Here, to address this, we developed an antigen-binding fragment (Fab7) that recognizes both active arrestin2 (β-arrestin1) and arrestin3 (β-arrestin2) without interacting with bound receptor polypeptides. We used Fab7 to determine the structures of both arrestins in complex with atypical chemokine receptor 3 (ACKR3) phosphorylated in different regions of its C-terminal tail by either GRK2 or GRK5 (ref. ). The GRK2-phosphorylated ACKR3 resulted in more heterogeneous 'tail-mode' assemblies, whereas phosphorylation by GRK5 resulted in more rigid 'ACKR3-adjacent' assemblies. Unexpectedly, the finger loops of both arrestins engaged the micelle surface rather than the receptor intracellular pocket, with arrestin3 being more dynamic, partly because of its lack of a membrane-anchoring motif. Thus, both the region of the barcode and the arrestin isoform involved can alter the structure and dynamics of GPCR-arrestin complexes, providing a possible mechanistic basis for unique downstream cellular effects, such as the efficiency of chemokine scavenging and the robustness of arrestin binding in ACKR3. | |||||||||||||||||||||||||||||||||||||||
