Question

Quizplus · Accepted Answer

The estrogen receptor is a cell signaling protein that binds to estrogen, a hormone that is involved in the regulation of several physiological processes. Once bound to estrogen, the receptor undergoes a conformational change that allows it to bind to DNA and regulate the expression of target genes. This makes it an important player in the genomic response to estrogen, and thus implicated in various hormonal diseases including breast cancer.
