Figure 3From: Identification, distribution and molecular evolution of the pacifastin gene family in MetazoaGene structure (exons) of coleopteran, dipteran, hymenopteran, hemipteran and phthirapteran pacifastin-like genes. For each precursor (PP) gene, the exons are shown as roman numbers. The exons that encode the signal peptide and different PLD-related domains of the PP are illustrated by white and grey boxes. The PP indicated in bold are encoded by clustered genes.Back to article page
