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 .
