The TAS2R14 protein, 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, where it mediates the detection of bitter compounds. As part of the TAS2R subfamily, it plays a critical role in recognizing a wide range of bitter-tasting substances, including toxic alkaloids and plant-derived compounds, thereby triggering aversive responses to protect against ingestion of harmful substances. Structurally, it features seven transmembrane helices typical of GPCRs, with extracellular domains involved in ligand binding.
Beyond taste perception, TAS2R14 exhibits extraoral expression in tissues like the respiratory tract, gastrointestinal system, and immune cells, suggesting roles in nutrient sensing, pathogen defense, and mucosal immunity. Its activation in non-gustatory tissues has been linked to physiological processes such as bronchodilation, gut hormone secretion, and anti-inflammatory responses.
Recombinant TAS2R14 protein, produced via heterologous expression systems (e.g., mammalian or insect cells), is essential for studying receptor-ligand interactions, signaling mechanisms (via Gα-gustducin or Gαi pathways), and calcium flux dynamics. This tool has advanced research into bitter receptor pharmacology, enabling drug discovery for conditions like asthma, metabolic disorders, and taste-related pathologies. Challenges remain in resolving its full 3D structure and identifying all bioactive ligands, highlighting its potential as a therapeutic target.
