ERβ
Extracted from the Wikipedia article Estrogen receptor beta.
Tissue distribution
ERβ is expressed by many tissues including the uterus, blood monocytes and tissue macrophages, colonic and pulmonary epithelial cells and in prostatic epithelium and in malignant counterparts of these tissues. Also, ERβ is found throughout the brain at different concentrations in different neuron clusters. ERβ is also highly expressed in normal breast epithelium, although its expression declines with cancer progression. ERβ is expressed in all subtypes of breast cancer. Controversy regarding ERβ protein expression has hindered study of ERβ, but highly sensitive monoclonal antibodies have been produced and well-validated to address these issues.
