What's a GeneRIF?

cortical axon terminals co-expressing VGLUT1 and VGAT can evoke simultaneously monosynaptic glutamate and gamma-aminobutyric acid responses.
Title: Co-expression of VGLUT1 and VGAT sustains glutamate and GABA co-release and is regulated by activity in cortical neurons.
Data show that VIAAT is a vesicular Cl(-) transporter that co-transports Cl(-) with GABA or glycine in a membrane-potential-dependent manner, and that Cl(-) plays an essential role in vesicular storage of GABA and glycine.
Title: Vesicular inhibitory amino acid transporter is a Cl-/gamma-aminobutyrate Co-transporter.
GABAergic synapses in cortical axon terminals express both vesicular transporters VGAT and VGLUT1.
Title: VGLUT1 and VGAT are sorted to the same population of synaptic vesicles in subsets of cortical axon terminals.
VGLUT1 is sorted diurnally to the plasma membrane to modulate glutamate transmission during a day/night cycle, whereas VGAT expression is not oscillating but is increased in the presence of a light/dark cycle.
Title: Time of day-dependent sorting of the vesicular glutamate transporter to the plasma membrane.
Concomitantly with the loss of some subpopulations of VGAT-containing neurons, there was an up-regulation of VGAT synthesis in all remaining GABA neurons as early as 1 week after pilocarpine injection.
Title: Changes in vesicular transporters for gamma-aminobutyric acid and glutamate reveal vulnerability and reorganization of hippocampal neurons following pilocarpine-induced seizures.
In mature neocortex neuronal cultures, VGLUT1 and VIAAT exhibit bidirectional and opposite regulation by prolonged activity changes.
Title: Homeostatic scaling of vesicular glutamate and GABA transporter expression in rat neocortical circuits.
functional neuronal VIAAT is present in glucagon-containing secretory granules in pancreatic alpha-cells
Title: Vesicular inhibitory amino acid transporter is present in glucagon-containing secretory granules in alphaTC6 cells, mouse clonal alpha-cells, and alpha-cells of islets of Langerhans.
Glycine is released from synaptic vesicles when VIAAT is coexpressed with the neural transporter GlyT2.
Title: The transporters GlyT2 and VIAAT cooperate to determine the vesicular glycinergic phenotype.
As a whole, the results provide original evidence that vGAT expression is altered in the 6-hydroxydopamine model of Parkinson's disease.
Title: Unilateral 6-hydroxydopamine lesion of dopamine neurons and subchronic L-DOPA administration in the adult rat alters the expression of the vesicular GABA transporter in different subsets of striatal neurons and in the substantia nigra, pars reticulata.
VIAAT is expressed in rat islets and is more abundant in the mantle

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
