progesterone receptor

The progesterone receptor is a protein found inside certain cells, especially in the reproductive system. It acts like a switch that turns on or off specific genes when it binds with the hormone progesterone, which is important for regulating the menstrual cycle, supporting pregnancy, and other reproductive functions. When progesterone attaches to its receptor, it triggers changes in the cell’s activity, promoting conditions suitable for pregnancy. The presence of these receptors is also important in understanding and treating some conditions like hormone-sensitive cancers, as they can influence how the body responds to hormone therapies.
