The mechanisms of COPI vesicle uncoating are not well established (reviewed in Szul and Sztul, 2011). Coat dissociation may be promoted by changes in protein-protein interactions upon vesicle tethering, as has been suggested for retrograde COPI-traffic to the ER (Zink et al, 2009). After uncoating and membrane fusion, the SNARE complex exists as a four-helix bundle that must be "unzipped" (dissociated) by NSF for reuse, an energetically costly event (reviewed in Hong and Lev, 2014; Sudhof and Rothman, 2009).
