Deletion mapping and hybrid promoter constructs demonstrate that the newly identified Tat -responsive element corresponds to a sequence within the viral long terminal repeat ( LTR ) previously identified as the HIV-1 enhancer , or NF-kappa B domain .
 protein: Tat; DNA: HIV-1 enhancer; DNA: Tat -responsive element; DNA: NF-kappa B domain; DNA: viral long terminal repeat; DNA: hybrid promoter constructs; DNA: LTR
