Members of the cyclic adenosine monophosphate ( cAMP ) response element binding (CREB)/activating transcription factor 1 ( ATF-1 ) family of transcription factors bind three 21-bp repeats ( Tax-responsive element-1 , or TRE-1 ) within the viral promoter and are important for basal and Tax-mediated transcription .
 DNA: cyclic adenosine monophosphate ( cAMP ) response element; DNA: viral promoter; protein: transcription factors; DNA: 21-bp repeats; protein: ATF-1; DNA: Tax-responsive element-1; protein: cyclic adenosine monophosphate ( cAMP ) response element binding (CREB)/activating transcription factor 1 ( ATF-1 ) family; DNA: TRE-1
