Abstract

Synaptic vesicles can be coated in vitro in a reaction that is ARF-, ATP-, and temperature-dependent and requires synaptic vesicle membrane proteins. The coat is largely made up of the heterotetrameric complex, adaptor protein 3, recently implicated in Golgito-vacuole traffic in yeast. Depletion of AP3 from brain cytosol inhibits small vesicle formation from PC12 endosomes in vitro. Budding from washed membranes can be reconstituted with purified AP3 and recombinant ARF1. We conclude that AP3 coating is involved in at least one pathway of small vesicle formation from endosomes.
