Prolactin-releasing peptide receptor

The prolactin-releasing peptide receptor (PrRPR) is a G protein-coupled receptor that is activated by prolactin-releasing peptide (PrRP). It is encoded by the PRLHR gene in humans and is expressed in various tissues, including the hypothalamus, pituitary gland, and pancreas. PrRP is a neuropeptide that plays a role in regulating food intake, energy homeostasis, and stress responses. PrRPR activation stimulates the release of prolactin from the pituitary gland and has been implicated in the regulation of reproductive function, metabolism, and growth.
