The heat shock protein Hsc70 and auxilin, a J-domain containing protein, are responsible for clathrin disassembly through an ATP-dependent reaction. This uncoating step may be a point in the pathway subject to regulation. This final step releases the vesicle from the clathrin cage. The vesicle still contatins a specific Vamp molecule, part of the targeting and fusion mechanism that delivers the vesicle to its ultimate destination. This vesicle also contains its cargo, membrane proteins embeded in the Golgi-associated vesicle membrane.
