WebIn specialist secretory cells the Golgi complex is responsible for the sorting and packing of such well-known items as insulin, digestive enzymes and pectin. The Golgi apparatus produces specialist vesicles or vessels for the transport of its products. Some of these have special wrappings or coatings that help identify the contents. WebKDEL receptor (KDELR) is a key protein that recycles escaped ER resident proteins from the Golgi apparatus back to the ER and maintains a dynamic balance between these two organelles in the early secretory pathway. Studies have shown that this retrograde transport pathway is partly regulated by two …
