Transport Vesicle

Endomembrane system member employed for moving materials, including membrane, to and from the Golgi apparatus.

A special as well as notable type of transport vesicle is the secretory vesicle, which transports materials from the Golgi apparatus to the plasma membrane, thereby releasing their contents into the extracellular environment, such as in terms of the release of neurotransmitters. More generally, any endomembrane system member that possesses membrane proteins or proteins in their lumens are supplied with those proteins by vesicles that transport them from the Golgi.

Movement of materials from the endoplasmic reticulum, notably the rough endoplasmic reticulum, is to the Golgi apparatus. This movement, too, occurs within the context of transport vesicles, in this case that move from the endoplasmic reticulum to form the cis face of the Golgi.
