Description:
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 transmission in the hippocampus. As with mGluR5 knockout mice or mice treated with mGluR5-selective antagonists, Norbin knockout mice showed a behavioral phenotype associated with a rodent model of schizophrenia, as indexed by alterations both in sensorimotor gating and psychotomimetic-induced locomotor activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2796550/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2796550/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Hong -- Westin, Linda -- Nong, Yi -- Birnbaum, Shari -- Bendor, Jacob -- Brismar, Hjalmar -- Nestler, Eric -- Aperia, Anita -- Flajolet, Marc -- Greengard, Paul -- DA 10044/DA/NIDA NIH HHS/ -- MH074866/MH/NIMH NIH HHS/ -- MH66172/MH/NIMH NIH HHS/ -- P01 DA010044/DA/NIDA NIH HHS/ -- P01 DA010044-020002/DA/NIDA NIH HHS/ -- P01 DA010044-030002/DA/NIDA NIH HHS/ -- P01 DA010044-04/DA/NIDA NIH HHS/ -- P01 DA010044-040002/DA/NIDA NIH HHS/ -- P01 DA010044-05/DA/NIDA NIH HHS/ -- P01 DA010044-050002/DA/NIDA NIH HHS/ -- P01 DA010044-06/DA/NIDA NIH HHS/ -- P01 DA010044-060002/DA/NIDA NIH HHS/ -- P01 DA010044-07/DA/NIDA NIH HHS/ -- P01 DA010044-070002/DA/NIDA NIH HHS/ -- P01 DA010044-08/DA/NIDA NIH HHS/ -- P01 DA010044-080002/DA/NIDA NIH HHS/ -- P01 DA010044-09/DA/NIDA NIH HHS/ -- P01 DA010044-090002/DA/NIDA NIH HHS/ -- P01 DA010044-10/DA/NIDA NIH HHS/ -- P01 DA010044-100002/DA/NIDA NIH HHS/ -- P01 DA010044-11/DA/NIDA NIH HHS/ -- P01 DA010044-110005/DA/NIDA NIH HHS/ -- P01 DA010044-12/DA/NIDA NIH HHS/ -- P01 DA010044-120005/DA/NIDA NIH HHS/ -- P01 DA010044-129002/DA/NIDA NIH HHS/ -- P01 DA010044-13/DA/NIDA NIH HHS/ -- P01 DA010044-130005/DA/NIDA NIH HHS/ -- P01 DA010044-139002/DA/NIDA NIH HHS/ -- P01 DA010044-14/DA/NIDA NIH HHS/ -- P01 DA010044-140005/DA/NIDA NIH HHS/ -- P01 DA010044-149002/DA/NIDA NIH HHS/ -- P01 DA010044-14S1/DA/NIDA NIH HHS/ -- P01 DA010044-14S10005/DA/NIDA NIH HHS/ -- P01 DA010044-14S19002/DA/NIDA NIH HHS/ -- P50 MH074866/MH/NIMH NIH HHS/ -- P50 MH074866-010001/MH/NIMH NIH HHS/ -- P50 MH074866-020001/MH/NIMH NIH HHS/ -- P50 MH074866-030001/MH/NIMH NIH HHS/ -- P50 MH074866-039001/MH/NIMH NIH HHS/ -- P50 MH074866-040001/MH/NIMH NIH HHS/ -- P50 MH074866-050001/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1554-7. doi: 10.1126/science.1178496.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, Rockefeller University, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007903" target="_blank"〉PubMed〈/a〉
