Fig. 4. (A) Nucleotide sequence of the 5'-flanking region of As-T2, including the regions for its muscle-specific (shown with red letters) and TT-specific (shown with blue letters) expression. A putative Gli protein-binding motif is shown with a yellow underline. The transcription start site is shown as +1, and eleven deduced amino acids are shown in the lower right-hand corner. The purple box indicates the Tp (proximal T-binding motif) and the green box indicates the Td (distal T-binding motif). (B) Suggested motifs and sequences responsible for the specific expression of As-T2. (C) Sequences of T protein-binding motifs shared by various T-related genes. Dots indicate conserved nucleotides.
