Figure 3: Conformational changes of FXR LBD induced by ivermectin binding.
From: The antiparasitic drug ivermectin is a novel FXR ligand that regulates metabolism
(a–c) Superposition of the FXR–ivermectin structure (FXR is in green and NCoR-2 motif is in blue ) with the FXR–GW4064 structure (FXR is in salmon red and the SRC1 peptide is in cyan), showing the destabilization of helix12 (a,b) and the pocket size expansion (c) characterized by the conformational changes of helix 2 and helix 6 induced by the binding of ivermectin (indicated by arrows). Ivermectin is in yellow and GW4064 is in purple. (d) Superposition of ivermectin (yellow) with GW4064 (purple).
