Northwestern University researchers have identified structural features in engineered cell receptors that correlate with ...

Bitter taste receptors are not only expressed in oral cavity cells but also in the gastrointestinal lining. To understand the diverse functions of these receptors, understanding the structure is ...

A bitter taste receptor, TAS2R14, has been shown to respond to both extracellular and intracellular signals. Indeed, it can respond to both signals simultaneously. This finding is especially ...

Receptor proteins, expressed on the cell surface or within the cell, bind to different signaling molecules, known as ligands, initiating cellular responses. Taste receptors, expressed in oral tissues, ...
