Figure 1.
Figure 1. Structure of the Pm RXR LBD tetramer. (A) Overall ribbon representation of the tetramer consisting of a bottom to bottom dimer of dimers. The two red monomers (A1, B1) form one canonical dimer and the two blue ones, its symmetric (A2, B2). Overlap of monomer A H11/H12 onto monomer B is represented in beige. (B) Stereo view of the superposition of monomer A and B showing the two different H11/H12 conformations. (C) Close view of the ligand binding pocket of monomer A and B. Ligand molecules found in other RXR structures have been added in Pm RXR. The 9-cis retinoic acid from BgRXR (PDB code 1XIU) is depicted in black and the non-activating trans retinoic acid from hRXR (PBD code 1G5Y) in yellow.
