Activation of phospholipase C beta 4 by heterotrimeric GTP-binding proteins.

open access: yesJournal of Biological Chemistry, 1994
Transient transfection assays were used to determine how the activity of phospholipase C beta 4, which is preferentially expressed in retina, was regulated. An expression vector carrying the full-length cDNA corresponding to phospholipase C beta 4 was constructed and co-transfected into COS-7 cells together with cDNA encoding the alpha subunits of the ...

The Role of Sodium Fluoride Mouthwash in Regulating FGF-2 and TGF-β Expression in Human Gingival Fibroblasts

open access: yesBiomedicines
Sodium fluoride (NaF) is a fluoride application recommended by the World Health Organization for its efficacy and safety in preventing dental caries. Gingival fibroblasts that constitute the majority of connective tissue cells play a major role in wound ...

Pediatric Encephalopathy: Clinical, Biochemical and Cellular Insights into the Role of Gln52 of GNAO1 and GNAI1 for the Dominant Disease

open access: yesCells, 2021
Heterotrimeric G proteins are immediate transducers of G protein-coupled receptors—the biggest receptor family in metazoans—and play innumerate functions in health and disease. A set of de novo point mutations in GNAO1 and GNAI1, the genes encoding the α-

G protein activation without a GEF in the plant kingdom. [PDF]

open access: yesPLoS Genetics, 2012
Animal heterotrimeric G proteins are activated by guanine nucleotide exchange factors (GEF), typically seven transmembrane receptors that trigger GDP release and subsequent GTP binding.

A Putative Non-Canonical Ras-Like GTPase from P. falciparum: Chemical Properties and Characterization of the Protein. [PDF]

open access: yesPLoS ONE, 2015
During its development the malaria parasite P. falciparum has to adapt to various different environmental contexts. Key cellular mechanisms involving G-protein coupled signal transduction chains are assumed to act at these interfaces.

GTP Binding Assays in Arabidopsis thaliana

open access: yesBio-Protocol, 2013
Signaling through G proteins constitutes an ancient mechanism that functions in the transduction of extracellular signals into intracellular responses. Activation of a proper receptor by a stimuli leads to an exchange of GDP for GTP, the activation of G ...

A Sugarcane G-Protein-Coupled Receptor, ShGPCR1, Confers Tolerance to Multiple Abiotic Stresses

open access: yesFrontiers in Plant Science, 2021
Sugarcane (Saccharum spp.) is a prominent source of sugar and serves as bioenergy/biomass feedstock globally. Multiple biotic and abiotic stresses, including drought, salinity, and cold, adversely affect sugarcane yield.

Role of heterotrimeric Gα proteins in maize development and enhancement of agronomic traits. [PDF]

open access: yesPLoS Genetics, 2018
Plant shoot systems derive from the shoot apical meristems (SAMs), pools of stems cells that are regulated by a feedback between the WUSCHEL (WUS) homeobox protein and CLAVATA (CLV) peptides and receptors.

Role of Structural Dynamics at the Receptor G Protein Interface for Signal Transduction. [PDF]

open access: yesPLoS ONE, 2015
GPCRs catalyze GDP/GTP exchange in the α-subunit of heterotrimeric G proteins (Gαßγ) through displacement of the Gα C-terminal α5 helix, which directly connects the interface of the active receptor (R*) to the nucleotide binding pocket of G.
