COMPOSITIONS AND METHODS FOR PROVIDING OR MODULATING SWEET TASTE AND METHODS OF SCREENING THEREFOR

摘要

The present invention provides methods for identifying a molecule that provides or enhances a sweet taste in the mouth and compositions containing such molecules. The methods involve determining the effect of a variety of known or new compounds on expression or functional activity of a glucose-transporter protein of the activity of an ATP-gated K+ channel (KATP) in a mammalian oral cell, taste cell, or heterologous cell that expresses the protein or channel.
