In the fruit fly Drosophila, odorant-binding proteins are secreted into the fluid that bathes olfactory neurons. Laughlin et al. (2008) now challenge the assumption that the odorant-binding protein LUSH passively transports its pheromone to a specific olfactory receptor. Instead, LUSH undergoes a conformational change upon pheromone binding that is sufficient for neuronal activation.
在果蝇中,气味结合蛋白被分泌到包围嗅觉神经元的液体中。劳克林等人(2008年)现在对气味结合蛋白LUSH被动地将其信息素转运至特定嗅觉受体这一假设提出了质疑。相反,LUSH在结合信息素后会发生构象变化,这种变化足以激活神经元。
