Quick Facts
A transport vesicle is a vesicle, coated with clathrin or coat protein (COP), that carries substances between intracellular compartments (Dorland, 2011).
Structure and/or Key Feature(s)
Proteins synthesized by the endoplasmic reticulum are packaged into a transport vesicle. That transport vesicle then enters the “cis face” of the Golgi complex and the components or the products pass from one cisterna to the next via a chain of transport vesicles through the entire Golgi complex. They are then repackaged into a secretory vesicle at the “trans face” (Ross and Pawlina, 2006).
Anatomical Relations
Transport vesicles are located entering the “cis face” of the Golgi complex and between cisternae of the Golgi complex.
Function
Proteins synthesized by the endoplasmic reticulum are packaged into a transport vesicle. That transport vesicle then enters the “cis face” of the Golgi complex and the components or the products pass from one cisterna to the next via a chain of transport vesicles through the entire Golgi complex. They are then repackaged into a secretory vesicle at the “trans face” (Ross and Pawlina, 2006).
Some transport vesicles leave the “trans face” and distribute proteins to a number of intercellular destinations (Ross and Pawlina, 2006).
