Gγ 13 is a divergent member of the Gγ subunit family considered to be a component of the
gustducin G-protein heterotrimer involved in bitter and sweet taste reception in taste bud …

G‐protein‐mediated signalling processes are involved in sweet and bitter taste transduction.
In particular, the G protein α‐subunit gustducin has been implicated in these processes. One …

Previous studies have identified many cDNA species that encode a variety of G protein α-
subunits occurring in taste buds. These include the cDNA encoding a taste-bud-specific Gα …

Abstract Background" Type II"/Receptor cells express G protein-coupled receptors (GPCRs)
for sweet, umami (T1Rs and mGluRs) or bitter (T2Rs), as well as the proteins for …

Bitter taste perception is a conserved chemical sense against the ingestion of poisonous
substances in mammals. A multigene family of G-protein-coupled receptors, T2R (so-called …

Taste receptors for sweet, bitter and umami tastants are G-protein coupled receptors
(GPCRs). While much effort has been devoted to understanding G-protein-receptor …

The gustatory system detects tastants and transmits signals to the brain regarding ingested
substances and nutrients. Although tastant receptors and taste signaling pathways have …

We cloned cDNAs for two G protein α-subunits belonging to the Gαq family, each capable of
activating PLCβ, from rat tongue. One is a Gαq in the narrow sense, and the other, termed rat …

A comprehensive reevaluation of the G protein alpha subunit genes specifically expressed
in taste buds in the tongue epithelium of rodents revealed that Gq and G14 of the Gq class …

Heterotrimeric G proteins regulate multiple effectors of which some are mediated via the Gβγ
dimers. There is evidence to suggest that the functions of Gβγ dimers are not shared by all …
