The present invention relates to the discovery, identification and characterization of a transient receptor potential channel, referred to herein as TRP8, which is expressed in taste receptor cells and associated with the perception of bitter and sweet taste. The invention encompasses TRP8 nucleotides, host cell expression systems, TRP8 proteins, fusion proteins, polypeptides and peptides, antibodies to the TRP8 protein, transgenic animals that express a TRP8 transgene, and recombinant "knock-out" animals that do not express TRP8. The invention further relates to methods for identifying modulators of the TRP8-mediated taste response and the use of such modulators to either inhibit or promote the perception of bitterness or sweetness. The modulators of TRP8 activity may be used as flavor enhancers in foods, beverages and pharmaceuticals.

What is claimed: 1. A method for identifying a compound that modulates TRP8 activity, said method comprising: (i) contacting a cell expressing the TRP8 channel protein of SEQ ID NO: 4 with a test compound and a compound or molecular complex that results in TRP8 activation, and measuring the level o
What is claimed: 1. A method for identifying a compound that modulates TRP8 activity, said method comprising: (i) contacting a cell expressing the TRP8 channel protein of SEQ ID NO: 4 with a test compound and a compound or molecular complex that results in TRP8 activation, and measuring the level of TRP8 activation; (ii) in a separate experiment, contacting a cell expressing the TRP8 channel protein of SEQ ID NO: 4 with a compound or molecular complex that results in TRP8 activation and measuring the level of TRP8 activation, where the conditions are essentially the same as in part (i); and (iii) comparing the level of TRP8 activation measured in part (i) with the level of TRP8 activation measured in part (ii), wherein said measuring the level of TRP8 activation comprises measuring the membrane potential of the cell, and wherein a decrease in the level of TRP8 activation in the presence of the test compound indicates that the test compound is a TRP8 inhibitor, and an increase in the level of TRP8 activation in the presence of the test compound indicates that the test compound is a TRP8 activator. 2. The method according to claim 1, wherein said measuring the level of TRP8 activation is carried out with one or more fluorescence-indicator dyes. 3. The method according to claim 1, wherein said measuring the membrane potential of the cell is carried out under voltage clamp assay conditions. 4. The method according to claim 1, wherein said measuring the membrane potential of the cell is carried out under patch recording assay conditions. 5. The method according to claim 1, wherein the cell in (i) and the cell in (ii) are isolated. 6. The method according to claim 1, wherein the level of TRP8 activation is decreased in the presence of the test compound, indicating that the test compound is a TRP8 inhibitor. 7. The method according to claim 6, wherein the test compound inhibits the perception of a bitter taste. 8. The method according to claim 6, wherein the test compound inhibits the perception of a sweet taste. 9. The method according to claim 1, wherein the level of TRPS activation is increased in the presence of the test compound, indicating that the test compound is a TRP8 activator. 10. The method according to claim 9, wherein the test compound enhances the perception of a bitter taste. 11. The method according to claim 9, wherein the test compound enhances the perception of a sweet taste. 12. The method according to claim 1, wherein the level of TRP8 activation is measured by measuring membrane current using physiological techniques.
