CSC-CTK0186
Description
IRF-4 is a transcriptional activator, belonging to the IRF family. It binds to the interferon- stimulated response element (ISRE) of the MHC Class I promoter (but is not induced by Interferons). IRF-4 binds the immunoglobulin lambda light chain enhancer, together with Pu.1. It most likely plays a role in ISRE-targeted signal transduction mechanisms specific to lymphoid cells. IRF-4 / MUM-1 is expressed in the nuclei and cytoplasm of plasma cells and a small percentage of germinal center (GC) B cells mainly located in the "light zone". Its morphologic spectrum ranged from that of centrocyte to that of a plasmablast/plasma cell, and it displayed a phenotype (MUM-1+/Bcl-6/Ki67 ) different from that of most GC B cells (MUM-1 /Bcl-6+/Ki67+) and mantle B cells (MUM-1 /Bcl-6 /Ki67). Human recombinant IRF-4 (aa 144-451) expressed in E. coli is fused to a GST-tag and purified by proprietary chromatographic techniques.
