Protein

Taste receptor type 2 member 39

Gene

TAS2R39

Organism
Papio hamadryas (Hamadryas baboon)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

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).By similarity

Miscellaneous

Most taste cells may be activated by a limited number of bitter compounds; individual taste cells can discriminate among bitter stimuli.
