RecName: Full=Taste receptor type 2 member 43; Short=T2R43

Protein Classification

G protein-coupled receptor family protein; olfactory receptor subfamily 2A protein( domain architecture ID 11606659)

G protein-coupled receptor family protein is a seven-transmembrane G protein-coupled receptor (7TM-GPCR) family protein which typically transmits an extracellular signal into the cell by the conformational rearrangement of the 7TM helices and by the subsequent binding and activation of an intracellular heterotrimeric G protein; GPCR ligands include light-sensitive compounds, odors, pheromones, hormones, and neurotransmitters| olfactory receptor (OR) subfamily 2A protein, such as human olfactory receptor 2A2 and related proteins in other mammals and sauropsids; ORs play a central role in olfaction, the sense of smell, and belong to the class A rhodopsin-like family of seven-transmembrane G protein-coupled receptors (7TM GPCRs)

mammalian taste receptor 2, subtype 43, and related proteins, member of the seven-transmembrane G protein-coupled receptor superfamily; This group includes the mammalian taste receptor 2 (T2R) subtype 43, which functions as a bitter taste receptor. Also included are the closely related taste receptors TAS2R19, TAS2R20, TAS2R30, TAS2R31, TAS2R45 and TAS2R50. The human TAS2R family contains about 25 functional members, which are glycoproteins and have the ability to form both homomeric and heteromeric receptor complexes. Five basic tastes are perceived by animals: bitter, sweet, sour, salty, and umami (the taste of glutamate, MSG). Among these, sour and salty are mediated by ion channels, while the perception of umami and sweet tastes is mediated by the TAS1R taste receptors, which belong to the class C GPCR family. The TAS2Rs in humans have a short extracellular N-terminus and the ligand binds within the transmembrane domain, whereas the TAS1Rs have a large N-terminal extracellular domain composed of the Venus flytrap module that forms the orthosteric (primary) ligand binding site. Signal transduction of bitter taste involves binding of bitter compounds to TAS2Rs linked to the alpha-subunit of gustducin, a heterotrimeric G protein expressed in taste receptor cells. This G-alpha subunit stimulates phosphodiesterase and decreases cAMP and cGMP levels. Further steps in the signaling cascade is still unknown. The beta-gamma-subunit of gustducin also mediates bitter taste transduction by activating phospholipase C, which leads to an increased formation of IP3 (inositol triphosphate) and DAG (diacylglycerol), thereby causing release of Ca2+ from intracellular stores and enhanced neurotransmitter release.

Taste receptor protein (TAS2R); This family consists of several forms of eukaryotic taste receptor proteins (TAS2Rs). TAS2Rs are G protein-coupled receptors expressed in subsets of taste receptor cells of the tongue and palate epithelia in humans and mice, and are organized in the genome in clusters. The proteins are genetically linked to loci that influence bitter perception in mice and humans.

8-290 1.72e-69

mammalian taste receptor 2, subtype 42, member of the seven-transmembrane G protein-coupled receptor superfamily; This group includes the mammalian taste receptor 2 (TAS2R) subtype 42, which functions as a bitter taste receptor. The human TAS2R family contains about 25 functional members, which are glycoproteins and have the ability to form both homomeric and heteromeric receptor complexes. Five basic tastes are perceived by animals: bitter, sweet, sour, salty, and umami (the taste of glutamate, MSG). Among these, sour and salty are mediated by ion channels, while the perception of umami and sweet tastes is mediated by the TAS1R taste receptors, which belong to the class C GPCR family. The TAS2Rs in humans have a short extracellular N-terminus and the ligand binds within the transmembrane domain, whereas the TAS1Rs have a large N-terminal extracellular domain composed of the Venus flytrap module that forms the orthosteric (primary) ligand binding site. Signal transduction of bitter taste involves binding of bitter compounds to TAS2Rs linked to the alpha-subunit of gustducin, a heterotrimeric G protein expressed in taste receptor cells. This G-alpha subunit stimulates phosphodiesterase and decreases cAMP and cGMP levels. Further steps in the signaling cascade is still unknown. The beta-gamma-subunit of gustducin also mediates bitter taste transduction by activating phospholipase C, which leads to an increased formation of IP3 (inositol triphosphate) and DAG (diacylglycerol), thereby causing release of Ca2+ from intracellular stores and enhanced neurotransmitter release.

