CC -!- FUNCTION: Gustducin-coupled receptor implicated in the perception of
CC bitter compounds in the oral cavity and the gastrointestinal tract.
CC Signals through PLCB2 and the calcium-regulated cation channel TRPM5.
CC {ECO:0000269|PubMed:10761934, ECO:0000269|PubMed:10761935}.
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
CC -!- TISSUE SPECIFICITY: Expressed in subsets of taste receptor cells of the
CC tongue and palate epithelium and exclusively in gustducin-positive
CC cells. Expressed in the antrum and fundus (part of the stomach),
CC duodenum and in gastric endocrine cells. {ECO:0000269|PubMed:10761934}.
CC -!- MISCELLANEOUS: Several bitter taste receptors are expressed in a single
CC taste receptor cell.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor T2R family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAU21157.1; Type=Erroneous initiation; Evidence={ECO:0000305};
