Conformation of the neurotransmitter γ-aminobutyric acid in liquid water.
We study the conformation and reorientation dynamics of the inhibitory neurotransmitter γ-aminobutyric acid (GABA) under neutral and acidic conditions using a combination of broadband dielectric relaxation spectroscopy and polarization-resolved femtosecond mid-infrared pump-probe spectroscopy. We find that both zwitterionic and cationic GABA adopt nearly linear conformations in aqueous solution...
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 کاملIsoflurane regulates atypical type-A γ-aminobutyric acid receptors in alveolar type II epithelial cells.
BACKGROUND Volatile anesthetics act primarily through upregulating the activity of γ-aminobutyric acid type A (GABAA) receptors. They also exhibit antiinflammatory actions in the lung. Rodent alveolar type II (ATII) epithelial cells express GABAA receptors and the inflammatory factor cyclooxygenase-2 (COX-2). The goal of this study was to determine whether human ATII cells also express GABAA re...
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 کاملEfficient Modulation of γ-Aminobutyric Acid Type A Receptors by Piperine Derivatives
Piperine activates TRPV1 (transient receptor potential vanilloid type 1 receptor) receptors and modulates γ-aminobutyric acid type A receptors (GABAAR). We have synthesized a library of 76 piperine analogues and analyzed their effects on GABAAR by means of a two-microelectrode voltage-clamp technique. GABAAR were expressed in Xenopus laevis oocytes. Structure-activity relationships (SARs) were ...
