Heterotrimeric G protein signalling in the plant kingdom [PDF]

Open Biology, 2013
In animals, heterotrimeric G proteins, comprising α-, β-and γ-subunits, perceive extracellular stimuli through cell surface receptors, and transmit signals to ion channels, enzymes and other effector proteins to affect numerous cellular behaviours.

Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]

, 2017
Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have

Regulators of G protein signalling proteins in the human myometrium [PDF]

, 2009
The contractile state of the human myometrium is controlled by extracellular signals that promote relaxation or contraction. Many of these signals function through G proteincoupled receptors at the cell surface, stimulating heterotrimeric G proteins and ...

Gi- and Gs-coupled GPCRs show different modes of G-protein binding. [PDF]

, 2018
More than two decades ago, the activation mechanism for the membrane-bound photoreceptor and prototypical G protein-coupled receptor (GPCR) rhodopsin was uncovered.

GPSM1 impairs metabolic homeostasis by controlling a pro-inflammatory pathway in macrophages

Nature Communications, 2022
G-protein-signaling modulator 1 (GPSM1), an accessory protein which activates heterotrimeric G-protein signaling, exhibits a genetic association with type 2 diabetes.

A Peptide Core Motif for Binding to Heterotrimeric G Protein α Subunits [PDF]

, 2005
Recently, in vitro selection using mRNA display was used to identify a novel peptide sequence that binds with high affinity to G{alpha}i1. The peptide was minimized to a 9-residue sequence (R6A-1) that retains high affinity and specificity for the GDP ...

Gγ and Gα Identity Dictate a G-Protein Heterotrimer Plasma Membrane Targeting

Cells, 2019
Heterotrimeric G-proteins along with G-protein-coupled receptors (GPCRs) regulate many biochemical functions by relaying the information from the plasma membrane to the inside of the cell. The lipid modifications of Gα and Gγ subunits, together

Molecular architecture of Gαo and the structural basis for RGS16-mediated deactivation [PDF]

, 2008
Heterotrimeric G proteins relay extracellular cues from heptahelical transmembrane receptors to downstream effector molecules. Composed of an α subunit with intrinsic GTPase activity and a βγ heterodimer, the trimeric complex dissociates upon receptor ...

Heterotrimeric G-protein signaling is critical to pathogenic processes in Entamoeba histolytica.

PLoS Pathogens, 2012
Heterotrimeric G-protein signaling pathways are vital components of physiology, and many are amenable to pharmacologic manipulation. Here, we identify functional heterotrimeric G-protein subunits in Entamoeba histolytica, the causative agent of amoebic ...
