Research Interests
We are interested in studying 3D structures of proteins and their interactions with other proteins, nucleic acids, and small molecule ligands, using NMR spectroscopy along with other techniques in biochemistry and molecular biology, aiming to reveal protein structure-function relationship and molecular mechanisms for protein functions, including the roles of anti-tumor gene HREV-107 family proteins in cell death, the structural basis of bacterial nucleoid-associated proteins in transcription regulation, the function of pro-apoptotic protein Bcl-XL in autophagy, the mechanism of glutaredoxins in iron and oxygen sensing, and protein folding using SARS-CoV main protease as a model.
