Description
Product Characteristics: This gene encodes a member of a family of candidate taste receptors that are members of the G protein-coupled receptor superfamily and that are specifically expressed by taste receptor cells of the tongue and palate epithelia. These apparently intronless genes encode a 7-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered with another 3 candidate taste receptor genes in chromosome 7 and is genetically linked to loci that influence bitter perception. FUNCTION: Gustducin-coupled receptor for denatonium and N(6)-propyl-2-thiouracil 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: Membrane, Multi-pass membrane protein. TISSUE SPECIFICITY: Expressed in subsets of taste receptor cells of the tongue and palate epithelium and exclusively in gustducin-positive cells. MISCELLANEOUS: Several bitter taste receptors are expressed in a single taste receptor cell.,Human Taste R,Taste receptor type 2 member 4, T2R4
Target Information: 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 (By similarity). In airway epithelial cells, binding of denatonium increases the intracellular calcium ion concentration and stimulates ciliary beat frequency (By similarity)
