The Carroll lab has an established record of attacking fundamental problems in redox biology through a powerful, interdisciplinary approach that integrates synthetic chemistry with proteomics, biochemistry, and cell biology. An overarching goal of our research program is to understand the biological chemistry and molecular mechanisms of redox-based cellular regulation and signal transduction, with particular emphasis on the role of cysteine oxidation, a ubiquitous and conserved mechanism for controlling protein function. We are also exploring the therapeutic potential of redox-regulated protein function by developing an entirely new class of inhibitors that targets oxidized cysteine residues of key proteins involved in human disease. Ultimately, our goal is to accelerate the discovery of key regulatory nodes of redox-signaling networks, profile changes in protein cysteine oxidation associated with disease, and harness this information for the development of new diagnostic and therapeutic approaches.
