'''Glucocorticoid receptor''' (GCR) is the nuclear receptor binding cortisol and glucocorticoids.  GCR regulates genes involved in development, metabolism and immune response.  The glucocorticoid-bound GCR can either up-regulate the expression of anti-inflammatory proteins (transactivation) or repress the expression of pro-inflammatory proteins (transrepression).  GCR contains 5 domains: N terminal regulatory domain; DNA-binding domain (DBD); hinge region; ligand-binding domain (LBD) and C terminal domain.  GCR interacts with nuclear receptor coactivator 2 (NCOA2) which promotes DNA transcription by acylating histones.
