Function
Receptor that may play a role in the perception of bitterness and is gustducin-linked. May play a role in sensing the chemical composition of the gastrointestinal content. The activity of this receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5.
Tissue Specificity Expressed in subsets of taste receptor cells of the tongue and palate epithelium and exclusively in gustducin-positive cells.
KEGG Pathway
Taste transduction (hsa04742 )
Reactome Pathway
Class C/3 (Metabotropic glutamate/pheromone receptors) (R-HSA-420499 )
Sensory perception of sweet, bitter, and umami (glutamate) taste (R-HSA-9717207 )
G alpha (i) signalling events (R-HSA-418594 )
