In DNA-protein binding studies , we detected the binding of transcription factors GABP alpha and -beta to a dyad symmetry element ( DSE ) of the distal enhancer , which is formed by palindromic binding sites of Ets-like factors .
 DNA: DSE; protein: transcription factors; DNA: dyad symmetry element; DNA: palindromic binding sites; protein: Ets-like factors; DNA: distal enhancer
