The function of TAS2R14 (taste 2 receptor member 14, Ensembl gene identifier ENSG00000212127) is as follows. Gustducin-linked G protein-coupled receptor that plays a role in the perception of bitterness (PubMed:38600377, PubMed:38776963). The activity of this receptor stimulates GNAT3, activating the gustducin G protein pathway (PubMed:38600377, PubMed:38776963). Likely plays a role in sensing the chemical composition of the gastrointestinal content and other extra-oral tissues via the inhibitory G protein pathways (PubMed:38600377, PubMed:38776963). {ECO:0000269|PubMed:38600377, ECO:0000269|PubMed:38776963}.
