The major histocompatibility complex class I (MHC-I) antigen presentation pathways play pivotal roles in orchestrating immune responses. Recent studies have begun to utilize cysteines within the immunopeptidome for therapeutic applications, such as using covalent ligands to create haptenated neoanti...
Cysteine residues undergo various oxidative modifications, acting as key sensors of reactive oxygen species (ROS) and reactive nitrogen species (RNS). Given that ROS and RNS have known roles in many pathophysiological processes, numerous proteome-wide strategies to profile cysteine oxidation state h...
Current methods for measuring amino-acid side-chain reactivity lack the throughput needed to screen large chemical libraries for interactions across the proteome. Here we redesigned the workflow for activity-based protein profiling of reactive cysteine residues by using a smaller desthiobiotin-based...

Oxidation products of 1-palmitoyl-2-arachidonoyl-sn-glycerol-2-phosphatidylcholine (PAPC), referred to as OxPAPC, accumulate in atherosclerotic lesions and regulate over 1000 genes in human aortic endothelial cells (HAEC). We previously demonstrated that OxPAPC covalently binds to a number of prote...
With the idea of exploiting metal-templated reactions to achieve selective modification of cysteines in proteins for antibacterial applications, an organometallic cyclometalated Au(III) compound was explored in a competitive chemoproteomic approach based on the isoDTB-ABPP (isotopically labelled des...
