The schematic diagram of androgen receptor binding element (ARBE)-directed AR transcriptional regulation. Upper panel shows that agonist-bound AR (red) recognizes an agonist-ARBE in an agonist-specific manner, whereas the bottom panel indicates that antagonist-bound AR (blue) binds to an antagonist-ARBE in an antagonist-dependent manner. The binding of AR to two distinctly different motifs leads to distinct transcriptional outcomes in prostate cancer. The crystal structures of the DNA binding domain (DBD), dihydrotestosterone-ligand binding domain (DHT-LBD) and bicalutamide-LBD are modified from 1R4I, 1T7T and 1Z95, respectively.
