Estradiol (E2) signaling via estrogen receptor alpha (ERα) is important for the male skeleton as demonstrated by ERα inactivation in both mice and man. ERα mediates estrogenic effects by translocating to the nucleus and there affects gene transcription, but some effects can also be mediated via extra-nuclear actions of the receptor by, e.g., triggering cytoplasmic signaling cascades. ERα contains various domains and the role of activation functio...
