Research Focus

Utilizing various biophysical methods, primarily solid-state NMR, to study the structure and function of protein polymers and protein machines. Typical protein polymers include structural fibers and cytoskeletons under natural conditions, amyloid fibers under pathological conditions, and the phase separation and transition systems of biomacromolecules that have gained attention recently. Solid-state NMR is the optimal method for studying the structure of these protein polymers. Our research holds significant importance in both fundamental and applied aspects: expanding existing knowledge of protein structures and enhancing understanding of various diseases.

 

Work Content

- Preparation and purification of milligram quantities of stable isotope-labeled proteins and nucleic acids

- Investigating interactions between proteins and between proteins and nucleic acids in vitro using various biophysical methods

- Using solid-state NMR rotors with different spinning speeds, including the smallest 0.7mm rotor that can reach 111kHz, for magic angle spinning

- Obtaining high-resolution structural details and interaction information of these molecules through NMR spectroscopy
