Which coat protein(s) would you expect to be recruited for vesicle formation by a KDEL receptor?

Question

Quizplus · Accepted Answer

The KDEL receptor retrieves ER-resident proteins that have escaped the ER by selectively binding to them via their KDEL sequences and recycling them back to the ER. The COPI coat protein complex is responsible for vesicle formation in retrograde transport from the Golgi to the ER, which is the direction the KDEL receptor is transporting cargo. Therefore, COPI is the most likely coat protein to be recruited for vesicle formation by a KDEL receptor.
