Using the Dazl RRM domain, we searched for Dazl homologs in
the genomes of acorn worm from Hemichordata (Saccoglossus kowalevskii), sea urchin from Echinodermata (Strongylocentrotus purpuratus), lancelet from Cephalochordata (Branchiostoma floridae), and sea squirt from Tunicata (Ciona intestinalis).
