MOESM3 of Genomic analysis of the tryptome reveals molecular mechanisms of gland cell evolution

Additional file 3. Human trypsin domain architecture mapped on the animal trypsin phylogeny. Proteins with multiple trypsin domains are polyphyletic; in such cases, the diagram points to a single trypsin domain and the position of the other trypsin domains is indicated by symbols. N. vectensis proteins characterized by in situ hybridization are indicated by arrows (this study), †[34], or *[12].
