Abstract excerpt
G protein-coupled receptors (GPCRs) are the largest family of cell-surface receptors in humans and regulate numerous physiological processes through the activation of heterotrimeric G proteins. GPCR kinases (GRKs) selectively phosphorylate active GPCRs, which promotes arrestin binding, receptor internalization, and initiation of alternative signaling pathways. GRK5 is a representative member of one of three GRK...
