Finally, we show that a DNA fragment containing the human GATA3 transcription unit , 3 kb upstream from the initiation site and 4 kb downstream from the polyadenylation site , displays T-cell specificity .
 ( DNA: DNA fragment, None) , ( DNA: human GATA3 transcription unit, None) , ( DNA: 3 kb upstream, None) , ( DNA: initiation site, None) , ( DNA: 4 kb downstream, None) , ( protein: GATA3, None) , ( DNA: polyadenylation site, None)
