Compartmentalisation in cAMP signalling: A phase separation perspective

open access: yesBritish Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

G-protein β subunit AGB1 positively regulates salt stress tolerance in Arabidopsis

open access: yesJournal of Integrative Agriculture, 2015
The heterotrimeric GTP-binding proteins (G-proteins) in eukaryotes consisted of α, β and γ subunits and are important in molecular signaling by interacting with G-protein-coupled receptors (GPCR), on which to transduce signaling into the cytoplast ...

The potential for biased signalling in the P2Y receptor family of GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Insulin signaling inhibits the 5-HT2C receptor in choroid plexus via MAP kinase

open access: yesBMC Neuroscience, 2003
Background G protein-coupled receptors (GPCRs) interact with heterotrimeric GTP-binding proteins (G proteins) to modulate acute changes in intracellular messenger levels and ion channel activity.

Structural basis for activation of trimeric Gi proteins by multiple growth factor receptors via GIV/Girdin. [PDF]

open access: yes, 2014
A long-standing issue in the field of signal transduction is to understand the cross-talk between receptor tyrosine kinases (RTKs) and heterotrimeric G proteins, two major and distinct signaling hubs that control eukaryotic cell behavior.

A supramolecular assembly of cone‐specific G‐protein and cryptochrome 4a on lipid bilayer

open access: yesThe FEBS Journal, EarlyView.
Immobilized phospholipid bilayers on a sensor chip surface serve as membrane platform to investigate critical protein–lipid and protein–protein interaction processes by surface plasmon resonance. The putative magnetoreceptor cryptochrome 4a and the myristoylated cone‐specific G‐protein α‐subunit (Gtα) bind with high affinity to immobilized lipid ...

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.

Galpha 12 and Galpha 13 Are Phosphorylated during Platelet Activation [PDF]

open access: yes, 1996
The ubiquitously expressed G-proteins G12 and G13 whose function is currently not clear have been shown to be activated in platelet membranes through receptors that stimulate platelet aggregation. We used intact human platelets to determine whether alpha

A Model for Direction Sensing in Dictyostelium Discoideum: Ras Activity and Symmetry Breaking Driven by a Gbetagamma- Mediated, Galpha2-Ric8 -- Dependent Signal Transduction Network

open access: yes, 2015
Many eukaryotic cells, including Dictyostelium discoideum (Dicty), neutrophils and other cells of the immune system, can detect and reliably orient themselves in chemoattractant gradients.

Structural determinants at the M2 muscarinic receptor modulate the RGS4-GIRK response to pilocarpine by impairment of the receptor voltage sensitivity. [PDF]

open access: yes, 2017
Membrane potential controls the response of the M2 muscarinic receptor to its ligands. Membrane hyperpolarization increases response to the full agonist acetylcholine (ACh) while decreasing response to the partial agonist pilocarpine.
