The duck βA-globin (βAGLB) enhancer was closely linked to the duck βA-GLB promoter, and the construct was used to study binding of nuclear proteins to specific sites of these regulatory elements. DNaseI-footprint analysis showed that the presence of the enhancer induced binding of proteins to additional sites on the promoter. The results are consistent with the looping-out model, based on specific interactions of enhancer-bound and promoter bound-proteins.
