Which statement below regarding endoplasmic reticulum (ER)-transport is NOT correct?

ER resident proteins that escape from the ER can be returned by vesicular transport.

All proteins within the ER lumen freely diffuse and end up in transport vesicles by random.

Proteins can be transported from the ER to the Golgi apparatus via COPII-coated transport vesicles.

After budding from the ER, vesicles may fuse together via SNARE-mediated homotypic fusion.
