Insect chemosensory proteins.

Key Words：insect, chemosensory protein, structure, function

Abstract：Insect chemosensory proteins  expressed in various insect species have hydrophobic property. They have been supposed to transport nonvolatile chemicals to receptors on sensory neurons.   In this paper,  the knowledge of insect chemosensory proteins, including the sequence character, secondary and tertiary structural properties, affinity to ligands, expression pattern, physiology function and phylogenetic position, was presented. The research prospect and emphasis  based on new development of chemosensory proteins in insect were also  discussed.
