Summaries for TAS2R46 Gene

Entrez Gene Summary for TAS2R46 Gene

  • TAS2R46 belongs to the large TAS2R receptor family. TAS2Rs are expressed on the surface of taste receptor cells and mediate the perception of bitterness through a G protein-coupled second messenger pathway (Conte et al., 2002 [PubMed 12584440]). For further information on TAS2Rs, see MIM 604791.[supplied by OMIM, Sep 2009]

GeneCards Summary for TAS2R46 Gene

TAS2R46 (Taste 2 Receptor Member 46) is a Protein Coding gene. Among its related pathways are Peptide ligand-binding receptors and Taste transduction. GO annotations related to this gene include G-protein coupled receptor activity and bitter taste receptor activity. An important paralog of this gene is TAS2R43.

UniProtKB/Swiss-Prot for TAS2R46 Gene

  • Receptor that may play a role in the perception of bitterness and is gustducin-linked. May play a role in sensing the chemical composition of the gastrointestinal content. The activity of this receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5 (By similarity). In airway epithelial cells, binding of bitter compounds increases the intracellular calcium ion concentration and stimulates ciliary beat frequency (By similarity).
