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       (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
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}.
