Membrane receptor signaling by various ligands induces activation of Jak kinases which then leads to tyrosine phosphorylation of the various Stat transcription factors. Stat1 and Stat2 are induced by IFN- and form a heterodimer which is part of the ISGF3 transcription factor complex. Although early reports indicate Stat3 activation by EGF and IL-6，it has been shown that Stat3B appears to be activated by both while Stat3 is activated by EGF，but not by IL-6. Highest expression of Stat4 is seen in testis and myeloid cells. IL-12 has been identified as an activator of Stat4. Stat5 is activated by prolactin and by IL-3. Stat6 is involved in IL-4 activated signaling pathways.
應用類型
Western blotting （1-4 ug/ml）. However， the optimal concentrations should be determined individually. The antibody recognizes ~113 kDa phosphorylated Stat2 （Tyr689） of human and mouse origins. Reactivity to other species has not been tested.
