Protein Structure

UniProt Annotation

Function

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.

Subcellular Localization

Membrane; Multi-pass membrane protein.

Disease Associations

Tissue Specificity

Expressed in subsets of taste receptor cells of the tongue and palate epithelium and exclusively in gustducin- positive cells.
