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}.
