How are proteins transported out of the endoplasmic reticulum to the golgi apparatus?
Answers
Proteins Transportation
Correctly folded and assembled proteins in the ER are packaged into COPII-coated transport vesicles that pinch off from the ER membrane. ... The Golgi apparatus distributes the many proteins and lipids that it receives from the ER and then modifies the plasma membrane, lysosomes, and secretory vesicles.
The protein transports from the ER to the Golgi apparatus by passing via a series of compartments. The transfer from one to the other compartment is based on a delicate balance between the backward and forward transport pathways.
A few vesicles will select cargo molecules and transport them to the next compartment , whereas other vesicles retrieve the escaped proteins in order to return them to the previous compartment for their continuity of normal function.
