ROS as signaling molecules

Besides their role as mediators of oxidative modifications of cell constituents, ROS can also function as signaling molecules, even at very low concentrations.13 Some examples of this type of response are ROS activation of neutral sphingomyelinase leading to ceramide formation, and modulation by ROS of several kinases or transcription factors controlling the cell cycle.14,15 One mechanism by which ROS transmit signals is by oxidation of thiol residues in cysteines of the target proteins to sulfenic acids. This transformation serves as a chemical switch that can either activate or deactivate the protein function.
