Figure 1.
Amino acid comparison of the C-terminal regions of human TCF-4 and TCF-3. Amino acid identities are indicated by corresponding letters; amino acid similarities are indicated by double dots (closely related residues) or single dots (distantly related residues). Sequences were aligned with CLUSTALW. Overlining indicates highly conserved HMG box sequences; two putative CtBP binding sites are boxed. The arrows depict the amino acid sequence used in a yeast two-hybrid screen.
