Description
Description

The Gustatory receptors are a divergent group of (non-GPCR) seven-transmembrane chemoreceptors that are expressed in gustatory sensilla receptor neurons. They detect tastants (non-volatile compounds) via contact chemosensation. (Adapted from FBrf0208984).

Notes on Group

The roles of the gustatory receptors go beyond peripheral detection of non-volatile chemicals. For example, it was shown that Gr28b is required for thermotaxis, Gr43a serves as a nutrient sensor, Gr21a and Gr63a act in the detection of CO2. (FBrf0223100).
