    proteins that bind estrogen, influencing cell behavior and function

    Estrogen receptors (ER) are proteins found inside and on the surface of certain cells that bind to the hormone estrogen. When estrogen binds to these receptors, it can influence the behavior of the cell, including growth, differentiation, and function. These receptors play a crucial role in various physiological processes, including reproductive health, bone density, and even hair growth. In medical research, ERs are significant in understanding conditions like breast cancer, where the presence of these receptors can influence treatment options.
