Furthermore , we have identified the major open reading frame ( RF4 ; 2 . 3 kb ) as being essential for activation , and we have shown that the NF kappa B , SP1 , and TATA box motifs in the human immunodeficiency virus LTR are all required for full induction of the promoter by the HHV - 6 - encoded transactivator .
