Abstract excerpt
The (Na+ + Cl-)-coupled gamma-aminobutyric acid (GABA) transporter GAT-1 keeps synaptic levels of this neurotransmitter low and thereby enables efficient GABA-ergic transmission. Extracellular loops (III, IV, and V) have been shown to contain determinants for GABA selectivity and affinity. Here w...
