The Viral Interferon Regulatory Factors of KSHV: Immunosuppressors or Oncogenes?
Kaposi's sarcoma-associated herpesvirus (KSHV) is a large double-stranded DNA gammaherpesvirus, and the etiological agent for three human malignancies: Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. To establish and maintain infection, KSHV has evolved unique mechanisms to evade the host immune response. Cellular interferon regulatory factors (IRFs) are a cri...
متن کاملIRF4 (interferon regulatory factor 4)
Other names: IRF-4; NF-EM5; LSIRF (lymphocytespecific interferon regulatory factor); MUM1 (multiple myeloma oncogene 1) HGNC (Hugo): IRF4 Location: 6p25.3 Local order: IRF4 is located on chromosome 6 at the telomeric extremity of the short arm, and lies between the DUSP22 (dual specificity phosphatase 22) and EXOC2 (exocyst complex component 2) genes. Note: IRF4 belongs to the IRF (interferon r...
متن کاملDifferential viral induction of distinct interferon-alpha genes by positive feedback through interferon regulatory factor-7.
Interferon (IFN) genes are among the earliest transcriptional responses to virus infection of mammalian cells. Although the regulation of the IFNbeta gene has been well characterized, the induction of the large family of IFNalpha genes has remained obscure. We report that the IFNalpha genes can be divided into two groups: an immediate-early response gene (IFNalpha4) which is induced rapidly and...
متن کاملInterferon Regulatory Factor 4 (IRF4) Interacts with NFATc2 to Modulate Interleukin 4 Gene Expression
Proteins of the nuclear factor of activated T cells (NFAT) family of transcription factors are critical for lymphocyte activation in the immune system. In particular, NFATs are important regulators of inducible IL-4 gene expression. Interferon regulatory factor 4 (IRF4) is an immune system-restricted interferon regulatory factor that is required for lymphocyte activation, but its molecular func...
متن کاملViral interferon regulatory factor 1 of Kaposi's sarcoma-associated herpesvirus interacts with a cell death regulator, GRIM19, and inhibits interferon/retinoic acid-induced cell death.
Kaposi's sarcoma-associated herpesvirus (KSHV) plays a significant role in the development of Kaposi's sarcoma, primary effusion lymphoma, and some forms of multicentric Castleman's disease. The KSHV open reading frame K9 encodes the viral interferon (IFN) factor 1 (vIRF1), which downregulates IFN- and IRF-mediated transcriptional activation, and leads to cellular transformation in rodent fibro...
