have enhanced susceptibility to various pathogens, impaired interferon production, and deregulated hematopoiesis resembling chronic myelogenous leukemia (7,8). IRF-8 also regulates bone metabolism by suppressing osteoclast formation (9).
