    摘要: The present invention is based in part on the novel observation that two different types of nuclear receptors, retinoic acid receptors (RAR) and thyroid receptors (TR) dimerize with a RX receptor (RXR) to form a heterodimer which is capable of binding to retinoic acid response elements (RARE) or thyroid receptor response elements (TRE) at physiological conditions. In addition, the present invention discloses that RXR homodimers are capable of binding to RARE's. Based on this observation, the present invention provides novel dimeric proteins, methods of identifying agents capable of binding the dimers of the present invention, methods of identifying DNA sequences capable of being bound by the dimers and methods to identify RA metabolic enzymes and proteins which are required for the activation function of nuclear receptors.
