NCIt definition : Widely expressed human Estrogen Receptors (NR3 Family) are cytoplasmic hormone-activated
receptors that act as nuclear transcription factors composed of an N-terminal transcription
activation/modulation domain, a DNA-binding domain, and a C-terminal steroid-binding
domain. Binding to DNA as a homo- or heterodimer, ESR interacts with NCOA3, NCOA5,
and NCOA6 coactivators. Hormone-ESR complexes appear to recognize discrete upstream
target ERE DNA sequences to regulate gene expression, cell proliferation, and differentiation.
DNA-binding is lost in the absence of ligand. (NCI);
