Competition EMS analyses utilizing Sp1 and CREB binding site oligonucleotides demonstrate that Sp family members are critical components of U1 ( U1A/U1B ) and U2 and that ATF/CREB family members are critical components of C1-C3 .
 ( protein: ATF/CREB family members, None) , ( DNA: U1, None) , ( DNA: U1A/U1B, None) , ( protein: Sp family members, None) , ( DNA: C1-C3, None) , ( DNA: U2, None)
