Vesicular transport protein
From Wikipedia, the free encyclopedia
A vesicular transport protein is a transmembrane or membrane associated protein. It regulates or facilitates the movement by vesicles of the contents of the cell.[1]

[edit] Types
Examples include:
- Archain
- ARFs
- Clathrin
- Caveolin
- Dynamin and related proteins, such as the EHD protein family
- Rab proteins
- SNAREs
- Sorting nexins
- Synaptotagmin
- TRAPP complex
[edit] Pathways
There are multiple pathways, each using its own coat and GTPase.[2]
- 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)
