      Description Anti-IRF4 Antibody, NT
      Background Information Interferon regulatory factor 4, also known as IRF4, belongs to the IRF family. IRF4 encodes a 450 amino acid polypeptide with a predicted molecular weight of 51.6 kDa (Grossman 1996). The IRF4 gene is expressed in the spleen, lymphocytes and melanocytes, and is induced in to T cells after cross linking with the T cell receptor. IRF4 is a transcriptional activator that binds to the interferon stimulated response element (ISRE) of the MHC class I promoter. IRF4 is essential for mature T and B lymphocyte function. IRF4 interacts with MYD88 to prevent the interaction of IRF5, resulting in negative regulation of Toll Like Receptor (TLR) signaling. High levels of IRF4 have been associated with Epstein Barr Virus (EBV) and may be critical to EBV transformation. Further oncogenic potential has been associated with the involvement of IRF4 with hair color and pigmentation of the skin, which may cause multiple myeloma.

      UniProt Summary Function: Transcriptional activator. Binds to the interferon-stimulated response element (ISRE) of the MHC class I promoter. Binds the immunoglobulin lambda light chain enhancer, together with PU.1. Probably plays a role in ISRE-targeted signal transduction mechanisms specific to lymphoid cells.
      Subunit structure: Interacts with SPIB and DEF6. Ref.5 Ref.6
      Subcellular location: Nucleus.
      Tissue specificity: Lymphoid cells.
      Induction: Not induced by interferons.
      Involvement in disease: A chromosomal aberration involving IRF4 may be a cause of multiple myeloma [MIM:254500]. Translocation t(6;14)(p25;q32) with the IgH locus.
      Sequence similarities: Belongs to the IRF family.
      Contains 1 tryptophan pentad repeat DNA-binding domain.
