Nuclear receptors are a class of intracellular receptors which function as ligand activated transcription factors which up or down regulate the expression of genes. Depending on the nuclear receptor involved, ligand binding results in the dissociation of heat shock proteins, homo- or hetero-dimerization of the receptor, translocation (i.e., active transport) from the cytoplasm into the cell nucleus, and binding to specific sequences of DNA known as hormone response elements (HRE's). The nuclear receptor/DNA complex then recruits other proteins which transcribe DNA downstream from the HRE into messenger RNA and eventually protein which causes a change in cell function. Ligands that bind to nuclear receptors include lipophilic substances such as endogenous hormones, drugs and xenobiotic endocrine disruptors. Because the expression of a large number of genes is regulated by nuclear receptors, ligands that bind to these receptors can have profound effects on the organism.
