To properly perform their functions, epithelial cells must accurately sort proteins to each surface ... bulk resides within ...

In such cells, the plasma membrane is part of an extensive endomembrane ... and the proteins that are found in these membranes contain sorting signals, which are like molecular zip codes that ...

The recycling of plasma membrane proteins mostly occurs at early and recycling endosomes; their degradative sorting is achieved in intermediate/late endosomes, which are also called multivesicular ...

Exosome formation is a multistep process that begins with the inward budding of the plasma membrane to form early ... and the endosomal sorting complex required for transport (ESCRT).
