dc.description.abstract | Steroid receptor drugs have been available for more than half a century, but details 24 of the ligand binding mechanism has remained elusive. We solved X-ray structures of 25 the glucocorticoid and mineralocorticoid receptors to identify a conserved plasticity at 26 helix 6-7 region that extend the ligand binding pocket towards the receptor surface. 27 Since none of the endogenous ligands exploit this region, we hypothesized that it 28 constitutes an integral part of the binding event. Extensive all atom unbiased ligand 29 exit and entrance simulations corroborate a ligand binding pathway that gives the 30 observed structural plasticity a key functional role. Kinetic measurements reveal that 31 the receptor residence time correlate with structural rearrangements observed in both 32 structures and simulations. Ultimately, our findings reveal why nature has conserved 33 the capacity to open up this region and highlight how differences in the details of the 34 ligand entry process result in differential evolutionary constraints across the steroid 35 receptors. |
