    ..We found that all seven Grs most related to Gr5a (Gr64a-f and Gr61a) were expressed in Gr5a-expressing cells, whereas none of the other Grs examined were enriched in these Gr neurons ..
  3. Dahanukar A, Lei Y, Kwon J, Carlson J. Two Gr genes underlie sugar reception in Drosophila. Neuron. 2007;56:503-16 pubmed
    ..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. ..

    ..Thus, our studies indicate that the Gr43a-expressing brain neurons function as a nutrient sensor for hemolymph fructose and assign opposing valence to feeding experiences in a satiation-dependent manner. ..

    ..Furthermore, we employed this novel method to identify glucose as the primary ligand for the sugar receptor Gr61a, which is not only expressed in sweet sensing neurons of classical chemosensory sensilla, but also in two ..
