Arrestins as programmable integrators of GPCR signaling: structural microstates, spatiotemporal logic, and therapeutic control
Arrestins were originally defined as terminators of G protein-coupled receptor (GPCR) signaling, yet structural and mechanistic advances now reveal them as programmable, spatiotemporal integrators of cellular signaling. Recent cryo-electron microscopy studies have revealed a diverse spectrum of GPCR–arrestin engagement...
