Figure Lengend Snippet: Fig. 1 Design of the cytokimera GIL-11. a schematic illustration of the tetrameric and hexameric IL-11:IL-11R:gp130 receptor complex possibilities. IL-11 initially binds to IL-11R via site I. gp130 is recruited into this complex via major interactions between site III of IL-11 and D1 (Ig-like) of gp130 and site II of IL- 11 and D2/D3 (cytokine binding module (CBM)) of gp130. b schematic illustration of the trimeric LIF:gp130:LIFR complex. LIF binds via site III to D3/D4 of LIFR and via site II to D2/D3 of gp130. c schematic illustration of the tetrameric GIL-11:IL-11R:gp130:LIFR complex. GIL-11 binds via site III to D3/D4 of LIFR, via site II to D2/D3 of gp130 and via site I to D2/D3 of IL-11R. d schematic illustration (left) and space fill model (right) of the tetrameric GIL-11:IL- 11R:LIFR:gp130 (PDB 6O4P;11 2Q7N;83 1P9M10). GIL-11 binds via site I to IL-11R, via site II to gp130 and via site III to LIFR. e Combined transparent space fill/ band model of GIL-11, red: IL-11, green: exchanged region by LIF. f Structure-based schematic sequence alignment of hIL-11 (PDB 6O4O11), hLIF (PDB 1PVH33) and the resulting GIL-11. Site IIIa,b,c residues are highlighted in green and red boxes.
