Golgi Apparatus

ID #1868

If a protein's final destination/ work place is in the ER does it need to travel to the trans face of the golgi, or is the retrograde transport only occur from the cis face?

It ultimately depends on how much additional processing is necessary once it gets to the Golgi, but my impression is that ER proteins don't need much processing and won't make it all the way to the trans-Golgi to be sent back to the ER.
