Fig. 1. Sequence comparisons of Lytechinus Snail and related Snail family proteins. (A) The zinc finger region of Lytechinus Snail compared with related proteins in other organisms. Positions of zinc-finger II-V are shown and the conserved cysteines and histidines are indicated with asterisks. (B) The SNAG domain of Lytechinus Snail fits the consensus and is identical to those of several other snail family members, including Acropora Snail and mouse Slug and Scratch. (C) Rooted neighbor-joining tree showing the relationship of Lytechinus Snail with other snail family proteins (1000 bootstraps, values indicated on nodes). Mouse and Drosophila Scratch served as outgroups.
