Fig. 2. Structures of ANTP. (A) An alignment of amino acid sequences around YPWM motifs and homeodomains (blocked) of DapANTP (DDBJ Accession Number, AB069680) and DmANTP (cDNA G1100) (Laughon et al., 1986). Identical amino acid residues are indicated by asterisks and conserved ones by dots. Borders of N, HD and C regions are indicated. Amino acid sequences matching the consensus CKII phosphorylation sites are underlined and diagnostic amino acid residues are indicated in bold. (B) Structures of native and mutant ANTP constructs used in this study. Amino acid sequences derived from DapANTP are shown in pink and those from DmANTP in blue. Black bars, blocks and the open box indicate the YPWM motifs, homeodomains and the homology found in several insects, respectively. Asterisks indicate putative CKII sites in the CDm.
