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. WebDec 24, 2024 · Crystal structures of arsenic-bound p53 mutants reveal a cryptic allosteric site involving three arsenic-coordinating cysteines within the DNA-binding domain, distal to the zinc-binding site. Arsenic binding stabilizes the DNA-binding loop-sheet-helix motif alongside the overall β-sandwich fold, endowing p53 mutants with thermostability and ... canopy and stars gloucester

WebEGF specified the cryptic cysteine residues that became solvent exposed and redox regulated. Because proteins that are structurally regulated by different RTKs or cellular perturbations are largely unique, these findings suggest that solvent exposure and redox regulation of cryptic cysteine residues contextually delineate redox signaling networks. WebSep 9, 2024 · Since most cysteines are buried due to negative selection (101, 102), redox regulation of cryptic cysteines provides a plausible mechanism specifying the context-dependent selectivity of redox signaling pathways (Fig. 4). Additional connections between protein structure and cysteine oxidation are notable. WebTo distinguish the contribution of cryptic cysteines from that of cysteines that are normally exposed to the solvent, we incubated the … flair flight credit
