Fig. 1.

Phylogenetic analysis of Uncx proteins in metazoans. Numbers at branches represent replicates obtained using the Maximum Likelihood estimation method. The complete protein sequences were employed for tree inference. Uncx proteins deriving from teleost-specific genome duplication (TSGD) are shown in red. Protostome and Ambulacrarian Uncx proteins are grouped in the blue and green triangle, respectively. All sequences used in this analysis are reported in the Suppl. File 1. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
