Summary: Enables neurotransmitter transmembrane transporter activity. Involved in several processes, including glutamatergic synaptic transmission; positive regulation of neuromuscular synaptic transmission; and regulation of membrane potential in photoreceptor cell. Located in synaptic vesicle. Is expressed in several structures, including ganglia; neurons; organism subdivision; synaptic neuropil domain; and synaptic neuropil subdomain. Used to study Parkinson's disease and neurodegenerative disease. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 25. Orthologous to several human genes including SLC17A7 (solute carrier family 17 member 7) and SLC17A8 (solute carrier family 17 member 8). [provided by Alliance of Genome Resources, Dec 2024]

Vesicular glutamate transporter modulates sex differences in dopamine neuron vulnerability to age-related neurodegeneration.

PICALM rescues glutamatergic neurotransmission, behavioural function and survival in a Drosophila model of Abeta42 toxicity.

Study established that the majority of Drosophila octopamine (OA) neurons are also glutamatergic and identify the individual contributions of each neurotransmitter on sex-specific behaviors. Males deficient for dVGLUT solely in OA-glutamate neurons also exhibit a reduction in aggression, but without a concurrent increase in inter-male courtship. Study revealed previously undetermined role for dVGLUT in OA neurons.
Title: Octopamine neuron dependent aggression requires dVGLUT from dual-transmitting neurons.
This study demonstrated that Astrocytic glutamate transport regulates a Drosophila CNS synapse that lacks astrocyte ensheathment.

Overexpression of Drosophila GLUT is sufficient to generate excitotoxic neuropathological phenotypes; therefore, reducing VGLUT levels after nervous system injury or stress may mitigate further damage.
Title: Increased vesicular glutamate transporter expression causes excitotoxic neurodegeneration.
In the larval CNS,synaptic DVGLUT in all brain lobe neuropil compartments except for the mushroom body. Likewise in the adult CNS, glutamatergic synapses are abundant throughout all major brain structures except the mushroom body.

DVGLUT contains 10 hydrophobic regions that completely span the membrane (TMs 1-10) & that the amino & carboxyl termini are cytosolic. between TMs 4 & 5 is an unforeseen cytosolic loop of some 50 residues.
