Taste receptor, type 2, member 9
This gene product belongs to the family of candidate taste receptors that are members of the G-protein-coupled receptor superfamily. These proteins are specifically expressed in the taste receptor cells of the tongue and palate epithelia. They are organized in the genome in clusters and are genetically linked to loci that influence bitter perception in mice and humans. In functional expression studies, they respond to bitter tastants. This gene maps to the taste receptor gene cluster on chromosome 12p13. [provided by RefSeq, Jul 2008] (from

Likewise, single nucleotide polymorphisms (SNPs) shown previously to explain variation in the suprathreshold bitterness of AceK (rs3741845 in TAS2R9 and rs10772423 in TAS2R31) did not explain variation in RebA and RebD bitterness.

For 7 genes for bitter taste (TAS2R1, TAS2R3, TAS2R7, TAS2R9, TAS2R10, TAS2R16, and TAS2R38) and for 3 genes for fat taste (GPR40, GPR43, and GPR120), a full homology for exon sequences was found and primers were designed by Primer3.
