GATMD: γ-Aminobutyric Acid Transporter Mutagenesis Database
Since the cloning of the first γ-aminobutyric acid (GABA) transporter (GAT1; SLC6A1) from rat brain in 1990, more than 50 published studies have provided structure-function information on investigator-designed rat and mouse GAT1 mutants. To date, more than 200 of 599 GAT1 residues have been subjected to mutagenesis experiments by substitution with different amino acids, and the resulting transp...
متن کاملγ-Aminobutyric acid transporter-mediated current from bipolar cells in tiger salamander retinal slices
About 10% of bipolar cells in salamander retina synthesize and take up gamma-aminobutyric acid (GABA), and may use GABA as a neurotransmitter. As GABA uptake is electrogenic, bipolar cells expressing GABA transporters (GATs) should give transport current (IGAT) to extracellular GABA. Using whole-cell patch recording, 28 bipolar cells responded to 30-200 microM GABA puffed to the axon terminals ...
متن کاملA Binding Mode Hypothesis of Tiagabine Confirms Liothyronine Effect on γ-Aminobutyric Acid Transporter 1 (GAT1)
Elevating GABA levels in the synaptic cleft by inhibiting its reuptake carrier GAT1 is an established approach for the treatment of CNS disorders like epilepsy. With the increasing availability of crystal structures of transmembrane transporters, structure-based approaches to elucidate the molecular basis of ligand-transporter interaction also become feasible. Experimental data guided docking o...
متن کاملSpinally mediated analgesic interaction between γ-aminobutyric acid B receptor agonist and glutamate receptor antagonists in rats
Background. Many mechanisms are involved in pain transmission in the spinal cord. Therefore, combination of drugs acting on different kinds of mechanisms might be useful for analgesia. We investigated the interaction betweenγ-aminobutyric acid (GABA)B receptor agonist, baclofen, and N-methyl-D-aspartate (NMDA) receptor antagonist, AP-5, orα-amino-3-hydroxy-5-methylisoxazole-4-propionic acid ...
متن کاملSubstrate Selectivity of the Acid-activated Glutamate/γ-Aminobutyric acid (GABA) Antiporter GadC from Escherichia coli*
GadC, a central component of the Escherichia coli acid resistance system, is a Glu/GABA antiporter. A previous structural study and biochemical characterization showed that GadC exhibits a stringent pH dependence for substrate transport, with no detectable activity at pH values above 6.5. However, the substrate selectivity and the mechanism of pH-dependent transport activity of GadC remain enig...
