Strict dependence of HS I activity on a GATA site implies that assembly of a protein complex containing a GATA-factor , presumably GATA-1 or GATA-2 , is critical to activating or maintaining its function.
 ( protein: GATA-2, None) , ( protein: GATA-factor, None) , ( DNA: HS I, None) , ( DNA: GATA site, None) , ( protein: GATA-1, None)
