Only native polypeptides are released from the endoplasmic reticulum (ER) to be transported at the site of activity. Persistently misfolded proteins are retained and eventually selected for ER-associated degradation (ERAD). The paradox of a structure- based protein quality control is that functional polypeptides may be destroyed if they are architecturally unfit. This has health-threatening...
