GPCR kinases (GRKs) and β-arrestins are activated by agonist-bound GPCRs and interact with the receptor receptor internalization. β-Arrestins facilitate this process by interacting with adapter protein 2 interaction and activation (Maharana et al. 2023). This approach reveals binding interfaces and interactions between GPCRs and β-arrestins, paving the way GPCR–β-Arrestin complexes: versatile scaffolding platforms β-arrestins exhibit interactions with over

September 2022 "Receptor-activity-modifying proteins (RAMPs) are ubiquitously expressed membrane proteins However, it is unknown whether and how RAMP proteins may affect PTH1R function. These data uncover a critical role of RAMPs in the activation and signaling of a GPCR that may provide a new venue for highly specific modulation of GPCR function and advanced drug design."

G protein-coupled receptors (GPCRs) have been shown to play integral roles in Alzheimer's disease pathogenesis However, it is unclear how diverse GPCRs similarly affect Aβ and tau pathogenesis. GPCRs share a common mechanism of action via the β-arrestin scaffolding signaling complexes, which not only serve to desensitize GPCRs by internalization, but also mediate multiple downstream signaling events As signaling via the GPCRs, β2-adrenergic receptor (β2AR), and metabotropic glutamate receptor 2 (mGluR2

G protein-coupled receptors (GPCRs) are among the most promising drug targets. Specifically controlling the activity of GPCR dimers with ligands is a good approach to clarify their This region corresponds to the sodium ion binding site in class A GPCRs that controls the basal state reveal the possibility of developing allosteric compounds able to specifically modulate the activity of GPCR homo- and heterodimers by acting at their transmembrane interface.

In practice, these criteria test the purity of interaction. GPCR innovation is accelerating—those who act now will define tomorrow’s breakthroughs.

Axon regeneration in response to injury is determined by the interaction between the extracellular environment demonstrate that the chemoreceptor genes, srg-36 and srg-37, which encode G protein-coupled receptors (GPCRs Here, we show that SRG-36 and SRG-37 act as upstream GPCRs that activate EGL-30. SRG-36 and SRG-37 are GPCRs for the dauer-inducing ascaroside, ascr#5. Thus, ascaroside signaling promotes axon regeneration by activating the GPCR-Gqα pathway.
