FIG. 3.

Nucleotide sequence of the R3 region and the U95 promoter of HHV-6B strain HST. Numbers with “nt” indicate genome coordinates of HST, and numbers by the arrows indicate the 5′ deletion points of the U95 promoter constructs relative to the transcription start site (+1 asterisk). The R3 region sequence is shaded, and 9 putative binding sites for NF-κB (white background), 20 sites for PEA3 (underlined), and 10 KpnI recognition sites (white letters in black box) are indicated. Potential TATA motifs, which lie at positions −27 to −20 and −39 to −34 relative to the transcription start site, are boxed. Lowercase letters indicate spliced-out region, and boldface letters indicate consensus splice donor and acceptor sequences.
