Brain is a network of hundred billion of neurons connected by quadrillions of synapses. The strength of synaptic connections is altered in response to different stimuli in a bidirectional manner, called synaptic plasticity, which is widely believed as a cellular mechanism of learning and memory. Glutamate receptors play a pivotal role in regulating multiple forms of synaptic plasticity, essential for brain function, and have been implicated in neurodevelopmental disorders and neurodegenerative disorders. Thus, identifying the molecular mechanisms regulating glutamate receptor function is important for understanding both normal CNS function and the pathogenesis of brain disorders.My lab has been interested in how glutamate receptor function is regulated by post-translational modifications such as phosphorylation, SUMOylation, ubiquitination, and neddylation under various physiological and pathological conditions. In addition, we study how several interacting molecules, including auxiliary subunits, determine the function of glutamate receptors. Finally we analyze the molecular mechanisms of synaptopathy, that is, how synaptic dysfunction leads to the pathogenesis of autism, depression, Alzheimer’s disease, and ALS. We apply various methods in our research including molecular cellular biology, biochemistry, confocal imaging, and animal model.
