Domain B has been described as a B-cell-specific EB1 -responsive element ( P . M . Lieberman , J . M . Hardwick , and S . D . Hayward , J . Virol . 63 : 3040-3050 , 1989 ) activated synergistically by EB1 and R , an EBV early product encoded by the open reading frame BRLF1 ( M . A . Cox , J . Leahy , and J . M . Hardwick , J . Virol . 64 : 313-321 , 1990 ) .
