    basic FUNCTION
  • involved in the ATP-dependent vesicular transport of biogenic amine neurotransmitters
  • essential for loading monoamines into vesicles and maintaining normal neurotransmission
  • regulates neurotransmission and reduces cytosolic toxicity of monoamines
  • sequesters cytoplasmic dopamine into synaptic vesicles for storage and release
  • during the stimulus, the endocytosis of VMAT2 (but not VGLUT1) accelerates dramatically in midbrain dopamine but not hippocampal neurons, indicating a novel, cell-specific mechanism to sustain high rates of release
