Summaries for TAS2R39 Gene

Entrez Gene Summary for TAS2R39 Gene

  • The protein encoded by this gene is a bitter taste receptor that detects green tea catechins, soy isoflavones, and theaflavins. The encoded protein is gustducin-linked and may activate alpha gustducin. This gene is intronless. [provided by RefSeq, Dec 2015]

GeneCards Summary for TAS2R39 Gene

TAS2R39 (Taste 2 Receptor Member 39) is a Protein Coding gene. Among its related pathways are Taste transduction and Signaling by GPCR. GO annotations related to this gene include G-protein coupled receptor activity and bitter taste receptor activity. An important paralog of this gene is TAS2R42.

UniProtKB/Swiss-Prot for TAS2R39 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).
