Disease

GCR_HUMAN Defects in NR3C1 are a cause of glucocorticoid resistance (GCRES) [MIM:138040; also known as cortisol resistance. It is a hypertensive, hyperandrogenic disorder characterized by increased serum cortisol concentrations. Inheritance is autosomal dominant.[1] [2] [3] [4] [5]

Function

GCR_HUMAN Receptor for glucocorticoids (GC). Has a dual mode of action: as a transcription factor that binds to glucocorticoid response elements (GRE), both for nuclear and mitochondrial DNA, and as a modulator of other transcription factors. Affects inflammatory responses, cellular proliferation and differentiation in target tissues. Could act as a coactivator for STAT5-dependent transcription upon growth hormone (GH) stimulation and could reveal an essential role of hepatic GR in the control of body growth. Involved in chromatin remodeling. Plays a significant role in transactivation.[6]

Publication Abstract from PubMed

Mifepristone is known to induce mixed passive antagonist, active antagonist, and agonist effects via the glucocorticoid receptor (GR) pathway. Part of the antagonist effects of mifepristone are due to the repression of gene transcription mediated by the nuclear receptor corepressor (NCoR). Here, we report the crystal structure of a ternary complex of the GR ligand binding domain (GR-LBD) with mifepristone and a receptor-interacting motif of NCoR. The structures of three different conformations of the GR-LBD mifepristone complex show in the oxosteroid hormone receptor family how helix 12 modulates LBD corepressor and coactivator binding. Differences in NCoR binding and in helix 12 conformation reveal how the 11beta substituent in mifepristone triggers the helix 12 molecular switch to reshape the coactivator site into the corepressor site. Two observed conformations exemplify the active antagonist state of GR with NCoR bound. In another conformation, helix 12 completely blocks the coregulator binding site and explains the passive antagonistic effect of mifepristone on GR.
