Figure 9.

(A) The amino acid sequences of the Tax(224-243) region from HTLVs and STLVs. The amino acids of Tax from the other six viruses identical to that of Tax1 are indicated by a bar. The leucine residues constituting a putative LZ structure are surrounded by a circle. The amino acid sequences were obtained from a previous study [35]. (B) The amino acid sequences in the C-terminal ends of the respective Tax protein are shown. The PBMs are surrounded by squares.
