Signal transducer and activator of transcription-2
Background
STAT2 (Signal transducer and activator of transcription 2) is JAK-STAT-family transcription factor specialized for type-I interferon (IFN-α/β) signal transduction. Following type-I-interferon receptor activation, JAK kinases phosphorylate STAT2 and STAT1. STAT1-STAT2 heterodimer associates with IRF9 to assemble ISGF3 complex, which translocates into nucleus and targets ISRE motifs to drive interferon-stimulated-gene transcription and establish cellular antiviral state. STAT2 is indispensable for type-I-IFN responses and dispensable for IFN-γ signalling. STAT2-deficient cells lose type-I-IFN-mediated antiviral protection.
