Phylogenetic relationship between the IDA/IDL and PIP/PIPL peptides. (A) Sequence logo representation of the conserved C-terminal of IDA/IDL, PIP/PIPL and CEP peptides. (B) N-J and ML trees were constructed based on the protein alignment of the IDA/IDL and PIP/PIPL families shown in Fig. 1A. The N-J trees are shown. The overall topologies for the N-J and ML trees are the same. Bootstrap confidence values above 50% for N-J (first value) and ML (second value) are shown in the tree.
