Target Information
STAT4 was originally identified using degenerate primers complementary to sequences encoding conserved regions of other STAT proteins. The STAT4 protein shares similarity with STAT1 (52%) and STAT3 (47%). Functionally, STAT4 can be tyrosine phosphorylated by Jak1 or Jak2, forming 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. It is activated by interleukin 12 (IL-12), which is essential for the T-cell independent induction of IFN-gamma and the development of Th1 responses necessary for defense against intracellular pathogens. STAT4-deficient mice exhibit impaired IL-12–mediated Th1 development and enhanced Th2 cell development. In viral infection, IFN-α/β activation of STAT4 is required for IFN-γ production.
