Abstract

We have previously shown that the Epstein-Barr virus (EBV) immediate-early gene product, BZLF1, can activate expression of the EBV BMLF1 immediate-early promoter in EBV-positive, but not EBV-negative, B cells, suggesting that the BZLF1 effect may be mediated through another EBV gene product (S. Kenney, J. Kamine, E. Holley-Guthrie, J.-C. Lin, E.-C. Mar, and J. S. Pagano, J. Virol. 63:1729-1736, 1989). Here, we show that the EBV BRLF1 immediate-early gene product transactivates the BMLF1 promoter in either EBV-positive or EBV-negative B cells. Deletional analysis revealed that both the BZLF1-responsive region and the BRLF1-responsive region of the BMLF1 promoter are contained within the same 140-base-pair FokI-PvuII fragment located 300 base pairs upstream of the mRNA start site. This FokI-PvuII fragment functions as an enhancer element in the presence of the BRLF1 transactivator and contains the sequence CCGTGGAGA ATGTC, which is strikingly similar to the BRLF1-responsive region of the EBV DR/DL enhancer (A. Chevallier-Greco, H. Gruffat, E. Manet, A. Calender, and A. Sergeant, J. Virol. 63:615-623, 1989). The effect of BZLF1 on the BMLF1 promoter is likely to be indirect and mediated through the BRLF1 transactivator.
