The transport of neurotransmitters into synaptic vesicles.
As investigations identify additional plasma membrane neurotransmitter transporters, attention has focused on the molecular basis of neurotransmitter transport into synaptic vesicles. The transport of biogenic amines into chromaffin granules has served as the paradigm for understanding vesicular transport. Recent work now describes the vesicular transport of other classical neurotransmitters, which occur by distinct but related mechanisms. To determine their biochemical basis, several of the transporters have been functionally reconstituted in liposomes. The ability of vesicular amine transport to protect against the neurotoxin MPP+ has permitted the isolation of the first cDNA clone for a member of this family, and the sequence establishes a relationship with drug-resistance transporters in bacteria.
