  • Characterization of a Domoic Acid Binding Site from Pacific Razor Clam
    Aquatic Toxicology 69 (2004) 125–132 Characterization of a domoic acid binding site from Pacific razor clam Vera L. Trainer∗, Brian D. Bill NOAA Fisheries, Northwest Fisheries Science Center, Marine Biotoxin Program, 2725 Montlake Blvd. E., Seattle, WA 98112, USA Received 5 November 2003; received in revised form 27 April 2004; accepted 27 April 2004 Abstract The Pacific razor clam, Siliqua patula, is known to retain domoic acid, a water-soluble glutamate receptor agonist produced by diatoms of the genus Pseudo-nitzschia. The mechanism by which razor clams tolerate high levels of the toxin, domoic acid, in their tissues while still retaining normal nerve function is unknown. In our study, a domoic acid binding site was solubilized from razor clam siphon using a combination of Triton X-100 and digitonin. In a Scatchard analysis using [3H]kainic acid, the partially-purified membrane showed two distinct receptor sites, a high affinity, low capacity site with a KD (mean ± S.E.) of 28 ± 9.4 nM and a maximal binding capacity of 12 ± 3.8 pmol/mg protein and a low affinity, high capacity site with a mM affinity for radiolabeled kainic acid, the latter site which was lost upon solubilization. Competition experiments showed that the rank order potency for competitive ligands in displacing [3H]kainate binding from the membrane-bound receptors was quisqualate > ibotenate > iodowillardiine = AMPA = fluorowillardiine > domoate > kainate > l-glutamate. At high micromolar concentrations, NBQX, NMDA and ATPA showed little or no ability to displace [3H]kainate. In contrast, Scatchard analysis 3 using [ H]glutamate showed linearity, indicating the presence of a single binding site with a KD and Bmax of 500 ± 50 nM and 14 ± 0.8 pmol/mg protein, respectively.

  • Comparative Thermodynamics of Partial Agonist Binding to An
    COMPARATIVE THERMODYNAMICS OF PARTIAL AGONIST BINDING TO AN AMPA RECEPTOR BINDING DOMAIN A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Madeline Martínez May 2015 © 2015 Madeline Martínez ALL RIGHTS RESERVED Comparative Thermodynamics of Partial Agonist Binding to an AMPA Receptor Binding Domain Madeline Martínez, Ph.D. Cornell University 2015 AMPA receptors, ligand-gated cation channels endogenously activated by glutamate, mediate the majority of rapid excitatory synaptic transmission in the vertebrate central nervous system and are crucial for information processing within neural networks. Their involvement in a variety of neuropathologies and injured states makes them important therapeutic targets, and understanding the forces that drive the interactions between the ligands and protein binding sites is a key element in the development and optimization of potential drug candidates. Calorimetric studies yield quantitative data on the thermodynamic forces that drive binding reactions. This information can help elucidate mechanisms of binding and characterize ligand- induced conformational changes, as well as reduce the potential unwanted effects in drug candidates. The studies presented here characterize the thermodynamics of binding of a series of 5’substituted willardiine analogues, partial agonists to the GluA2 LBD under several conditions. The moiety substitutions (F, Cl, I, H, and NO2) explore a range of electronegativity, pKa, radii, and h-bonding capability. Competitive binding of these ligands to glutamate-bound GluA2 LBD at different pH conditions demonstrates the effects of charge in the enthalpic and entropic components of the Gibb’s free energy of binding.

In each case, the properties of the expressed receptors were examined using two-electrode current and voltage clamp techniques and compared by examining their pharmacology using dose-response curve analysis (D/R) and constructing current-voltage (l-V) relationships using non-NMDA agonists. Fully-grown immature oocytes (stages V and VI) removed from female Xenopus laevis were microinjected with exogenous messenger ribonucleic acid (mRNA) and after a period of incubation (2-3 days), became responsive to a variety of agonists including central nervous system (CNS) transmitters.

