Mineralocorticoid glucocorticoids. Medical search. Frequent questions

At the cellular level, the actions of glucocorticoids are mediated by a 94-kd protein, the glucocorticoid receptor (GR). The human (h) GR belongs to the steroid/thyroid/retinoic acid superfamily of nuclear receptors and functions as a ligand-dependent transcription factor that regulates the expression of glucocorticoid-responsive genes positively or negatively.
