Summary: Enables gamma-aminobutyric acid:proton antiporter activity and glycine:proton antiporter activity. Involved in gamma-aminobutyric acid import and glycine transport. Located in several cellular components, including cone cell pedicle; dendrite terminus; and inhibitory synapse. Is expressed in several structures, including cardiovascular system; central nervous system; eye; metanephros; and skeleton. Used to study temporal lobe epilepsy.

Study investigated VIAAT expression during development in: 4 different wildtype-strains, 1 transgenic mouse line with congenital deafness and 1 mouse line with cochlear ablation. Results identify an activity-regulated gradient of VIAAT in the superior olivary complex of NRMI mice. Its absence in other mouse strains adds a novel layer of strain-specific features in the auditory system.

GABAergic SVs that lacked the vesicular GABA transporter (VGAT) did not show the pH overshoot and acidified further to approximately 6.0. Comparison of luminal pH dynamics in the presence or absence of VGAT showed that VGAT operates as a GABA/H(+) exchanger, which is continuously required to offset GABA leakage

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.
