UniProt Summary: Gustducin-coupled receptor for denatonium and N(6)- propyl-2-thiouracil implicated in the perception of bitter compounds in the oral cavity and the gastrointestinal tract. Signals through PLCB2 and the calcium-regulated cation channel TRPM5. In airway epithelial cells, binding of denatonium increases the intracellular calcium ion concentration and stimulates ciliary beat frequency. {ECO:0000269|PubMed:19628819}.
