| Research Abstract |
To elucidate molecular mechanisms underlying highly sensitive detection of sex pheromones in insects, we examined functional roles of sex pheromone receptor proteins, pheromone binding proteins, and sensory neuron membrane protein-1 (SNMP1) in the silkmoth Bombyx mori. We found that the response specificity of pheromone receptor neurons is determined by the response spectrum of the expressed receptor protein. We also found that expression of SNMP1 increases the peak response amplitude of Xenopus oocytes expressing pheromone receptor proteins to pheromone stimulations.
