After estrogen is bound to the receptor protein, it is moved through the rough and smooth endoplasmic reticulum to the nucleus. Estrogen, like other steroids, works directly on the cell nucleus. There, it will either inhibit or stimulate production of certain proteins.

Estrogen receptor are dimer which means that they have an alpha and beta subunit. They are present in the nucleus, not the cytoplasm of cells. They regulate and initiate transcription of DNA to form proteins and enzymes. There are 3 types of estrogen receptors: alpha-alpha, alpha-beta, and beta-beta. The subunits bind to different estrogens with different affinities. There are some estrogen receptors that are attached to the cell membrane of some cells as well.
