Taste receptor type 2 member 4 is a protein that in humans is encoded by the TAS2R4 gene.[4][5][6]


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 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.[6]


Ligands listed in BitterDB include quinine, parthenolide, denatonium, some non-sugar sweeteners including sucralose and stevioside, and several oligopeptides.[7]
