We have shown that the Z gene product , which binds to AP-1 sites as a homodimer and has sequence similarity to c-Fos , can efficiently activate the EBV early promoter , BMRF1 , in certain cell types (i.e., HeLa cells ) but not others (i.e., Jurkat cells ).
 protein: Z gene product; DNA: BMRF1; DNA: AP-1 sites; protein: homodimer; DNA: EBV early promoter; DNA: c-Fos; cell line: HeLa cells; cell line: Jurkat cells