  • Functional Impact of Interacting Protein on Kainate Receptors: Necab1 and Neto Proteins
    Instituto de Neurociencias de Alicante Universidad Miguel Hernandez Thesis manuscript for: PhD in Neuroscience Functional impact of interacting protein on kainate receptors: NeCaB1 and NeTo proteins. Jon Palacios Filardo Supervised by: Prof. Juan Lerma Alicante, 2014 Agradecimientos/Acknowledgments Agradecimientos/Acknowledgments Ahora que me encuentro escribiendo los agradecimientos, me doy cuenta que esta es posiblemente la única sección de la tesis que no será corregida. De manera que los escribiré tal como soy, tal vez un poco caótico. En primer lugar debo agradecer al profesor Juan Lerma, por la oportunidad que me brindó al permitirme realizar la tesis en su laboratorio. Más que un jefe ha sido un mentor en todos estos años, 6 exactamente, en los que a menudo al verme decía: “Jonny cogió su fusil”, y al final me entero que es el título de una película de cine… Pero aparte de un montón de anécdotas graciosas, lo que guardaré en la memoria es la figura de un mentor, que de ciencia todo lo sabía y le encantaba compartirlo. Sin duda uno no puede escribir un libro así (la tesis) sin un montón de gente alrededor que te enseña y ayuda. Como ya he dicho han sido 6 años conviviendo con unos maravillosos compañeros, desde julio de 2008 hasta presumiblemente 31 de junio de 2014. De cada uno de ellos he aprendido mucho; técnicamente toda la electrofisiología se la debo a Ana, con una paciencia infinita o casi infinita. La biología molecular me la enseñó Isa. La proteómica la aprendí del trío Esther-Ricado-Izabella. Joana y Ricardo me solventaron mis primeras dudas en el mundo de los kainatos.

Although overactivation of glutamate receptors also contributes to axonal injury, the mechanisms are poorly understood. Our goal was to ϩ elucidate the mechanisms of kainate receptor–dependent axonal Ca2 deregulation. ϩ Methods: Dorsal column axons were loaded with a Ca2 indicator and imaged in vitro using confocal laser-scanning micros- copy. ϩ Results: Activation of glutamate receptor 6 (GluR6) kainate receptors promoted a substantial increase in axonal [Ca2 ].

  • Inhibitory Effects of Glutamate-Stimulated Astrocytes on Action Potentials Evoked by Bradykinin in Cultured Dorsal Root Ganglion Neurons
    Tokai J Exp Clin Med., Vol. 39, No. 1, pp. 14-24, 2014 Inhibitory Effects of Glutamate-stimulated Astrocytes on Action Potentials Evoked by Bradykinin in Cultured Dorsal Root Ganglion Neurons Kazuo SUZUKI, Minehisa ONO and Kenji TONAKA Department of Biomedical Engineering, Tokai University (Received September 26, 2013; Accepted January 20, 2014) Patch-clamp and Ca2+-imaging techniques have revealed that astrocytes have dynamic properties including ion channel activity and release of neurotransmitters, such as adenosine triphosphate (ATP) and glutamate. Here, we used the patch-clamp technique to determine whether ATP and glutamate is able to modulate the bradykinin (BK) response in neurons cultured with astrocytes in the mouse dorsal root ganglia (DRG) in order to clarify the role of astrocytes in nociceptive signal transmission. Astrocytes were identified using a fluorescent anti-GFAP antibody. The membrane potential of astrocytes was about -39 mV. The application of glutamic acid (GA) to the bath evoked the opening of two types of Cl- channel in the astrocyte cell membrane with a unit conductance of about 380 pS and 35 pS in the cell-attached mode, respectively. ATP application evoked the opening of two types of astrocyte K+ channel with a unit conductance of about 60 pS and 29 pS, respectively. Application of BK to the neuron evoked an action potential (spike). Concomitant BK application with ATP increased the frequency of BK-evoked neuron spikes when neurons coexisted with astrocytes. Stimulation of BK with GA inhibited the BK-evoked spike under similar conditions. The application of furosemide, a potent cotransporter (Na+-K+-2Cl-) inhibitor, prior to stimulation of BK with GA blocked inhibition of the spike.

On the basis of rational ligand design, a new class of selective antagonists, represented by (2S,4R)-4-(2- carboxyphenoxy)pyrrolidine-2-carboxylic acid (1b), for cloned homomeric kainic acid receptors subtype 1 (GluK1) was attained μ ± μ (Ki =4 M). In a functional assay, 1b displayed full antagonist activity with IC50 =6 2 M. A crystal structure was obtained of 1b when bound in the ligand binding domain of GluK1. A domain opening of 13−14° was seen compared to the structure with glutamate, consistent with 1b being an antagonist. A structure−activity relationship study showed that the chemical nature of the tethering atom (C, O, or S) linking the pyrrolidine ring and the phenyl ring plays a key role in the receptor selectivity profile and that substituents on the phenyl ring are well accommodated by the GluK1 receptor.
