Cryptic cysteines

WebApr 30, 2024 · Many redox regulated cysteines are cryptic and solvent exposed by changes in protein structure that were induced by EGF treatment. The novel finding that cryptic cysteines are redox regulated has important implications for how redox signaling networks are specified and regulated to minimize crosstalk. WebOur Research 1 Cryptic Cysteines, Redox Signaling, & Protein Structure Dynamics We are interested how redox signaling depends on regulation of protein structure and cysteine solvent accessibility. We've shown this specifies redox signaling networks and think it has implications for understanding protein structure dynamics more broadly.
