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

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

G-protein coupled receptor structure
Biochimica 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,

Role of G-protein coupled receptors in cardiovascular diseases
Frontiers in Cardiovascular Medicine, 2023 Cardiovascular diseases (CVDs) are the leading cause of death globally, with CVDs accounting for nearly 30% of deaths worldwide each year. G-protein-coupled receptors (GPCRs) are the most prominent family of receptors on the cell surface, and play an ...

Inhibition of Subsets of G Protein-coupled Receptors by Empty Mutants of G Protein α Subunits in Go, G11, and G16 [PDF]
, 2000 We previously reported that the xanthine nucleotide binding Goα mutant, GoαX, inhibited the activation of Gi-coupled receptors. We constructed similar mutations in G11α and G16α and characterized their nucleotide binding and receptor interaction.

On the hierarchical classification of G Protein-Coupled Receptors [PDF]
, 2007 Motivation: G protein-coupled receptors (GPCRs) play an important role in many physiological systems by transducing an extracellular signal into an intracellular response. Over 50% of all marketed drugs are targeted towards a GPCR.

G-protein-coupled receptor kinases
Kidney International, 1996 beta-Adrenergic receptors are prototypes of the many G-protein-coupled receptors. Activation and inactivation of these receptors are regulated by multiple mechanisms which can affect either their function or their expression. The most obvious changes of such receptor systems are induced by activation of the receptors themselves by their respective ...

Regulating G protein-coupled receptors by topological inversion
eLife, 2019 G protein-coupled receptors (GPCRs) are a family of proteins containing seven transmembrane helices, with the N- and C-terminus of the protein located at the extracellular space and cytosol, respectively.

G protein-coupled receptor signalling in astrocytes in health and disease: A focus on metabotropic glutamate receptors [PDF]
, 2012 Work published over the past 10–15 years has caused the neuroscience community to engage in a process of constant re-evaluation of the roles of glial cells in the mammalian central nervous system.
