Estrogen receptors are proteins that bind to estrogen, a group of steroid hormones. These receptors are crucial for mediating the effects of estrogen throughout the body. There are two main types of estrogen receptors, ERα (estrogen receptor alpha) and ERβ (estrogen receptor beta). These receptors are found in various tissues, including the reproductive organs, brain, bones, and cardiovascular system.

When estrogen binds to its receptor, it triggers a conformational change in the receptor. This change allows the receptor to interact with DNA, influencing the expression of specific genes. This gene regulation is responsible for a wide range of physiological processes. In females, estrogen and its receptors play a key role in the development and maintenance of reproductive tissues, bone density, and cardiovascular health. In males, estrogen also has roles, particularly in the brain and bone health.

The activity of estrogen receptors is essential for normal development and function. Dysregulation of estrogen signaling and receptor activity is implicated in various diseases. For instance, the growth of many breast cancers is fueled by estrogen binding to ERα. Therefore, estrogen receptor status is a critical factor in determining treatment strategies for breast cancer, with therapies often designed to block estrogen's action on these receptors. Research continues to explore the complex roles of estrogen receptors in health and disease.
