Phylogenetic analysis of the full protein sequences of CPAP3s from ten different insect species; Acyrthosiphun pisum (Ap), Aedes aegypti (Aa), Anopheles gambiae (Ag), Apis mellijera (Am), Culex quinquefasdatus (Cq), Drosophila melanogaster (Dm), M. sexta (Ms), Nasonia vitripennis (Np), Pediculus humanus corporis (Phc), Tribolium castaneum (Tc). The accession numbers of all the proteins used are listed in Supplementary Table 1. CPAP3s are grouped into seven different groups; group A1 (dark blue), groups A2 (light blue), group B (orange), group C (yellow), group D1 (dark purple), group D2 (light purple) and group E (green). CPAP3s from M. sexta are indicated in bold. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
