Target Information
STAT4 was originally identified using degenerate primers complementary to sequences encoding conserved regions of other STAT proteins. The STAT4 protein shows similarity to STAT1 (52%) and STAT3 (47%). It 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. It is activated by interleukin 12 (IL-12), which is essential for IFN-gamma induction and Th1 response development, aiding host defense against intracellular pathogens. STAT4-deficient mice show impaired Th1 development and enhanced Th2 differentiation. In viral infection, IFN-a/b activation of STAT4 is required for IFN-gamma production.
