Using a series of constructs containing deletions and mutations in this region, we found that the 3'-most site alone was sufficient for binding GA-binding protein alpha ( GABP alpha )/ GABP beta and for a low level of transcriptional activation .
 ( protein: GABP alpha )/ GABP beta, None) , ( protein: GABP beta, None) , ( DNA: 3#$%#-most site, None) , ( protein: GABP alpha, None) , ( protein: GA-binding protein alpha, None)
