WANG Chu
Professor, College of Chemistry and Molecular Engineering, Peking University

Brief bio: Wang Chu, Professor, College of Chemistry and Molecular Engineering, Peking University. Dr. Wang received Ph.D. in 2007 from the University of Washington under the guidance of Prof. David Baker, training in the area of computational protein structural prediction and design. He then worked as a postdoctoral fellow with Prof. Benjamin Cravatt at Scripps Research Lo Jolla, and developed multiple chemical proteomic methods to profile reactive cysteines and modifications in proteomes. In 2014, he joined Peking University to start his independent career and was promoted to Tenured Professor of Chemical Biology in 2020. He has won the Young Chemical Biologist Award from the International Chemical Biology Society and the Distinguished Young Scholar Award from the National Natural Science Foundation of China. His research interest is to develop chemical and computational proteomics methods to enable quantitative profiling of functional enzymes, protein post-translational modifications as well as protein-ligand interactions in proteomes.

Topic: Chemical Proteomic Profiling of Functional Modifications by Reactive Metabolites

Abstract: Genome sequencing projects have revolutionized our view of the complexity of prokaryotic and eukaryotic proteomes, however, we are also left with a daunting challenge of functionally annotating these large number of predicted proteins. Chemical proteomic methods, such as activity-based protein profiling (ABPP), have been developed aiming at systematically discovering new functional targets directly from native proteomes. In this talk, I will present recent progresses from my laboratory which combines ABPP-based chemical proteomic, biochemical, and computational strategies to uncover functional sites of post-translational modifications by reactive metabolites in proteomes.

CHEN Peng
Professor, Chair Department of Chemical Biology, College of Chemistry and Molecular Engineering, Peking University

Brief bio: Dr. CHEN Peng obtained a BS degree in Chemistry at Peking University in 2002, and a Ph.D. in Chemistry with Prof. HE Chuan at The University of Chicago in 2007. After a postdoctoral training at The Scripps Research Institute with Prof, Peter SCHULTZ, he started his independent career at Peking University in 2009. He is currently the Director of the Chemical Biology Division at the Chinese Chemical Society and the Executive Editor of ACS Chemical Biology. His research interest is at the interface of Chemistry and Biology.

His lab is a leading group in developing bioorthogonal cleavage reactions for chemically controlled protein activation and profiling in living systems. This has created a new direction in bioorthogonal chemistry for the gain-of-function study of proteins under living conditions. He employed this toolkit to study how the spatial-temporal organized human proteome is rewired during cancer and immune signaling, and his lab also exploited the potential of these new reactions in protein-based therapy.

Topic: Bioorthogonal Cleavage Chemistry for Protein Activation in Space and Time

Abstract: Employing small molecules or other chemical means to modulate the function of an intracellular protein of interest, particularly in a gain-of-function fashion, remains highly desired but challenging. In this talk, I will introduce a "genetically encoded chemical decaging" strategy that relies on our recently developed bioorthogonal cleavage reactions to control protein activation in living systems. These reactions exhibit high efficiency and low toxicity for decaging the chemically "masked" lysine or tyrosine residues on intracellular proteins, allowing the gain-of-function study of individual enzymes within living cells and mice. Most recently, with the assistance of computer-based design and screening, we further expanded our method from "precise decaging" of enzyme active-sites to "proximal decaging" of enzyme pockets. This new method, termed Computationally Aided and Genetically Encoded Proximal Decaging" (CAGE-prox) (CAGE-prox), showed general applicability for switching on the activity of a broad range of proteins under living conditions. I will end by showcasing exciting applications of our CAGE-prox technique on: i) constructing orthogonal and mutually exclusive kinase signaling cascades; ii) temporal caspase activation for time-resolved profiling of proteolytic events upon apoptosis; and iii) on-demand activation of bacterial effectors as potential protein prodrugs for cancer therapy. Finally, by coupling with the proximity-labeling enzymes that have been used for subcellular targeting, we further developed a spatial-temporal resolved proteomics strategy for subcellular proteome profiling in living cells.

Yimon AYE
Associate Professor, Swiss Federal Institute of Technology Lausanne

Brief bio: Aye received her combined B.S. & M.S. degree in Chemistry at the University of Oxford, UK, in 2004, and Ph.D. degree in Organic Chemistry with Prof. David Evans from Harvard University, in 2009. She then switched her research discipline to life science and trained with Prof. JoAnne Stubbe at MIT. Science in the Aye lab (https://leago.epfl.ch) – established in mid-2012 –seeks to understand non-canonical cell signaling processes. Her laboratory is most well-known for investigations into electrophile signaling, a nuanced communication mode whereby on-target engagement between reactive metabolites and target proteins, orchestrates precision responses at cellular/organismal levels. Contributions from here laboratory have been recognized by several international honors, with the most recent being the 2021 ACS Cope Scholars, International Chemical Biology Society Global Lectureship, 2022 Tetrahedron Young Investigator, and European Research Council grant awards.

Topic: What We Do in the Dark: Illuminating Functional Responsivity, Signaling Activity, & Druggability of the Local Interactome in Living Systems

Abstract : Prof. Yimon Aye will highlight how an organic chemistry-driven idea has evolved into an enabling chemical biology toolset that can address some of the long-standing as well as emerging key biomedical problems of importance in both fundamental research and translational science. Focus will be placed on our latest understanding of precision electrophile signaling mechanisms and how such precision localized electrophile delivery concept and associated tools open up new opportunities to simultaneously map and functionally validate our localized protein players and pathways in a chemical-function-guided manner, in the context of functional drug discovery and mode-of-action deconvolution.

John ZHANG
COO, EVP, Cheerland Biotechnology Co., Ltd.

Brief bio: Dr. John Zhang earned his Ph.D. degree in the United States from EVMS and continued on two consecutive postdoctoral trainings for an additional five years at The Johns Hopkins University School of Medicine in Molecular Biology and OSU in Molecular Virology, respectively. Currently, he is a Chief Operation Officer and Executive Vice President at Cheerland Precision Medicine Group. Dr. Zhang returned to work in China in 2016 and served as a vice president of manufacturing operation and process development at Qilu Pharmaceutical followed by working as VP at BeiGene and Zai Lab Incorporations in charge of Manufacturing & Process technology development. Before returning to China, he worked for Lonza Biologics in the US engaging in PC/PV studies & supporting 20k-L bioreactor manufacturing operation, and for Bio-Techne group in charge of manufacturing operation. Dr. Zhang has more than 25 years of experience in both basic research at the University of Illinois at Chicago as an Assistant Professor for 7 years and biologics drug development in pharmaceuticals in the last 14 years. He has also published more than 25 peer-reviewed papers in journals and developed a few commercialized biologics products in the US.
