RESEARCH INTERESTS:

Our research is devoted to develop and apply advanced proteomic technologies to decipher human diseases through a rational search for novel disease targets and medicines. Tandem affinity purification tags have been constructed and utilized to study proteins that are important to transcriptional and translational regulatory networks, DNA repair, and apoptotic pathway. To this end, we have studied Ku70 protein complex and identified several new partners in the nucleus that function in DNA repair and transcriptional regulation. More importantly, we have found that Ku70 played a key role in signal transduction and governed the master switch in apoptotic pathway in the cytoplasm.  Currently, we focus our efforts to understand the role of Ku70 in cancer development and other human diseases. Another theme of our research is directed to develop high sensitive structural based proteomic methodologies to elucidate the molecular machine operating inside the cell. We have developed a novel laser induced photochemical protein surface oxidation method to determine protein (or protein complex) solvent accessible surface. We are applying this technology to map sites of protein-protein, protein-DNA/RNA, and protein-drug interactions, and to study their binding kinetics.

In addition, we are developing cutting-edge top-down proteomic technologies based on LC-MS/MS and LTQ Orbitrap Mass Spectrometry. Protein functions are highly regulated by their post translational modifications such as phosphorylation, acetylation and methylation. These modifications are central to cellular signaling pathways and gene regulatory networks, and therefore important for cancer therapy and diagnostics. However, it is difficult to study these modifications using traditional biochemical methods. The top-down proteomic strategy will enable us to characterize and profile global protein post-translational modifications.
