The QRFPR gene encodes the G-protein coupled receptor 103 protein. This protein acts as a receptor for the orexigenic neuropeptide QRFP. Like other G-protein coupled receptors, the QRFPR protein contains 7 transmembrane domains and is an integral component of the plasma membrane. It carries out its receptor activity and transduces extracellular signals through heterotrimeric G proteins. The protein plays an important role in the cellular response to hormone stimulus.
