May play a role in regulated exocytosis. May indirectly regulate the activity of the plasma membrane dopamine transporter SLC6A3 and thereby regulate dopamine transport back from the synaptic cleft into the presynaptic terminal.
Subcellular locations: Cytoplasmic vesicle, Secretory vesicle, Synaptic vesicle membrane, Synapse
Found at the neuromuscular synapses.
