Using protein-DNA interaction assays we show that the H4 promoter contains two ATF/ CREB recognition motifs which interact with CREB , ATF1 , and ATF2 but not with ATF4/CREB2 .
 ( DNA: H4 promoter, None) , ( protein: ATF2, None) , ( protein: ATF1, None) , ( protein: CREB, None) , ( protein: ATF4/CREB2, None) , ( protein: CREB, None)
