The tissue localization of the G‐protein y‐subunit, Gy8, that is specifically expressed in the
olfactory and vomeronasal neurons, was studied in rats at different ages: embryonic day 16 …

Recent molecular analyses have demonstrated that a metabotropic glutamate receptor,
mGluR4, is expressed in taste buds from rat circumvallate and foliate papillae. Behavioral …

We have identified another Drosophila GTP-binding protein (G protein) alpha subunit, dGq
alpha-3. Transcripts encoding dGq alpha-3 are derived from alternative splicing of the dGq …

Expression of the α-subunit of the taste-specific G protein α-gustducin and the glycolytic
enzyme neuron-specific enolase (NSE) was investigated immunohistochemically in human …

The G i/o protein family transduces signals from a diverse group of G protein-coupled
receptors (GPCRs). The observed specificity of G i/o-GPCR coupling and the high rate of G …

Newly identified mammalian taste-cell-specific G protein coupled receptors, and the genes
and cDNA encoding said receptors are described. Specifically, T1R G protein-coupled …

Rat olfactory epithelium and ciliar cytosol of olfactory cells contained the water-soluble 45
kDa protein which was revealed by antibodies against a peptide fragment of the α-subunits …

In mammals, taste perception is a major mode of sensory input. We have identified a novel
family of 40–80 human and rodent G protein–coupled receptors expressed in subsets of …

L‐glutamate and 5′‐ribonucleotides, such as GMP and IMP, elicit the “umami” taste, also
known as the fifth taste. This review will highlight recent advancements in our understanding …

Cellular responses of STC-1 cells to two bitter tastants (denatonium and caffeine) were
investigated using a calcium-imaging technique and compared with the response to …
