    摘要: The present disclosure relates generally to methods and materials for the identification of compounds that modulate (e.g., enhance, agonize, or antagonize) G protein-coupled receptor (GPCRs), such as those involved in taste. Examples of such GPCR include the TAS1R proteins and the TAS2R proteins that are involved in sensing sweet taste. In certain aspects, the disclosure provides cell-based and label-free assays that use highly sensitive biosensors to detect candidate taste modulator compounds by their alteration of GPCR activity. In some embodiments, such cell-based and label-free assays may be used to detect changes in cell mass distribution, cell adhesion, or cell morphology, resulting from contact with a candidate taste modulator compound. In some embodiments, such assays detect GPCR activation with greatly improved sensitivity compared to conventional assay methods.
