Extended Data Fig. 8. A proposed mechanism for the bias signaling of CXCR3.

Extended Data Fig. 8

a Superposition of the β-arrestin-coupled and G protein-coupled 5HT2B. b Superposition of the β-arrestin-coupled and G protein-coupled ACM2. c Superposition of the β-arrestin-coupled and G protein-coupled NTR1. In a-c, the receptors are shown as cartoon, and colored cyan for β-arrestin-coupled receptor and gray for G protein-coupled receptor. The Cα atoms of 7.47 and 7.53 are shown as spheres, and the side chains of 7.53 are shown as sticks. The tilt in TM77.47-7.53 is indicated by black arrows. d Superposition of Gi-coupled CXCR3 activated by CXCL11 (violet), PS372424 (yellow), and VUF11222 (blue). e The tilt of TM77.47-7.53 initiated by the insertion of VUF11222. f A proposed model for the mechanism for the biased signaling of CXCR3.
