Metabotropic glutamate receptor 5 (mGluR5) is highly expressed in the mammalian central nervous
system (CNS). It is involved in multiple physiological functions and is a target for treatment of various
CNS disorders, including schizophrenia. We report that Norbin, a neuron-specific protein, physically
interacts with mGluR5 in vivo, increases the cell surface localization of the receptor and positively
regulates mGluR5 signaling. Genetic deletion of Norbin attenuates mGluR5-dependent stable
changes in synaptic function measured as long-term depression or long-term potentiation of synaptic
