In addition to activating transcription from the viral long terminal repeat ( LTR ) through the cyclic AMP response element binding protein/activating transcription factor ( CREB/ATF ) family of transcription factors , Tax activates the expression of multiple cellular promoters through the NF-kappaB pathway of transcriptional activation .
