    HOMOLOGY
    interspecies homolog to murine Isfg3g
    homolog to C.elegans R119.2
    intraspecies homolog to interferon regulatory factor and Myb family member of DNA binding proteins,highly

    FAMILY
  • IRF family
  • CATEGORY regulatory , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,cytosolic
    intracellular,nucleus,nucleoplasm
    text cytoplasmic but translocated to the nucleus after activation
    basic FUNCTION
  • acting as the DNA recognition subunit
  • activating transcription in response to alpha interferon
  • is the key factor for eliciting the antiproliferative activity of IFN-alpha
  • inhibits the development of cardiac hypertrophy by suppressing the transcriptional activity of myocardin in the heart
  • CELLULAR PROCESS nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    cell surface receptor linked signal transduction
    a component
  • component of interferon stimulated transcription factor 3 gamma
  • STAT1, STAT2 associates with IFN regulatory factor 9 (IRF9) to form a heterotrimeric transcription factor complex known as ISGF3
  • INTERACTION
    DNA binding to interferon-stimulated response element (or ISRE)
    RNA
    small molecule
    protein
  • nuclear transit of the intracellular domain of the interferon receptor subunit IFNAR2 requires STAT2 and IRF9
  • IRF1 and IRF9 are sequentially activated and recruited to the IL27 IFN-stimulated regulatory element site
  • interaction between STAT2 and IRF9
  • IFNB1-induced necroptosis of macrophages proceeds through tonic IFN-stimulated gene factor 3 (IRF9) signaling, which leads to persistent expression of STAT1, STAT2, and IRF9
  • IFNB1 signal may up-regulate CD274 expression through IRF9-dependent and independent pathways in lung cancer cells
