Evolutionary features of thyropins in arthropods. (A) Phylogenetic tree using the selected thyropin sequences from the different arthropod species. Coloured triangles show thyropin gene proliferations associated to other protein domains. In brackets the number of proteins in each subtree. (B) Presence (+) or absence (−) of thyropins members of each subtree in the different arthropod species. WAP, whey acidic protein; ATN, antistasin; SPARC, secreted protein acidic and rich in cysteine.
