3g9i is a 4 chain structure with sequence from Buffalo rat. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
[GCR_RAT] 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 (By similarity).[1]

Publication Abstract from PubMed
Genes are not simply turned on or off, but instead their expression is fine-tuned to meet the needs of a cell. How genes are modulated so precisely is not well understood. The glucocorticoid receptor (GR) regulates target genes by associating with specific DNA binding sites, the sequences of which differ between genes. Traditionally, these binding sites have been viewed only as docking sites. Using structural, biochemical, and cell-based assays, we show that GR binding sequences, differing by as little as a single base pair, differentially affect GR conformation and regulatory activity. We therefore propose that DNA is a sequence-specific allosteric ligand of GR that tailors the activity of the receptor toward specific target genes.
