Previous Symbols for IRF4 Gene
The protein encoded by this gene belongs to the IRF (interferon regulatory factor) family of transcription factors, characterized by an unique tryptophan pentad repeat DNA-binding domain. The IRFs are important in the regulation of interferons in response to infection by virus, and in the regulation of interferon-inducible genes. This family member is lymphocyte specific and negatively regulates Toll-like-receptor (TLR) signaling that is central to the activation of innate and adaptive immune systems. A chromosomal translocation involving this gene and the IgH locus, t(6;14)(p25;q32), may be a cause of multiple myeloma. Alternatively spliced transcript variants have been found for this gene.

GeneCards Summary for IRF4 Gene
IRF4 (Interferon Regulatory Factor 4) is a Protein Coding gene. Diseases associated with IRF4 include primary cutaneous diffuse large b-cell lymphoma, leg type and primary cutaneous anaplastic large cell lymphoma. Among its related pathways are IL4-mediated signaling events and Interferon Signaling. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and transcription factor binding. An important paralog of this gene is IRF3.
UniProtKB/Swiss-Prot for IRF4 Gene
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. Involved in CD8(+) dendritic cell differentiation by forming a complex with the BATF-JUNB heterodimer in immune cells, leading to recognition of AICE sequence (5-TGAnTCA/GAAA-3), an immune-specific regulatory element, followed by cooperative binding of BATF and IRF4 and activation of genes (By similarity).
