Heterotrimeric G protein signalling in the plant kingdom [PDF]

open access: yesOpen 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.

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

open access: yesHepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

Optogenetic activation of heterotrimeric G-proteins by LOV2GIVe, a rationally engineered modular protein

open access: yeseLife, 2020

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

open access: yes, 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]

open access: yes, 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]

open access: yes, 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

open access: yesNature 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]

open access: yes, 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

open access: yesCells, 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
