vesicular neurotransmitter transport proteins

Summary

Summary: A family of neurotransmitter transporter proteins that are INTEGRAL MEMBRANE PROTEINS of the LIPID BILAYER of SECRETORY VESICLES. They are ANTIPORTERS that exchange vesicular PROTONS for cytoplasmic NEUROTRANSMITTER and play an essential role in regulating neurotransmission.

    ..Taken together, data presented here show that average extracellular dopamine in the NAc is low (20-30?nM) and largely arises from phasic dopamine transients. ..

    ..We conclude that BDNF increases mEPSC frequency by boosting vesicular fusion through a presynaptic, Ca(2+)-dependent mechanism involving TrkB receptors, Ca(2+) stores, and TRPC channels. ..

    ..In conclusion, distinct vesicular transporters show a variable degree of colocalization with synapsin proteins and, hence, distinct sensitivities to inactivation of the genes encoding synapsin I and II. ..

    ..Together, these results suggest that arl-8 promotes a trafficking identity for presynaptic cargoes, facilitating their efficient transport by repressing premature self-association. ..
