WebIn Cell Biology (Third Edition), 2024. Stress Responses in the Endoplasmic Reticulum. Conditions that flood the ER with excess protein or result in accumulation of misfolded proteins trigger the unfolded protein response (UPR; Fig. 20.13).Essentially, any condition in which protein import exceeds the protein-folding capacity of the ER triggers the UPR: … WebThe endoplasmic reticulum (ER) unfolded protein response (UPR) is activated by biosynthetic stress and leads to a compensatory increase in ER function. The JNK and p38 MAPK signaling pathways control adaptive responses to intracellular and extracellular stresses, including environmental changes such as UV light, heat, and hyperosmotic ... cheap flights to niagara falls ontario
