Research Summary

Fueled by the ever-growing DNA sequence information, the field of proteomics has become one of the most important disciplines to characterize protein function and activity and provide insight into functional networks on a global scale. Emerging evidences suggest that proteins rarely act as single, isolated species when performing their function in vivo; they normally associate with other proteins and/or molecules as complexes and function in a network mode. The goals of my laboratory are to discover and characterize the activities of large collections of proteins, to build signaling networks for better understanding the mechanisms of biological processes, and to identify biomarkers for important human diseases. More specifically, our group is interested in analyzing protein posttranslational modifications, identifying important components involved in various signaling networks, and host-pathogen interactions on the proteomics level.

To achieve the above goals we developed two key technologies: high-throughput protein purification (>4,000 proteins/day) and high-density protein microarrays/chip (>15,000 protein/slide). So far, we have fabricated proteome chips in the budding yeast, herpesviruses, and E. coli (K12). We are also currently working on building a focused protein chip in humans. Previously, we and others demonstrated that protein chips could be used to characterize various protein binding properties, including protein-protein, protein-DNA, protein-lipid, and protein-drug interactions, and to identify downstream targets of protein kinases. More recently, we and colleagues have made significant progress in expanding the application of protein chips in the following directions: 1) novel protein binding assays, such as RNA-protein, live cell-protein, and lectin-protein interactions, 2) novel enzymatic reactions including protein ubiquitination and acetylation, 3) human serum profiling, and 4) a novel approach in protein chip fabrication. The above new assays or approaches have been applied to investigate host-pathogen interactions, protein glycosylation, cell surface glycan profiles, a ubiquitin E3 enzyme in yeast, and biomarker identification in human inflammatory bowel diseases. Our recent progress has been highlighted in five publications. We strongly believe that the protein chip technologies are capable of accumulating massive amount of data to allow comprehensive and systematic analyses of complex eukaryotic proteomes.
