TLDR
A variety of proteins, including transcription factors, molecular chaperones and protein tyrosine phosphatases, are regulated via redox processes, and common mechanisms underlie the sensitivity of cysteines to redox, such as proximity to polar and charged groups.

A dynamic pathway for calcium-independent activation of CaMKII by methionine oxidation

TL;DR: It is shown that oxidation of paired regulatory domain methionine residues sustains CaMKII activity in the absence of Ca2+/CaM and highlights the critical importance of oxidation-dependent CaMK II activation to AngII and ischemic myocardial apoptosis.

Hydrogen peroxide: a Jekyll and Hyde signalling molecule

TL;DR: This work examines the factors and circumstances that determine whether H2O2 acts in a pro-survival or deleterious manner, and reveals that the diverse functions of ROS can be determined by the subcellular source, location and duration of these molecules within the cell.

Peroxiredoxin Evolution and the Regulation of Hydrogen Peroxide Signaling

TL;DR: It is suggested that this adaptation allows 2-Cys Prxs to act as floodgates, keeping resting levels of hydrogen peroxide low, while permitting higher levels during signal transduction, and is proposed to be the structural origins of sensitivity.

Epidermal Growth Factor (EGF)-induced Generation of Hydrogen Peroxide ROLE IN EGF RECEPTOR-MEDIATED TYROSINE PHOSPHORYLATION

TL;DR: In this paper, the role of reactive oxygen species (ROS) in epidermal growth factor (EGF) signaling was investigated, and the dependence of H2O2 production on the intrinsic tyrosine kinase activity of the EGF receptor and the autophosphorylation sites located in its COOH-terminal tail was investigated.
