TAS2R50 belongs to the large TAS2R receptor family. TAS2Rs are expressed on the surface of taste receptor cells and mediate the perception of bitterness through a G protein-coupled second messenger pathway. 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. Expressed in subsets of taste receptor cells of the tongue and exclusively in gustducin-positive cells. Most taste cells may be activated by a limited number of bitter compounds; individual taste cells can discriminate among bitter stimuli.
