ESR1, also known as Estrogen Receptor Alpha, is a protein that belongs to the nuclear hormone receptor family and acts as a transcription factor. It plays a pivotal role in mediating the effects of estrogen, a steroid hormone, in various tissues throughout the body. One of the primary functions of ESR1 is its role in regulating gene expression in response to estrogen binding. In the absence of estrogen, ESR1 resides in the cytoplasm in an inactive state, bound to heat shock proteins. Upon binding of estrogen, ESR1 undergoes a conformational change, dissociates from the heat shock proteins, and translocates to the...
