The repressor activity of the 5'-UTR was localized to tandem GATA-like sites , which appear to bind a complex of two proteins, one of which is the erythroid transcription factor GATA-1 .
 ( DNA: 5#$%#-UTR, None) , ( protein: transcription factor, None) , ( protein: GATA-1, None) , ( protein: erythroid transcription factor, None) , ( DNA: GATA-like sites, None)
