CC -!- FUNCTION: Receptor that may play a role in the perception of bitterness
CC and is gustducin-linked. May play a role in sensing the chemical
CC composition of the gastrointestinal content. The activity of this
CC receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation
CC and lead to the gating of TRPM5 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
CC -!- MISCELLANEOUS: Most taste cells may be activated by a limited number of
CC bitter compounds; individual taste cells can discriminate among bitter
CC stimuli.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor T2R family.
CC {ECO:0000305}.
