WebMar 8, 2024 · Figure 1 The Bitter Taste Receptor Signaling Pathway: when the ligand binds to the TAS2R, a conformational change is induced. This in turn triggers the dissociation of the α-subunit of gustducin from the β- and γ-subunits. This dissociation of subunits signifies two divergent pathways of signal transduction. WebThe human genome contains ∼29 bitter taste receptors (T2Rs), which are responsible for detecting thousands of bitter ligands, including toxic and aversive compounds. This sentinel function varies between individuals and is underpinned by naturally occurring T2R polymorphisms, which have also been associated with disease. Recent studies have …
