DESCRIPTION

Also known as GCR_RAT, Nr3c1, Grl. 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. Involved in chromatin remodeling (PubMed:12917342). Plays a role in rapid mRNA degradation by binding to the 5' UTR of target mRNAs and interacting with PNRC2 in a ligand-dependent manner which recruits the RNA helicase UPF1 and the mRNA-decapping enzyme DCP1A, leading to RNA decay (By similarity). 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 (By similarity)., Has transcriptional activation and repression activity. Mediates glucocorticoid-induced apoptosis. Promotes accurate chromosome segregation during mitosis. May act as a tumor suppressor. May play a negative role in adipogenesis through the regulation of lipolytic and antilipogenic gene expression. Interacts with GRIP1 (By similarity). Heteromultimeric cytoplasmic complex with HSP90AA1, HSPA1A/HSPA1B, and FKBP5 or another immunophilin such as PPID, STIP1, or the immunophilin homolog PPP5C (PubMed:21730050). Upon ligand binding FKBP5 dissociates from the complex and FKBP4 takes its place, thereby linking the complex to dynein and mediating transport to the nucleus, where the complex dissociates (By similarity). Probably forms a complex composed of chaperones HSP90 and HSP70, co-chaperones CDC37, PPP5C, TSC1 and client protein TSC2, CDK4, AKT, RAF1 and NR3C1; this complex does not contain co-chaperones STIP1/HOP and PTGES3/p23 (By similarity). Directly interacts with UNC45A (By similarity). Binds to DNA as a homodimer, and as heterodimer with NR3C2 or the retinoid X receptor (By similarity). Binds STAT5A and STAT5B homodimers and heterodimers (By similarity). Interacts with NRIP1, POU2F1, POU2F2 and TRIM28 (PubMed:10364267, PubMed:10480874). Interacts with several coactivator complexes, including the SMARCA4 complex, CREBBP/EP300, TADA2L (Ada complex) and p160 coactivators such as NCOA2 and NCOA6 (PubMed:9111344, PubMed:10866662). Interaction with BAG1 inhibits transactivation (By similarity). Interacts with HEXIM1 and TGFB1I1 (By similarity). Interacts with NCOA1 (PubMed:12917342). Interacts with NCOA3, SMARCA4, SMARCC1, SMARCD1, and SMARCE1 (PubMed:12917342, PubMed:12118039). Interacts with CLOCK, CRY1 and CRY2 in a ligand-dependent fashion (By similarity). Interacts with CIART (By similarity). Interacts with RWDD3 (PubMed:23508108). Interacts with UBE2I/UBC9 and this interaction is enhanced in the presence of RWDD3 (PubMed:23508108). Interacts with NR4A3 (via nuclear receptor DNA-binding domain), represses transcription activity of NR4A3 on the POMC promoter Nur response element (NurRE) (By similarity). Directly interacts with PNRC2 to attract and form a complex with UPF1 and DCP1A; the interaction leads to rapid mRNA degradation (By similarity). Interacts with GSK3B (By similarity). Interacts with FNIP1 and FNIP2 (By similarity). Interacts (via C-terminus) with HNRNPU (via C-terminus) (By similarity). Interacts with MCM3AP (By similarity). Interacts (via domain NR LBD) with HSP90AA1 and HSP90AB1 (By similarity). In the absence of hormonal ligand, interacts with TACC1 (By similarity).
