The senses of olfaction and gustation are essential chemosensory systems to recognize the tens of thousands of chemical compounds in nature. The genes of olfactory receptors (ORs) encode the large a large family of seven-transmembrane-domain G protein coupled receptors (GPCRs). However insect ORs possess the seven transmembrane topology with the intracellular amino terminus, and comprise the odor-gated ion channels (fig. 1). We focus on the molecular mechanism of signal transduction in chemical senses, which enable the complex neuronal coding of multiple of chemical information.
