Predicted potential binding sites for POPs. Binding sites are determined by the docking study between AR/LBD and POPs. PBS1 is a cleft near the N-terminal of the receptor. PBS2 is also known as the bind site of the natural ligand, which is deep inside the receptor. PBS3 is a pocket on the surface near the C-terminal of the receptor. PBS4 is in AF2 region. PBS5 is on the surface of between H7 and H10. The figure on the right panel is obtained by rotating the left panel along z-axis with 180 degrees.
