  • Function
    Signal transducer and activator of transcription that mediates signaling by type I IFNs (IFN-alpha and IFN-beta). Following type I IFN binding to cell surface receptors, Jak kinases (TYK2 and JAK1) are activated, leading to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize, associate with ISGF3G/IRF-9 to form a complex termed ISGF3 transcription factor, that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of interferon stimulated genes, which drive the cell in an antiviral state.
  • Sequence similarities
    Belongs to the transcription factor STAT family.
    Contains 1 SH2 domain.
  • Post-translational
    Tyrosine phosphorylated in response to IFN-alpha.
  • Cellular localization
    Cytoplasm. Nucleus. Translocated into the nucleus upon activation by IFN-alpha/beta.
