Simplified phylogenetic tree of metazoan (sub)phyla. Only the (sub)phyla that hold more than 1000 nucleotide or EST sequences according to the NCBI taxonomy platform were taken into account. The (sub) phyla, in which pacifastin-related members were predicted, are highlighted. A question mark is used when the origin of the (sub) phylum is uncertain.