The beta-gamma-subunit of gustducin also mediates bitter taste transduction by activating phospholipase C, which leads to an increased formation of IP3 (inositol triphosphate) and DAG (diacylglycerol), thereby causing release of Ca2+ from intracellular stores and enhanced neurotransmitter release.

mammalian taste receptor 2, subtype 3, member of the seven-transmembrane G protein-coupled receptor superfamily; This group includes the mammalian taste receptor 2 (TAS2R) subtype 3, which functions as a bitter taste receptor. The human TAS2R family contains about 25 functional members, which are glycoproteins and have the ability to form both homomeric and heteromeric receptor complexes. Five basic tastes are perceived by animals: bitter, sweet, sour, salty, and umami (the taste of glutamate, MSG). Among these, sour and salty are mediated by ion channels, while the perception of umami and sweet tastes is mediated by the TAS1R taste receptors, which belong to the class C GPCR family. The TAS2Rs in humans have a short extracellular N-terminus and the ligand binds within the transmembrane domain, whereas the TAS1Rs have a large N-terminal extracellular domain composed of the Venus flytrap module that forms the orthosteric (primary) ligand binding site. Signal transduction of bitter taste involves binding of bitter compounds to TAS2Rs linked to the alpha-subunit of gustducin, a heterotrimeric G protein expressed in taste receptor cells.

mammalian taste receptor 2, subtype 38, member of the seven-transmembrane G protein-coupled receptor superfamily; This group includes the mammalian taste receptor 2 (T2R) subtype 38, which functions as a bitter taste receptor. Genetic variants of human TAS2R38 influence the ability to taste synthetic compounds 6-n-propylthiouracil (PROP) and phenylthiocarbamide (PTC). Thus, sensitivity to the bitter taste of PROP is often used as a marker for individual differences in taste perception that can affect food preferences and intake. The human TAS2R family contains about 25 functional members, which are glycoproteins and have the ability to form both homomeric and heteromeric receptor complexes. Five basic tastes are perceived by animals: bitter, sweet, sour, salty, and umami (the taste of glutamate, MSG).

mammalian taste receptor 2, subtype 41, member of the seven-transmembrane G protein-coupled receptor superfamily; This group includes the mammalian taste receptor 2 (TAS2R) subtype 41, which functions as a bitter taste receptor. Also included is the closely related TAS2R60. The human TAS2R family contains about 25 functional members, which are glycoproteins and have the ability to form both homomeric and heteromeric receptor complexes. Five basic tastes are perceived by animals: bitter, sweet, sour, salty, and umami (the taste of glutamate, MSG). Among these, sour and salty are mediated by ion channels, while the perception of umami and sweet tastes is mediated by the TAS1R taste receptors, which belong to the class C GPCR family. The TAS2Rs in humans have a short extracellular N-terminus and the ligand binds within the transmembrane domain, whereas the TAS1Rs have a large N-terminal extracellular domain composed of the Venus flytrap module that forms the orthosteric (primary) ligand binding site. Signal transduction of bitter taste involves binding of bitter compounds to TAS2Rs linked to the alpha-subunit of gustducin, a heterotrimeric G protein expressed in taste receptor cells. This G-alpha subunit stimulates phosphodiesterase and decreases cAMP and cGMP levels. Further steps in the signaling cascade is still unknown. The beta-gamma-subunit of gustducin also mediates bitter taste transduction by activating phospholipase C, which leads to an increased formation of IP3 (inositol triphosphate) and DAG (diacylglycerol), thereby causing release of Ca2+ from intracellular stores and enhanced neurotransmitter release.
