Coatomer
The coatomer is a protein complex that coats membrane-bound transport vesicles. Three types of coatomers are known:
- COPI (retrograde transport from trans- Golgi apparatus to cis-Golgi and endoplasmic reticulum)
- COPII (anterograde transport from ER to the cis-Golgi)
- clathrin and its associated adaptins ( endocytosis from the plasma membrane, and trans-Golgi to lysosomes)
