a SEM image of a skeletal element isolated from the feather star (A. japonica). b Proteins present in the feather star skeletal proteome were isolated from adult skeleton and identified by comparison of LC/MS/MS data to the genes computationally identified in the feather star genome. These proteins were compared to those found in skeletal proteomes of the sea urchin S. purpuratus62,63,64, the sea star P. miniata36 and the brittle star O. spicullata35. The most prevalent proteins are shown in the figure, along with the number of different proteins from the listed groups present in each species’ proteome. The feather star skeletal proteome contains members of each of the protein families shown. The other echinoderm species are missing some of these proteins in their skeletal proteome and the number of members in each protein family varies between groups.
