What are clathrin, copi and copii types of?

• Correct Answer: vesicle coats
• artery coats
• replication coats
• pathogen coats

Explanation: The vesicle coat selects specific proteins as cargo. It selects cargo proteins by binding to sorting signals. These complexes cluster in the membrane, forming a vesicle buds, or coated pit . There are three types of vesicle coats: clathrin , COPI and COPII. Clathrin coats are found on vesicles trafficking between the Golgi and plasma membrane, the Golgi and endosomes, and the plasma membrane and endosomes. COPI ( coat protein complex) coated vesicles are responsible for transport from the cis -Golgi to the ER (retrograde transport), while COPII coated vesicles are responsible for transport from the ER to the Golgi (anterograde transport). Low-density lipoprotein (LDL) receptors aggregate in clathrin coated pits prior to internalization.
