Endoplasmic reticulum There is growing recognition of the important role that the endoplasmic reticulum (ER) palys in redox pathophysiology, summarized in another review 249 as: (i) ER enzymes, like ER oxidoreductin (Ero1) and its thiol redox partner protein disulfide isomerase (PDI), have a role in the generation of ROS, (ii) ER is responsible for the synthesis, maturation and post-translational modification (glycosylation, phosphorylation, oxidation) of p22phox and Nox, (iii) Nox activity is promoted by the interaction between Nox and the ER chaperone PDI, (iv) some Noxes, especially Nox4, are active in ER, (v) The communication between ER and mitochondria occurs through mitochondria-associated ER membranes, which facilitates the exchange of Ca 2+ and ROS between the compartments, and (vi) ER plays a critical role in redox protein folding and stress responses
