Video Summary:
Nuclear receptors are located inside the cell. They bind with a lipophilic ligand molecule. They are transcription factors. They have a ligand-binding domain, DNA binding domain, and transactivation domain. Under resting state, glucocorticoid receptors are located in the cytoplasm and are bound with chaperone protein HSP-90 that prevents its activity. Binding of glucocorticoid causes release of chaperone protein, dimerization, entry into the nucleus, binding with coregulator, binding with DNA, and modulation of transcriptional activity. Because of the involvement of protein synthesis, their effects are slow to appear and slow to disappear.
