Chemosensory proteins diversity

The odorant-binding proteins (OBPs) and the chemosensory proteins (CSPs) are proteins from the lymph that are thought to accomplish these tasks, solubilizing and protecting the odorant and contact chemosensory molecules. This chapter describes the biochemical and evolutionary aspects of these two families of peripheral sensory proteins of insects. Particular attention will be paid to the subclassification of binding proteins, the diversity of gene structures and the phyletic and molecular relatedness between binding proteins from different insect species.
