β-arrestin1 directly engages Gαs to sustain endosomal GPCR signaling

β-arrestin1 acts as a positive regulator that holds Gαs in a signaling-competent state, providing a unifying structural basis for sustained endosomal GPCR signaling.

Arrestins as programmable integrators of GPCR signaling: structural microstates, spatiotemporal logic, and therapeutic control

Recent structural, biochemical, and physiological insights are synthesized to outline how arrestins decode regulatory inputs into signaling outcomes and how this knowledge enables the development of next-generation, structure-guided GPCR therapeutics.

Structural basis for small-molecule agonism at GCGR and GIPR via a conserved intracellular allosteric site.

Findings reveal a conserved intracellular allosteric activation mechanism across multiple class B GPCRs and identify SIM1 and its analogs as valuable chemical tools for investigating receptor-specific intracellular allosteric regulation and G protein-preferential signaling.
