Dual oxidases (DUOXs) are Ca(2+)-activated NOXs and operate as H(2)O(2)-generators in various tissues. A tight regulation is however required to avoid ROS overproduction that can rapidly be harmful to biological systems. DUOX activator (DUOXA) proteins act as organizing elements for surface expression and activity of the DUOX enzymes. To study DUOX activation by the maturation factors, chimeric DUOXA proteins were generated by replacing particular domains between DUOXA1 and DUOXA2. Their impact on DUOX function and membrane expression were explored in a reconstituted heterologous cell system composed of COS-7 cells. We have shown that the COOH-terminal end of DUOXA1 is responsible for DUOX1-dependent H(2)O(2) generation. The NH(2)-terminal tail of DUOXA2 is critical to specify the type of ROS released by DUOX2, hydrogen peroxide or superoxide. Native DUOXA2 would constrain DUOX2 to produce H(2)O(2). However, alterations of the DUOXA2 NH(2)-terminal domain modify DUOX2 activity triggering superoxide leaking. Our results demonstrate that specific domains of the DUOX maturation factors promote the activation of DUOXs as well as the type of ROS generated by the oxidases."xsd:string |
