text: Steroid hormone receptors bind DNA as homodimers (or heterodimers, e.g., ERα/ERβ155, 156 with each monomer binding to adjacent major grooves on the same side of the DNA helix.26 Class II nuclear receptors may interact with a different class II nuclear receptor forming a heterodimer, thereby creating a more stable complex with much higher affinity that is thought to enhance transcriptional activity significantly.12
