    Highlights •The ER stress sensor IRE-1 has a distinct function in cytoplasmic homeostasis •Local redox signals block IRE-1 ER signaling by sulfenylating a kinase cysteine •This functional switch initiates the p38/SKN-1(Nrf2) antioxidant response at IRE-1 •The IRE-1 paradigm implies broad and versatile functions for signaling at cysteines

    Reactive oxygen species (ROS) sometimes can aid in maintaining health – findings now boosted by a surprising discovery from the researchers. In other circumstances, high levels of reactive forms of oxygen can damage proteins and contribute to diabetic complications and many other diseases.
