The progesterone receptor is a type of protein found in various tissues in the body, primarily in the uterus, breasts, and ovaries. It plays a crucial role in the reproductive system by binding to the hormone progesterone, which is essential for regulating the menstrual cycle and maintaining pregnancy.
When progesterone binds to its receptor, it activates specific genes that influence cell growth and function. This process is vital for preparing the uterus for implantation of a fertilized egg and supporting early pregnancy. Abnormalities in progesterone receptor function can lead to reproductive disorders and other health issues.
