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). In airway epithelial cells, binding of denatonium
CC       increases the intracellular calcium ion concentration and stimulates
CC       ciliary beat frequency (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. Cell
CC       projection, cilium membrane. Note=In airway epithelial cells, localizes
CC       to motile cilia. {ECO:0000250}.
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}.
