What happens during endoplasmic reticulum stress?
What happens during endoplasmic reticulum stress? ER stress occurs when the capacity of the ER to fold proteins becomes saturated. ER stress may be caused by factors that impair protein glycosylation or disulfide bond formation, or by overexpression of or mutations in proteins entering the secretory pathway. What is endoplasmic reticulum stress induced apoptosis? ER transmembrane receptors detect the onset of ER stress and initiate the unfolded protein response (UPR) to restore normal ER function. If the stress is prolonged, or the adaptive response fails, apoptotic cell death ensues. Does oxidative stress cause ER stress? As the protein folding process...
