Research Area

The research of Yuchi’s group centers on the structure and function of ion channels. Ion channels are the second largest target class for approved drugs. Drugs targeting ion channels are used to treat arrhythmia, neuropathic pain, epilepsy, anxiety and more. The ultimate goal of our group is to understand the physiological and pathological roles of ion channels at the molecular level. The specific questions we are tackling include: 1) the interaction network and regulation of ion channels involved in heart and muscle diseases; 2) how disease-causing mutations perturb the structure and function of critical ion channels; 3) how to target insect ion channels to develop novel biopesticides. To answer these questions, our lab combines a variety of complementary techniques, including X-ray crystallography, electrophysiology, calorimetry, in-silico drug screening, as well as many other biochemical, biophysical and computational methods.
