Module 4: Figure early endosome budding

Early endosome budding.

One of the functions of the early endosome is to recycle various membrane proteins such as the transferrin receptor (TFR) back to the plasma membrane. These proteins are either returned directly to the plasma membrane or they are recycled via the recycling endosome (See Module 4: Figure membrane and protein trafficking). In both cases, the proteins are sorted at tubular extension before being budded off into vesicles that are carried away by various motor proteins.
