The Epstein-Barr virus DR promoter is located upstream of the PstI repeats , and in addition to the TATA box , it contains an upstream region ( positions -69 to -220 ) responsive to EB1 ( Z ) ( the BZLF1-encoded transcription factor ) and an enhancer with two functionally distinct domains , A and B .
