Figure 1. The CMPl protein family.

(A) Predicted amino-acid sequence of the P. lividus CMPl, with Compass- and Homeo- domain highlighted in green and yellow, respectively. (B) Comparison of the CMPl, CMP and SATB Homeodomains among various species. Differently coloured boxes highlight similarities; dashes represent the gaps inserted for maximal alignment; position 48 is marked by a filled circle, whereas the glycine insertion in SATB sequences is pointed by a triangle. (C) Rooted neighbor-joining tree constructed from the Homeodomains of representative CMPl, CMP and SATB family members. P. lividus sequence names are in red; numbers above nodes record percent bootstrap values, while asterisks indicate outgroups. Complete taxonomic names and accession numbers of all the sequences used to elaborate the tree are listed in Supplementary Table S1.
