Probing the role of the cation–π interaction in the binding sites of GPCRs using unnatural amino acids [PDF]
, 2009 We describe a general application of the nonsense suppression methodology for unnatural amino acid incorporation to probe drug–receptor interactions in functional G protein-coupled receptors (GPCRs), evaluating the binding sites of both the M2 muscarinic

Crystallization of G Protein-Coupled Receptors [PDF]
, 2013 Oligomerization is one of several mechanisms that can regulate the activity of G protein-coupled receptors (GPCRs), but little is known about the structure of GPCR oligomers. Crystallography and NMR are the only methods able to reveal the details of receptor-receptor interactions at an atomic level, and several GPCR homodimers already have been ...

FEBS Letters, EarlyView.LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Quantifying selection in immune receptor repertoires [PDF]
Proc Natl Acad Sci USA 111(27) 9875-9880 (2014), 2014 The efficient recognition of pathogens by the adaptive immune system relies on the diversity of receptors displayed at the surface of immune cells. T-cell receptor diversity results from an initial random DNA editing process, called VDJ recombination, followed by functional selection of cells according to the interaction of their surface receptors with

Point Substitutions in G Protein-Coupled Receptors [PDF]
, 2021 G protein-coupled receptors (GPCRs) are proteins that are important in physiological regulatory processes within the body, and for this reason are important drug targets.

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Rules and mechanisms governing G protein coupling selectivity of GPCRs
Cell Reports, 2023 Summary: G protein-coupled receptors (GPCRs) convert extracellular stimuli into intracellular signaling by coupling to heterotrimeric G proteins of four classes: Gi/o, Gq, Gs, and G12/13.

G-Protein Coupled Receptors Targeted by Analgesic Venom Peptides
Toxins, 2017 Chronic pain is a complex and debilitating condition associated with a large personal and socioeconomic burden. Current pharmacological approaches to treating chronic pain such as opioids, antidepressants and anticonvulsants exhibit limited efficacy in ...

Fusion protein strategies for cryo-EM study of G protein-coupled receptors
Nature Communications, 2022 Here, Zhang et al. explore fusion protein strategies to facilitate cryo-EM structural studies of GPCRs alone- without signal transducers- in ligand bound or unliganded form.

Functional characterisation of G protein-coupled receptors [PDF]
, 2018 Characterisation of receptors can involve either assessment of their ability to bind ligands or measure receptor activation as a result of agonist or inverse agonist interactions.
