Rather, hEpoR transcription activity depends on coordination between Sp1 and GATA-1 with other cell-specific factors , including possibly other Sp1 -like binding proteins , to provide high level, tissue-specific expression .
 ( protein: hEpoR, None) , ( protein: Sp1, None) , ( protein: cell-specific factors, None) , ( protein: Sp1, None) , ( protein: GATA-1, None) , ( protein: Sp1 -like binding proteins, None)
