WebbThe binding of a ligand to a macromolecule is often enhanced if there are already other ligands present on the same macromolecule (this is known as cooperative binding). The … WebbThe orphan receptors bind the RAREoct site with a much higher affinity than the RAR:RXR heterodimers. This high binding affinity provides ARP-1/COUP-TFII and EAR-3/COUP-TFI with the ability to compete with and even displace RAR:RXR from the RAREoct site and subsequently to actively silence the Oct-3/4 promoter.
