Vesicular transport protein

A vesicular transport protein, or vesicular transporter, is a membrane protein that regulates or facilitates the movement of specific molecules across a vesicle's membrane. As a result, vesicular transporters govern the concentration of molecules within a vesicle.

Types
Examples include:
 * Archain
 * ARFs
 * Clathrin
 * Caveolin
 * Dynamin and related proteins, such as the EHD protein family
 * Rab proteins
 * SNAREs
 * Vesicular transport adaptor proteins e.g. Sorting nexins
 * Synaptotagmin
 * TRAPP complex
 * Synaptophysin
 * Auxilin

Pathways
There are multiple pathways, each using its own coat and GTPase.


 * COP 1 (Cytosolic coat protein complex ) : retrograde transport; Golgi > Endoplasmic reticulum
 * COP 2 (Cytosolic coat protein complex ) : anterograde transport; RER -> cis-Golgi
 * Clathrin : trans-Golgi > Lysosomes, Plasma membrane > Endosomes (receptor-mediated endocytosis)
