GABA transporter 1 (GAT-1) also known as sodium- and chloride-dependent GABA transporter 1 is a protein that in humans is encoded by the SLC6A1 gene.[1][2]



GAT-1 a gamma-aminobutyric acid (GABA) transporter, which removes GABA from the synaptic cleft.[3]


SLC6A1 has been shown to interact with STX1A.[4][5][6]
