Cryptic cysteines
WebThese modulatory effects are specific to cryptic cysteines that only become exposed under strain. Relevant to the many proteins that function under mechanical force, this mechanism provides a way to dynamically adjust protein and tissue elasticity. WebFeb 20, 2024 · The temporal separation of redox-independent and redox-dependent events plays a key role in specifying which cysteines are oxidized by EGF due to an emerging relationship between protein structure and oxidation of cryptic cysteines, those that are only solvent exposed upon changes in protein conformation (6, 15, 75, 86).

Upon … 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.
