Questions and Answers

What happens when the glucocorticoid receptor (GR) binds to glucocorticoid response elements (GRE) in the promoter regions of genes?

  • Activation of inactive multi-protein complexes
  • Inhibition of gene expression
  • Enhancement of GR binding to DNA
  • Transcriptional induction or repression of target genes (correct)

Where is the glucocorticoid receptor (GR) held in the absence of glucocorticoids like cortisol?

  • Mitochondria
  • Endoplasmic reticulum
  • Nucleus
  • Cytosol (correct)

What happens to the glucocorticoid receptor (GR) when cortisol binds to it?

  • It forms a trimer
  • It becomes inactive
  • It dissociates from the regulatory complex (correct)
  • It remains bound to the cytoplasm
