Vesicles coalesce toform new cis Golgi cisternae Vesicles also
transport certainproteins back to ER
Vesicles movefrom ER to Golgi
Vesicles transport specificproteins backward to newerGolgi cisternae
Cisternalmaturation:Golgi cisternaemove in a cis-to-transdirection
Vesicles form andleave Golgi, carryingspecific proteins toother locations or tothe plasma mem-brane for secretion
