Research Interests

The research of our group has focused on the three dimensional structures of proteins and their structure-function relationships and the protein engineering of for a rather long time. Previous research subjects included protein hormones, polypeptide neuron toxins, and some defense proteins with antifungal, antiviral, and antitumor activities. It has participated in the structural analysis of pig insulin, the first proteins to be studied by crystallography in China. The major research achivements were received two Second Prizes of the National Natural Science Award of China and one First Prize of the Science Progress Award of the Chinese Academy of Sciences.

The current research interest of the group is on the structural biology of pathogenesis, especially the structure-function relationships and molecular mechanisms of proteins involved in diseases caused by both exogenous factors (such as infections by pathogenic microbes) and endogenous factors (such as naturally occurred mutations). The studies are essential for illustrating the mechanisms of the onset and defense of relative diseases and providing accurate knowledge and new idea to disease prevention and drug design. Our resent research are focused on the following three subjects:

1. Critical pathogenic protein & complex from pathogenic microbes

a. Structural and mechanistic studies of proteins related to the infection, persistence, and drug resistance of Mycobacterium tuberculosis;

b. Structure-function relationship and pathogenic mechanism analyses of the effector proteins of Gram-negative bacteria, especially the virulence proteins from the Type III, IV and VI Secretion Systems of Shigellaflexneri, Helicobacter pylori and Pseudomonas aeruginosa, respectively;

2. The Protein structure-functional basis for some endogenous disease (gene mutation caused), including neurodegenerative disease Ataxia with Oculomotor Apraxia Type 1 (AOA1), Cerebral cavernous malformation (CCM).

3. Structural biology of pattern recognition receptors of pathogen-associated molecular patterns (PAMPs)

Toll-like receptors (TLR) and NOD-like receptors (NLR) are major functional proteins to recognize conserved PAMPs and initiate appropriate immunological signaling. We are concentrated on the recognition of lipopolysaccharides from pathogen by human TLR1/TLR2/TLR6, to uncover the mechanisms by which the lipopolysaccharides are recognized by different TLR heterodimers and initiate strong immunological responses. We are also investigating the structures of NLR using combined technologies of X-ray crystallography and EM.
