γ-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 کاملGATMD: 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 کاملP145: The Role of γ-Aminobutyric Acid Receptor in The Social Anxiety Disorder
Social anxiety disorder (SAD) is the one of the most common anxiety disorders. Despite its high prevalence, the disorder is still considerably undiagnosed and untreated. The disease places a massive burden on patient’s lives, affecting not only their social interactions but also their educational and professional activities, thereby constituting a severe disability. γ-aminobutyric acid (GABA) s...
متن کاملMethylenetetrahydrofolate reductase deficiency alters levels of glutamate and γ-aminobutyric acid in brain tissue.
Methylenetetrahydrofolate reductase (MTHFR) is an enzyme key regulator in folate metabolism. Deficiencies in MTHFR result in increased levels of homocysteine, which leads to reduced levels of S-adenosylmethionine (SAM). In the brain, SAM donates methyl groups to catechol-O-methyltransferase (COMT), which is involved in neurotransmitter analysis. Using the MTHFR-deficient mouse model the purpose...
متن کاملMetabolism and functions of gamma-aminobutyric acid.
Gamma-aminobutyric acid (GABA), a four-carbon non-protein amino acid, is a significant component of the free amino acid pool in most prokaryotic and eukaryotic organisms. In plants, stress initiates a signal-transduction pathway, in which increased cytosolic Ca2+ activates Ca2+/calmodulin-dependent glutamate decarboxylase activity and GABA synthesis. Elevated H+ and substrate levels can also st...
