Question

Difference between cop1 and cop2 mediated vesicle transport

Answer 1

COPI is protein complex that covers vesicles sending proteins from the cis terminal of the Golgi apparatus back to endoplasmic reticulum (ER) where they were initially synthesized and between Golgi partitions.  

Transport of this type is known as retrograde transport in contrast to anterograde transport joined with the COPII protein.  

It refers to coat protein that starts the budding process on Golgi apparatus.  

COPII is type of vesicle coat protein that sends proteins from the endoplasmic reticulum to the Golgi apparatus.  

This process is called as anterograde transport which in contrast to retrograde transport joined with the COPI protein.  

"COPII" refers to a coat protein complex that forces the budding method.  

Coat has large protein subcomplexes that are made of 4 different protein subunits.

Answer 2

Cop1:

• Cop1 is complex protein that transfers the protein from cis terminal of the Golgi apparatus to the Endoplasmic reticulum where they are initially formed and between Golgi partitions.
• This is known as retrograde transport.

Cop 2:

• Cop 2 is a type of 'vesicle coat protein'. The function of cop 2 is to end protein from endoplasmic reticulum back to the 'Golgi apparatus'.
• This is known as anterograde transport.
• It helps to force the budding method and is made up of 4 different protein subunits.
