WebDec 22, 2011 · COPII-coated vesicles are formed and bud at specific locations on the ER membrane named ER-exit sites (ERESs) 2,3. COPII coat assembly begins with the recruitment of the small GTPase Sar1 to the ER. We would like to show you a description here but the site won’t allow us. WebCOPI and COPII are vesicle coat complexes whose assembly is regulated by the ARF1 and Sar1 GTPases, respectively. We show that COPI and COPII coat complexes are recruited separately and independently to ER (COPII), pre-Golgi (COPI, COPII), and Golgi (COPI) membranes of mammalian cells.
