Nucleotide sequences of HBV between nt 1570 to 1771 including the EnII region. The underlined sequences represent Sp1, HNF1, HNF3, HNF4, and FTF (hB1F) recognition sequences, as labeled. Box α (nt 1645 to 1669) and box β (nt 1705 to 1716) in the CURS are shown in italics. The open box indicates the sequence from nt 1640 to 1663 which was used in gel retardation analysis. This region includes the extended C/EBP consensus sequence (T[T/G]NNG[C/T]AA[T/G]).
