Peroxiporins : Redox Signal Mediators In And Between Cells (Original PDF From Publisher)

Written by Iria Medraño-Fernandez

Aerobic organisms convert oxygen molecules into water in order to produce energy. Reactive oxygen species (ROS), a collective term for the harmful radical intermediates produced by this reductive process. Ironically, the creation of potentially harmful species is a byproduct of these physiological processes. This seeming drawback has been transformed by evolution into a channel for information transmission.

Redox signalling is therefore a very efficient and well-organized process inside the cell. The actual physical division of sources and targets into distinct cell compartments is a crucial component of its control. Peroxiporins are proteins that transport H2O2 across cellular membranes and facilitate the distribution of signals from emitters to receptors. As a result, these channels are placed carefully to ensure appropriate but secure signalling in the narrow space between life and death.
