CFTR protein contains

a di-acidic sorting signal that binds to the Sec24 subunit

of the COPII vesicle coat and is necessary for transport of

the CFTR protein out of the ER.

Most common CFTR mutation is a ΔF508 -

Prevents normal transport of CFTR to the plasma membrane by blocking its packaging into COPII vesicles budding from the ER. 

Change the conformation of the cytosolic portion of CFTR so that the signal is unable to bind to Sec24.
