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 -!- 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 duodenum, antrum and fundus (part of the
CC stomach). {ECO:0000269|PubMed:11854532}.
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}.
