G protein-coupled receptor dimerisation: molecular basis and relevance to function [PDF]

open access: yes, 2007
The belief that G protein-coupled receptors exist and function as monomeric, non-interacting species has been largely supplanted in recent years by evidence, derived from a range of approaches, that indicate they can form dimers and/or higher-order ...

Designer lipid-like peptides [PDF]

open access: yes, 2011
A crucial bottleneck in membrane protein studies, particularly G-protein coupled receptors, is the notorious difficulty of finding an optimal detergent that can solubilize them and maintain their stability and function. Here we report rapid production of

Current applications of mini G proteins to study the structure and function of G protein-coupled receptors [PDF]

open access: yes, 2018
G protein-coupled receptors (GPCRs) regulate intracellular signalling pathways that contribute to virtually all aspects of cell function. Characterising GPCRs in each of their conformational states is key to understanding their mechanism of action, but ...

Neuropeptide G Protein-Coupled Receptors as Oncotargets

open access: yesFrontiers in Endocrinology, 2018
Neuropeptide G protein-coupled receptors (GPCRs) are overexpressed on numerous cancer cells. In a number of tumors, such as small cell lung cancer (SCLC), bombesin (BB) like peptides and neurotensin (NTS) function as autocrine growth factors whereby they

Metabolite G-Protein Coupled Receptors in Cardio-Metabolic Diseases

open access: yesCells, 2021
G protein-coupled receptors (GPCRs) have originally been described as a family of receptors activated by hormones, neurotransmitters, and other mediators.

Increased accuracy of ligand sensing by receptor diffusion on cell surface [PDF]

open access: yesPhysical Review E 82, 041902 (2010), 2010
The physical limit with which a cell senses external ligand concentration corresponds to the perfect absorber, where all ligand particles are absorbed and overcounting of same ligand particles does not occur. Here we analyze how the lateral diffusion of receptors on the cell membrane affects the accuracy of sensing ligand concentration.

Presynaptic G Protein-Coupled Receptors: Gatekeepers of Addiction?

open access: yesFrontiers in Cellular Neuroscience, 2016
Drug abuse and addiction cause widespread social and public health problems, and the neurobiology underlying drug actions and drug use and abuse is an area of intensive research.

G-protein coupled receptor structure

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2007
Because of their central role in regulation of cellular function, structure/function relationships for G-protein coupled receptors (GPCR) are of vital importance, yet only recently have sufficient data been obtained to begin mapping those relationships. GPCRs regulate a wide range of cellular processes, including the senses of taste, smell, and vision,

A modeling strategy for G-protein coupled receptors

open access: yesAIMS Biophysics, 2016
Cell responses can be triggered via G-protein coupled receptors (GPCRs) that interact with small molecules, peptides or proteins and transmit the signal over the membrane via structural changes to activate intracellular pathways.

Polar Chemoreceptor Clustering by Coupled Trimers of Dimers [PDF]

open access: yesBiophys J 96(2): 453-463 (2009), 2009
Receptors of bacterial chemotaxis form clusters at the cell poles, where clusters act as "antennas" to amplify small changes in ligand concentration. Interestingly, chemoreceptors cluster at multiple length scales. At the smallest scale, receptors form dimers, which assemble into stable timers of dimers.
