Identifying particular functions has required laborious individual … WebJul 10, 2024 · Since NLRP3 and noncanonical inflammasome activation are amplified by cellular oxidative stress 16 – 22, these redox-sensitive reactive cysteine residues may regulate inflammation endogenously, and compounds that covalently modify reactive cysteines may inhibit inflammation by acting at multiple steps.
Web2 days ago · The accumulation of reactive oxygen species (ROS) initiates oxidative stress that causes oxidation of cysteine residues in proteins. Recently, the critical roles of reactive sulfur species (RSS), such as cysteine hydropersulfide, that protect proteins from irreversible oxidation are highlighted ( 19 ). WebIn addition, we created a resource of cysteine reactivity to 285 electrophiles in three human cell lines, which includes >20,000 cysteines from >6,000 proteins per line. The goal of proteome-wide profiling of cysteine reactivity across thousand-member libraries under several cellular contexts is now within reach. Data Access and Information
