It has been known that reactive oxygen species (ROS) control the enzymatic and transcriptional activity of proteins via direct modification of cysteine residues. Hence, oxidation of cysteine thiol could be a vital modulator of signal transduction pathways. These findings indicate that some proteins serve as the sensor proteins highly sensitive to ROS. In this review, I show the relationship between intracellular ROS sensor and the regulation of protein function via oxidation.
