Figure 3.

Sequence alignments of homeodomains and flanking sequences encoded by LsHox genes (Upper) plus caudal/Cdx and NK-1 orthologs (Lower). Dashes indicate amino acid identity between domains encoded by L. sanguineus homeobox genes and the most similar sequences from other phyla. Percentages indicated correspond to sequence identities within the homeodomain between L. sanguineus genes and the sequences from other phyla. The sequence comparison is limited to the small number of homeodomains known in protostomes for which complete sequence data are available.
