nuclear hormone receptor that regulates multiple physiological and pathophysiological processes (Niu 2009)
inhibit erythroid maturation not only through a transcriptional mechanism, but also through a rapid membrane-associated pathway that interferes with EPO receptor signaling (Stellacci 2009)
regulates target genes by associating with specific DNA binding sites, the sequences of which differ between genes (Meijsing 2009)
coactivation of NR3C1 and NFKB alters signaling pathways that are regulated by each factor separately and provide insight into the networks underlying the NR3C1 and NFKB crosstalk
endothelial NR3C1 is a critical regulator of NFKB1 activation and nitric oxide synthesis in sepsis
in the brain, has been implicated, amongst others, in feedback regulation of the hypothalamic-pituitary-adrenal axis, with potential deficits during aging and in depression

ligand-dependent transcription factor of the nuclear receptor superfamily
NR3C1 -dependent repression of elongation-controlled genes was abolished specifically in negative elongation factor-deficient macrophages
both NR3C1 and FOXO1 are required for ANGPTL4 transcription activation, and FOXO1 negatively mediates the suppressive effect of insulin

NR3C1-induced expression of HNF4A may likely contribute to indirect SLC22A1 gene up-regulation by dexamethasone in primary human hepatocytes, but not in hepatocyte-derived tumor cell lines

NR1D1 influences the stability and nuclear localization of NR3C1
MDFIC is a binding partner for NR3C1, and NR3C1 directly represses the MDFIC gene, revealing a negative feedback loop by which glucocorticoids limit MDFIC activity
