Citation | Journal: Sci Adv / Year: 2023 Title: Structural insights into the assembly of gp130 family cytokine signaling complexes. Authors: Yi Zhou / Panayiotis E Stevis / Jing Cao / Kei Saotome / Jiaxi Wu / Arielle Glatman Zaretsky / Sokol Haxhinasto / George D Yancopoulos / Andrew J Murphy / Mark W Sleeman / William C Olson / Matthew C Franklin / Abstract: The interleukin-6 (IL-6) family cytokines signal through gp130 receptor homodimerization or heterodimerization with a second signaling receptor and play crucial roles in various cellular processes. ...The interleukin-6 (IL-6) family cytokines signal through gp130 receptor homodimerization or heterodimerization with a second signaling receptor and play crucial roles in various cellular processes. We determined cryo-electron microscopy structures of five signaling complexes of this family, containing full receptor ectodomains bound to their respective ligands ciliary neurotrophic factor, cardiotrophin-like cytokine factor 1 (CLCF1), leukemia inhibitory factor, IL-27, and IL-6. Our structures collectively reveal similarities and differences in the assembly of these complexes. The acute bends at both signaling receptors in all complexes bring the membrane-proximal domains to a ~30 angstrom range but with distinct distances and orientations. We also reveal how CLCF1 engages its secretion chaperone cytokine receptor-like factor 1. Our data provide valuable insights for therapeutically targeting gp130-mediated signaling. | ||||||
