Protein Folding Youtube A newly synthesized protein entering the endoplasmic reticulum (er) undergoes a series of modifications and encounters a number of molecular chaperones and folding enzymes that all together assist its proper folding and subsequent release from the er. the majority of resident er proteins are dedicated to the folding process. The assembly of multisubunit proteins and the refolding of polypeptides are similar in their use of chaperone proteins that help prevent premature folding, sequestering parts of the protein from h bonding interaction until the full protein is in the er lumen. figure 11.3.10 11.3. 10. protein folding is optimized in the er. On acute er stress, the upr is activated to restore er protein folding homeostasis. this involves the transient attenuation of protein synthesis, an increase in protein folding and transport in. The upr regulates protein trafficking into and out of the er in response to environmental stress signals and or mutations that may increase the load of unfolded or aberrant proteins in the er lumen. 159, 216 minimally, in yeast cells the upr is a signaling cascade that up regulates genes encoding factors involved in protein folding, erad and trafficking through the secretory pathway. 217, 218.
