<front><div type="abstract" xml:lang="en"><p><bold>Background:</bold>
α-Synuclein is known to undergo exchange between membrane and cytosolic compartments.</p>
<p><bold>Results:</bold>
α-Synuclein interacts with GTP-bound Rab3a on synaptic vesicles, and its dissociation is mediated by GDI/Hsp90.</p>
<p><bold>Conclusion:</bold>
α-Synuclein's membrane association and dissociation cycle is linked to synaptic activity by the Rab3a recycling machinery.</p>
<p><bold>Significance:</bold>
Significance: Impairments to α-synuclein interactions with vesicles and with the Rab3a recycling machinery may affect neurodegeneration.</p>
