Protein attributes
| Sequence length | 323 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Gustducin-coupled receptor implicated in the perception of bitter compounds in the oral cavity and the gastrointestinal tract. Signals through PLCB2 and the calcium-regulated cation channel TRPM5. |
| Subcellular location | |
| Tissue specificity | Expressed in subsets of taste receptor cells of the tongue and exclusively in gustducin-positive cells. |
| Miscellaneous | Several bitter taste receptors are expressed in a single taste receptor cell. |
| Sequence similarities | Belongs to the G-protein coupled receptor T2R family. |
