Webb15 aug. 2008 · Many diseases are caused by defects in protein trafficking. Protein trafficking diseases occur when a mutant protein is recognized by the endoplasmic reticulum (ER) quality control system (ERQC), retained in the ER, and degraded in the cytosol by the proteasome rather than being trafficked to its correct site of action.

Webb24 dec. 2024 · The term protein trafficking describes the shuttling of proteins into and out of cells, and between different subcellular compartments. It is essential to cell function and growth, and its dysregulation has been linked to conditions including cancer, cystic fibrosis, and various neurodegenerative disorders. Webb9 mars 2014 · Membrane trafficking functions in the delivery of proteins that are newly synthesized in the endoplasmic reticulum (ER) to their final destinations, such as the plasma membrane (PM) and the vacuole, and in the internalization of extracellular components or PM-associated proteins for recycling or degradative regulation.
