Crystal structure of a mutant mineralocorticoid receptor responsible for hypertension.
J.Fagart, J.Huyet, G.M.Pinon, M.Rochel, C.Mayer, M.E.Rafestin-Oblin.
The S810L mutation within the human mineralocorticoid receptor (MR S810L) induces severe hypertension and switches progesterone from antagonist to agonist. Here we report the crystal structures of the ligand-binding domain of MR S810L in complex with progesterone and deoxycorticosterone, an agonist of both wild-type and mutant MRs. These structures, the first for MR, identify the specific contacts created by Leu810 and clarify the mechanism of activation of MR S810L.

Figure 1. Crystal structures of the LBD of MR S810L. (a) Diagram showing LBD-DOC interactions. Hydrogen bonds and van der Waals interactions are solid arrows and dashed lines, respectively. The colors of the residue names are based on the LBD structural elements from which they originate. W indicates a water molecule. (b) Stereo view showing the superimposition of the ligand-binding pockets of MR S810L associated with DOC and with progesterone. The carbon atoms are light blue and white in the DOC -MR S810L and progesterone -MR S810L complexes, respectively. Only polar and charged residues, and two critical hydrophobic residues, are shown. This panel was produced using DINO (
Figure 2.
Figure 2. Transcriptional activation of luciferase activity by mutant MRs in response to aldosterone and progesterone. (a,b) Transfected HEK-293T cells were exposed for 24 h to increasing concentrations of aldosterone (a, full lines), progesterone alone (a, dashed dotted) or 10^-7 M aldosterone plus increasing concentrations of progesterone (b). Transactivations were determined by luciferase activity, normalized to the internal -galactosidase control, and expressed as a percentage of the MR S810L activity at 10^-6 M aldosterone. Each point is the mean s.e.m. of three separate experiments.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
