Target Information
STAT4 was originally identified using degenerate primers complementary to sequences encoding conserved regions of other STAT proteins. The STAT4 protein shares 52% similarity with STAT1 and 47% with STAT3. Functionally, STAT4 can be tyrosine phosphorylated by Jak1 or Jak2 and forms homo- and heterodimers with related STAT family members.
Tyrosine phosphorylated STAT4 binds the IFN-gamma activated site (GAS), and serine phosphorylation is required for maximal transcriptional activity. STAT4 expression is restricted to the thymus, spleen, and testis.
STAT4 is activated by the cytokine interleukin 12 (IL-12), which induces IFN-gamma production and promotes Th1 cell development essential for defense against intracellular pathogens. STAT4-deficient mice show impaired Th1 development and enhanced Th2 response. Additionally, IFN-α/β activation of STAT4 is required for IFN-γ production during viral infection.
