Fig. 5. The Cs-ttf1 gene product. (A) The predicted amino acid sequence. The homeodomain is underlined. (B) Alignment of amino acid sequence of the homeodomain of Cs-TTF1 protein with those of Ci-TTF1 (Ristoratore et al., 1999) and mouse TTF1 (Lazzaro et al., 1991). Identities of the amino acid residues are shown by asterisks and similarities by dots.
