Phylogenetic analysis of Schmidtea calreticulin and homologues from selected species. We identified a calreticulin protein in the Schmidtea cDNA library. Using corresponding EST sequence and further EST sequences from the public database (DN316126 and EG417940) we constructed the potential full-length protein. A Bayesian protein tree was generated using calreticulin sequences from Schmidtea and from selected species (Trypanosoma cruzi, EAN82340; Leishmania infantum, XP_001467584; Dictyostelium discoideum, XP_639010; Eisenia fetida, ABI74618; Schistosoma japonicum, ABK34456; Taenia solium, AAK52725; Echinococcus granulosus, AAX73173; Apis mellifera, XP_392689; Drosophila melanogaster, NP_524293; Tribolium castaneum, XP_971763; Crassostrea gigas, BAF63639; Onchocerca volvulus, AAA59056; Necator americanus, CAA07254; Heligmosomoides polygyrus, CAL30086; Caenorhabditis elegans, NP_504575; Ixodes scapularis, AAT99573; Homo sapiens, NP_004334; Strongylocentrotus purpuratus, NP_999643). As outgroup we selected plant Arabidopsis thaliana calreticulin (NP_001031199). This phylogenetic analysis reveal that calreticulins are evolutionarily conserved and that Schmidtea calreticulin (indicated by gray shading) form an own group with calreticulins from parasitic Platyhelminthes. The scale bar represents the substitutions per site.
