Data obtained by electrophoretic mobility shift assay suggested that the activated Stat-3 protein associates with the human serum-inducible element ( hSIE ) DNA-probe derived from the interferon-gamma activated site ( GAS ) in the c-fos promoter , a common DNA sequence for Stat protein binding .
 ( DNA: interferon-gamma activated site, None) , ( DNA: hSIE, None) , ( DNA: c-fos promoter, None) , ( DNA: human serum-inducible element ( hSIE ) DNA-probe, None) , ( protein: activated Stat-3 protein, None) , ( protein: Stat protein, None) , ( DNA: GAS, None)
