Attacking the cancer surfaceome
University of California San Francisco


James A. Wells, Ph.D. is Professor at the Department of Pharmaceutical Chemistry, UCSF, USA. Wells’ group pioneered the engineering of proteins, antibodies, and small molecules that target catalytic, allosteric, and protein-protein interaction sites; and technologies including protein phage display, alanine-scanning, engineered proteases for improved hydrolysis, bioconjugations, N-terminomics,  disulfide “tethering” (a novel site-directed fragment based approach for drug discovery), and more recently an industrialized recombinant antibody production pipeline for the proteome. These lead to important new insights into protease mechanisms, growth factor signaling, hot-spots in protein-protein interfaces, role of caspases in biology, and more recently determining how cell surfaces change in health and disease. His team was integral to several protein products including Somavert for acromegaly, Avastin for cancer, Lifitegrast for dry eye disease, and engineered proteases sold by Pfizer, Genentech, Shire and Genencor, respectively. James A. Wells is an elected member of the US National Academy of Science, American Association of Arts and Science, and the National Academy of Inventors.
