Fig 7. Divergence of a set of vascular proteins from human among 10 species.

We analyzed the 54 proteins that demonstrated lack of an orthologue in at least one species. For each species, we summed the number of genes without an orthologue with the number of genes with sequence similarity (versus human) under 70%. The graph displays the percentage of proteins which are predicted to be absent or highly divergent for each species listed. White bars show divergence of all proteins in the set of 54; black bars show divergence of the combination of EC/VSMC and VSMC-only proteins (32 of the 54 proteins).
