Taste receptor, type 2, member 4
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. [provided by RefSeq, Jul 2008] (from
Chelikani et al., Winnipeg, Canada. In Biochem Biophys Res Commun, 2014
In this report using quantitative (q)-PCR and flow cytometry, we characterized the expression of T2R1, T2R4, T2R10, T2R38 and T2R49 in the highly metastatic breast cancer cell line MDA-MB-231, poorly metastatic cell line MCF-7, and non-cancerous mammary epithelial cell line MCF-10A.

Transgenic Drosophila expressing human T2R4 and T2R38 bitter-taste receptors or PKD2L1 sour-taste receptor in the fly gustatory receptor neurons and other tissues were prepared using conventional Gal4/UAS binary system.

As a proof of the concept, we generated transgenic worms expressing human T2R4 or its mouse ortholog T2R8 receptors, which respond to two bitter tastants previously characterised as their functional ligands, 6-n-propyl-2-thiouracil and denatoniun.
