GAT-1 Antibody

SLC6A1 (Solute Carrier family 6(Neurotransmitter transporter, Gaba), Member 1), also called GABATR, GABATHG and GAT-1, encodes a gamma-aminobutyric acid (GABA) transporter, which removes GABA from the synaptic cleft. Zomot et al.(2007) showed that introduction of a negatively charged amino acid at or near one of the two putative sodium binding sites of GAT-1 from rat brain renders both net flux and exchange of GABA largely chloride independent. By in vitro functional expression studies, the GAT-1 insertion promoter (two copies of the sequence) had significantly greater promoter activity than the noninsertion (one copy of the sequence) promoter, which in turn had greater activity than a promoterless control. Studies of postmortem hippocampus from 69 African American individuals showed that overall expression decreased with age.
