Bayesian phylogenetic analysis of thioester proteins. Clades I–IV represent (I) an Anopheles gambiae specific species-expansion, (II) all genes except D. melanogaster TEP-5 have a TE motif (III) alpha-2-macroglobulin-like genes and (IV) genes lacking a thioester motif (TE). Those genes that have been functionally characterized to play a role in the immune system are highlighted in bold text. Branch numbers are posterior probabilities.
