Thus, we propose that GATA-3 is permissive, but not sufficient, for full IL-4 enhancement and may act through GATA elements surrounding the IL-13 / IL-4 gene locus .
 ( DNA: IL-4 gene, None) , ( protein: IL-4, None) , ( DNA: IL-13 / IL-4 gene locus, None) , ( protein: IL-13, None) , ( protein: GATA-3, None) , ( protein: IL-4, None) , ( DNA: GATA elements, None)
