  The story for glucocorticoid receptor (GR) has been particularly well worked out, partly because of interest in its action on the promoter-enhancer of mouse mammary tumor virus (MMTV). In a target cell prior to exposure to the hormone, GR is complexed with a heat shock protein Hsp90 and is in an inactive conformation, with the activation domain ...

  Studies have demonstrated that glucocorticoids interact with the CRH receptors in the anterior pituitary, acutely inhibiting the binding of CRH to its receptor and chronically decreasing CRH receptor number (Childs et al. 1986; Schwartz et al. 1986).

  Another mechanism for activating pre-existing factors is covalent modification, such as phosphorylation. In at least some cells, AP1 is activated by phosphorylation. 19.16 (ASC) a) The data in table 4.49 show that insertions in four different regions of the receptor coding sequence cause decreased induction.

  A number of studies in animal models have focused on epigenetic regulation of expression of the glucocorticoid receptor (GR). When GR is expressed at high levels in a given tissue, that tissue becomes more sensitive to glucocorticoid signaling, i.e., lower concentrations of glucocorticoid are necessary for a given level of tissue response.
