Figure 4From: Estrogen receptor transcription and transactivation Structure-function relationship in DNA- and ligand-binding domains of estrogen receptorsSequence alignment of coactivator NR boxes and H12 from ERα and ERβ. (b) Superposition of the H12 structure from ERα complexed with tamoxifen and the ERα structure complexed with DES and a NR box peptide from TIF2/GRIP1.Back to article page
