The SC component SC65 occurs not only in Deuterostomia (Table 6), but also, possibly, in Coelenterata, Porifera, and certain Protostomia as well (Table 5).
Multigene analyses of bilaterian animals corroborate the monophyly of ecdysozoa, lophotrochozoa, and protostomia. Mol Biol Evol.
We have recently conducted extensive analyses of aquaporins encoded in arthropod genomes (Finn et al., 2015; Stavang et al., 2015), and we have further screened the genomes of members of the Lophotrochozoa to provide a preliminary assessment of the diversity of aquaporins present in Protostomia. We have not found any ortholog that did not fall within the four-grade classification depicted in Figure 3.
Many sphingoglycolipids, other than those reported in this study, have been identified in protostomia. 43) Some of them, or yet unveiled glycolipids, may share biologically or neurobiologically important functions proposed for gangliosides in vertebrates.
Deuterostomia is a super phylum that encompasses hemichordates (Enteropneusta), echinoderms (sea urchins), and chordates (vertebrates); along with the phylum protostomia, it represents all animals having bilateral symmetry at least early in development (Fig.
