TAS2R16. a member of the human bitter taste receptor family (TAS2Rs), is a G protein-coupled receptor (GPCR) primarily expressed in taste receptor cells of the tongue. It detects bitter compounds, particularly β-glucosides (e.g., salicin, amygdalin) found in plants, triggering aversive responses that may reflect an evolutionary defense mechanism against toxins. Beyond taste perception, TAS2R16 is ectopically expressed in extraoral tissues like the respiratory tract, gut, and brain, suggesting broader physiological roles in nutrient sensing, metabolic regulation, and innate immunity.
As a recombinant protein, TAS2R16 is produced using engineered cell systems (e.g., HEK293 cells) to enable structural and functional studies. Its seven-transmembrane helical structure, ligand-binding pocket, and signaling pathways (via gustducin or Gi/o proteins) are research focuses. Recombinant TAS2R16 facilitates high-throughput screening of agonists/antagonists, with applications in food science (bitter-masking agents) and drug discovery (targeting TAS2Rs in airway innate immunity or metabolic disorders).
Studies also explore genetic variations (e.g., the *TAS2R16* K172N polymorphism) linked to bitter sensitivity differences and disease risks, including chronic rhinosinusitis. Challenges remain in resolving its full 3D structure and clarifying signaling crosstalk in non-gustatory tissues.
