21. This intronless taste receptor gene encodes a 7-transmembrane receptor protein, functioning as a bitter taste receptor . 22. Association between its taste and several other genes, including a bitter-taste receptor , have also been found. 23. These proteins are specifically expressed in the taste receptor cells of the tongue and palate epithelia. 24. The taste receptor TAS1R3 and the taste G protein gustducin are two of the most common. 25. This intronless taste receptor gene encodes a 7-transmembrane receptor protein, functioning as a bitter taste receptor. 26. These apparently intronless taste receptor genes encode a 7-transmembrane receptor protein, functioning as a bitter taste receptor . 27. Cats have no sweet taste receptors on their tongue and thus cannot taste sweet things at all. 28. These apparently intronless taste receptor genes encode a 7-transmembrane receptor protein, functioning as a bitter taste receptor. 29. They appear to be distantly related to the mammalian T2R bitter taste receptors and the rhodopsin-like GPCRs. 30. The bitter taste receptor family, T2R ( TAS2R ), is encoded on two chromosomes, 7 and 12.
