Receiving and responding to extracellular messages is critical to the proper function of the nervous system. Glutamate is the major excitory neurotransmitter of the CNS, and metabotropic glutamate receptor 5 will play a major role in glutamate signaling. Metabotropic glutamate receptor 5 transmembrane domain is a homodimeric GPCR that resides in the cellular membrane [1]. This domain is a member of the Class C GPCR family and can further be categorized into the Group I subgroup. The transmembrane domain will signal through a Gq/11 pathway. mGlu5 will bind glutamate to the extracellular Venus flytrap domain and the signal will be transduced across the membrane to a heterotrimeric G protein, which will ultimately lead to calcium release and activation of PKC. This will elicit a excitory post-synaptic repose and modulate long term potentiation. Human metabotropic glutamate receptor 5 is found throughout the central nervous system. Areas containing high concentrations of this protein are often involved involved in emotions and higher cognition[2]. The localization of mGlu5 in the CNS and the presence of multiple domains makes mGlu5 a possible target for treating schizophrenia, Fragile X, depression, anxiety,and Alzheimer's disease[2].
