Protein-coding gene in the species Homo sapiens
Taste receptor type 2 member 3 is a protein that in humans is encoded by the TAS2R3 gene .[5]
Function [ edit ] This gene encodes a member of a family of candidate taste receptors that are members of the G protein-coupled receptor superfamily and that are specifically expressed by taste receptor cells of the tongue and palate epithelia. These apparently intronless taste receptor genes encode a 7-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered with another 3 candidate taste receptor genes in chromosome 7 and is genetically linked to loci that influence bitter perception.[5]
Ligands [ edit ] The only known ligand for TAS2R3 in BitterDB is chloroquine .[6]
