Prolactin receptor

The prolactin receptor is a protein found on the surface of certain cells, mainly in the breast and reproductive organs. It acts as a binding site for prolactin, a hormone that promotes milk production in breastfeeding women. When prolactin attaches to this receptor, it triggers a series of signals inside the cell that help regulate functions like milk synthesis and reproductive processes. The receptor ensures that prolactin's effects happen only in specific cells, coordinating the body's reproductive and lactation responses effectively.
