WebNov 15, 2002 · ER stress, nutrient deprivation, oxidative stress, and hibernation are all associated with elevated eIF2α phosphorylation. The first two activate known eIF2α kinases, whereas the others act through unknown mechanisms. Phosphorylation of this factor inhibits translation of most mRNAs, leading to a decline in protein synthesis rates. WebA great variety of conditions and pharmacological compounds can disturb ER homeostasis, leading to ER stress and the accumulation of unfolded and misfolded proteins. In response, ER stress signaling pathways stimulate pro-survival efforts to either neutralize the stressful insult or adapt to it.
