Every living cell in our body is composed of hundreds of thousands of proteins that are required to control diverse cellular functions and thus fundamentally important to our life. The broad research interest of Dr. Jun Qin is to understand the molecular principles of how proteins transmit information within or across cells to the control various cellular functions. In particular, his laboratory has been focusing on studying how a group of proteins, e.g., integrins, control cell adhesion - a fundamental process essential for almost every aspect of life such as embryonic development, blood clotting, and tissue regeneration. By using state-of-the-art high resolution imaging techniques such as NMR spectroscopy and crystallography, Qin laboraotry solved 3D atomic-level structures of a series of cell adhesion proteins and protein complexes. These structures, combined with further structure-based mutational/functional analyses, resolved some longstanding puzzles of cell adhesion biology and thus significantly advanced the field. In collaboration with other researchers including clinicians, Qin laboratory also pursues the structure-based design of drugs that target some crucial yet dysregulated proteins in diseases. With these state-of-the-art approaches, Dr Qin hopes to not only advance the fundamental understanding of cell adhesion and other biological processes but also impact on patient care by accelerating the discovery and development of novel therapeutics to treat relevant diseases such as heart failure, diabetes, and cancer.
Dr. Jun Qin is full staff in department of Cardiovascular & Metabolic Sciences. He also holds professorship in lerner college of medicine and departments of biochemistry and pharmacology, Case Western Reserve University. Specializing in structural and molecular biology, Dr Qin has had a longstanding track record in studyin mechanisms of cellular signal transduction via protein-protein interactions and is especially known in the area of integrin-mediated cell adhesion and signaling. Dr Qin's research has been continously funded by National Institutes of Health (NIH) over the past two decades. His work is highly cited, which has made seminal contributions to the basic mechanisms of cell signaling as well as to the understanding and drug development of various human diseases such as thrombosis, diabetes, and cancer. He is currently Bonnie & Eunice Collins endowed chair for innovative diabetes research.
Dr Qin is an elected fellow of American Association for the Advancement of Science due to his significant contribution to the mechanisic understanding of cell signaling. He has served as reviewers or board members for many journals and funding agencies and has given hundreds of invited talks in institutions and conferences. He has received numbous awards such as Maria and Sam Miller Professional Excellence Award in Basic Science, Cleveland Clinic and Cleveland Clinic Innovator Award.
Dr Qin received his Ph.D from University of California Davis in 1992 and completed his postdoctoral training in National Institute of Diabetes and Digestive and Kidney Diseases in 1996.

Every living cell in our body is composed of hundreds of thousands of proteins. These proteins are highly coordinated in their functions for regulating diverse cellular processes and thus fundamental to our life. The broad theme of our research is to understand the molecular basis of some key protein-protein interactions in transducing cellular information (cell signaling) and their dysfunctions in human diseases such as heart failure, diabetes, and cancer. To this end, we have been focusing on a class of cell surface receptors, integrins, and their associated proteins. Integrins are major components of cell-extracellular matrix (ECM) adhesion, cell morphology, and cell motility. Using structural biology techniques, including NMR spectroscopy and crystallography, we aim to build a three dimensional atomic level landscape of integrin-mediated protein interaction network to gain thorough understanding of integrin signaling. Our work so far has significantly advanced the field by building key parts of this landscape, which provided important mechanistic insight into the mechanisms of integrin signaling. In collaboration with a group of cell biologists and clinical scientists, we also investigate other important cellular signaling pathways and their dysregulations. We have been able to link our recent atomic level findings to the pathogenesis of several human disorders with exciting identification of several potential protein inhibitors for these disorders. Our studies may ultimately help develop better approaches for diagnosing and treating the relevant human diseases.
