Figure 1. Structure of the PXR-RXR LBD Complex.
A. 2.8 Å resolution structure of the complex formed between the ligand binding domains (LBDs) of human PXR (cyan, green) and RXRα (magenta, yellow), with the SRC-1 peptides bound to each LBD indicated. B. In the ligand bound complex of PXR and RXRα, the cholesterol-lowering compound SR12813 is contacted by the amino acid side chains indicated.
