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.

Frizzled Proteins are bona fide G Protein-Coupled Receptors [PDF]
, 2009 Receptors of the Frizzled family initiate Wnt ligand-dependent signaling controlling multiple steps in organism development and highly conserved in evolution. Misactivation of the Wnt/Frizzled signaling is cancerogenic.

Dual positive and negative regulation of GPCR signaling by GTP hydrolysis [PDF]
, 2009 G protein-coupled receptors (GPCRs) regulate a variety of intracellular pathways through their ability to promote the binding of GTP to heterotrimeric G proteins. Regulator of G protein signaling (RGS) proteins increase the intrinsic GTPase activity of G-

Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]
, 2017 Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Stabilization of G protein-coupled receptors by point mutations
Frontiers in Pharmacology, 2015 G protein-coupled receptors (GPCRs) are flexible integral membrane proteins involved in transmembrane signaling. Their involvement in many physiological processes makes them interesting targets for drug development.

Allostery of atypical modulators at oligomeric G protein-coupled receptors
Scientific Reports, 2021 Many G protein-coupled receptors (GPCRs) are therapeutic targets, with most drugs acting at the orthosteric site. Some GPCRs also possess allosteric sites, which have become a focus of drug discovery.
