Profiling of HCAR1 signalling reveals Gαi/o and Gαs activation without β‐arrestin recruitment and the discovery of an allosteric agonist

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Lactate, historically viewed as a metabolic by‐product, has emerged as a signalling molecule via the G protein–coupled receptor Hydroxycarboxylic Acid Receptor 1 (HCAR1). The receptor is primarily expressed in adipocytes but also found in various other tissues.

In vivo assembly and large-scale purification of a GPCR - Gα fusion with Gβγ, and characterization of the active complex.

open access: yesPLoS ONE, 2019
G protein coupled receptors (GPCRs) are central players in recognizing a variety of stimuli to mediate diverse cellular responses. This myriad of functions is accomplished by their modular interactions with downstream intracellular transducers, such as ...

Feedback control of excitability and high K+ induced epileptiform bursts in male rat hippocampal slices with a photocaged adenosine A1 receptor agonist

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Adenosine is a potent regulator of neurotransmission and neuronal excitability, through activation of Gi coupled adenosine A1 receptors (A1Rs). Adenosine has gained interest as an anticonvulsant because of its endogenous involvement in ending seizure activity, but peripheral side effects require local application.

Functional selectivity of GPCR-directed drug action through location bias. [PDF]

open access: yes, 2017
G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes.

Alpha‐2‐adrenoreceptor agonists as analgesic drugs in equine medicine

open access: yesEquine Veterinary Education, EarlyView.
Summary Managing pain in horses is challenging despite the availability of nonsteroidal anti‐inflammatory drugs, local anaesthetics, opioids and α2‐adrenoreceptor agonists. While α2‐agonists are widely used for sedation and restraint, their analgesic properties remain underutilised.

RGG1, Involved in the Cytokinin Regulatory Pathway, Controls Grain Size in Rice

open access: yesRice, 2020
Heterotrimeric GTP binding proteins (G proteins) and cytokinin play important roles in regulating plant growth and development. However, little is known about the mechanism by which they coordinate the regulation of grain size in rice.

Heterotrimeric G Protein–Coupled Signaling in Plants [PDF]

open access: yesAnnual Review of Plant Biology, 2014
Investigators studying G protein–coupled signaling—often called the best-understood pathway in the world owing to intense research in medical fields—have adopted plants as a new model to explore the plasticity and evolution of G signaling. Much research on plant G signaling has not disappointed. Although plant cells have most of the core elements found

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

open access: yesThe FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Heterotrimeric G-protein signaling and light response Two signaling pathways coordinated for optimal adjustment to nature

open access: yesCommunicative & Integrative Biology, 2009
Almost all creatures have invented sophisticated mechanisms to adjust their developmental and metabolic processes to the changing light intensities in day and night.

Activation of phospholipase C beta 2 by the alpha and beta gamma subunits of trimeric GTP-binding protein [PDF]

open access: yes, 1993
Cotransfection assays were used to show that the members of the GTP-binding protein Gq class of alpha subunits could activate phospholipase C (PLC) beta 2.
