ProteomicsChemoproteomic Profiling by Cysteine Fluoroalkylation Reveals the DNA Repair Protein XRCC5 as a Functional Target of Myrocin G
Chemoproteomic profiling of cysteines has emerged as a powerful method for screening the proteome-wide targets of cysteine-reactive frag-ments, drugs and natural products. Herein, we report the development and an in-depth evaluation of a tetrafluoroalkyl benziodoxole as a cyste-ine-selective chemopr...

ProteomicsEthynylation of Cysteines from Peptides to Proteins in Living Cells
Efficient methods to introduce bioorthogonal groups, such as terminal alkynes, into biomolecules are important tools for chemical biology. State-of-the-art approaches are based on the introduction of a linker between the targeted amino acid and the alkyne, and still present limitations of either rea...

ProteomicsMixed Alkyl/Aryl Phosphonates Identify Metabolic Serine Hydrolases as Antimalarial Targets
Malaria, caused by Plasmodium falciparum, remains a significant health burden. The barrier for developing anti-malarial drugs is the ability of the parasite to rapidly generate resistance. We previously demonstrated that Salinipostin A (SalA), a natural product, potently kills parasites by inhibitin...

ProteomicsUnveiling Cellular Communications through Rapid Pan-Membrane-Protein Labeling
The dynamic protein distribution within and across the plasma membrane is pivotal in regulating cell communications. Yet, methods facilitating rapid labeling, applicable across diverse cell types, and amenable to multiplexed live imaging are scarce. We discovered that live mammalian cell surface pro...

Proteomics1-deoxydihydroceramide causes anoxic death by impairing chaperonin-mediated protein folding
Ischemic heart disease and stroke are the most common causes of death world-wide. In both pathologies anoxia, the lack of oxygen, triggers profound metabolic and cellular changes. Sphingolipids have been implicated in anoxia injury, but the pathomechanism is unknown. Here we show that injury is caus...
