  • 功能：
    Gustatory receptor required for response to the sugar trehalose in taste neurons. Gr5a neurons selectively respond to sugars, in contrast to Gr66a cells which respond to bitter compounds. Flies are attracted to sugars and avoid bitter substances, suggesting that Gr5a neuron activity is sufficient to mediate acceptance behavior. Sugar signal transduction occurs through coupling with G-proteins such as Galpha49B and G-salpha60A.

    7. Gustator receptors would be candidate sugar receptors because Gr5a-expressing cells function in the responses to attractive tastants. PMID: 17715294
    8. The simplest interpretation of our results is that Gr5a and Gr64a are each capable of functioning independently of each other within individual sugar neurons and that they are the primary receptors used in the labellum to detect sugars. PMID: 17988633
