Web25 Dec 2014 · Lipid composition could modulate protein folding in, or trafficking through, the ER, indirectly activating UPR transducers by changing the level of unfolded proteins. Changes in the lipid composition could, for example, perturb ER calcium homeostasis, inhibiting the function of calcium-dependent enzymes and chaperones. WebThe unfolded protein response is associated with many diseases, including cancer, metabolic diseases such as type II diabetes and fatty liver diseases, and neurodegenerative diseases, for example, Alzheimer's disease. The UPR is also activated by numerous toxic chemicals and modulates drug action.
