Research Interests
Molecular Basis of Synaptic Transmission
Synaptic transmission is an essential cellular event underlying learning and memory. Neuroreceptors, transporters, and ion channels mediate synaptic transmission, and their dysfunction is frequently implicated in brain diseases.
Changes in receptor expression, number, subunit composition, post-translational modifications, and accessory proteins can all regulate the neuroreceptor functions and localizations, and thus support cellular forms of learning. Our laboratory is pursuing molecular mechanisms of neuroreceptors and co-factors expressed in the brain. We are specifically interested in understanding the physiological roles of neuroreceptors and their protein networks.
Current areas of interest within the lab include the following:
(1) dissecting the protein-protein/lipid interactions that are required for synaptic signal transduction in the brain.
(2) elucidating the structure and function of neuroreceptor signaling complexes.
(3) developing new therapeutic drugs and antibodies targeting neuroreceptor complexes.
We use a wide variety of techniques, including single-particle cryo-electron microscopy, X-ray crystallography, biochemical and biophysical techniques, and electrophysiology, to characterize the signaling complexes.
