Stoichiometry of the human glycine receptor revealed by direct subunit counting.

چکیده
The subunit stoichiometry of heteromeric glycine-gated channels determines fundamental properties of these key inhibitory neurotransmitter receptors; however, the ratio of α1- to β-subunits per receptor remains controversial. We used single-molecule imaging and stepwise photobleaching in Xenopus oocytes to directly determine the subunit stoichiometry of a glycine receptor to be 3α1:2β. This approach allowed us to determine the receptor stoichiometry in mixed populations consisting of both heteromeric and homomeric channels, additionally revealing the quantitative proportions for the two populations.

Automating single subunit counting of membrane proteins in mammalian cells.
Elucidating subunit stoichiometry of neurotransmitter receptors is preferably carried out in a mammalian expression system where the rules of native protein assembly are strictly obeyed. Although successful in Xenopus oocytes, single subunit counting, manually counting photobleaching steps of GFP-tagged subunits, has been hindered in mammalian cells by high background fluorescence, poor control...
متن کاملO7: Functional Characterization of Human GABAA Autoantibodies in the Context of Limbic Encephalitis
Limbic encephalitis is an adaptive autoimmune disease, induced by different autoantibodies, which target extracellular neuronal epitopes, such as NMDA or GABAB receptors1,2. Recently our group found another human antibody, which binds to the α1 subunit of the GABAA receptor. Since the GABAA receptor is responsible for the majority of fast inhibitory neurotransmission, we investigated chan...
متن کاملMolecular Insight into the Mutual Interactions of Two Transmembrane Domains of Human Glycine Receptor (TM23-GlyR), with the Lipid Bilayers
Appearing as a computational microscope, MD simulation can ‘zoom in’ to atomic resolution to assess detailed interactions of a membrane protein with its surrounding lipids, which play important roles in the stability and function of such proteins. This study has employed the molecular dynamics (MD) simulations, to determine the effect of added DMPC or DMTAP molecules on the structure of D...
متن کاملEffects of Combination of Intravenous Anesthetic Agents on Human Glycine Receptor evaluated by Artificial Neural Networks
Introduction: Intravenous general anesthetic agents are among the most important and widely used anesthetic drugs in the clinical practice. Many pharmacological studies have shown that potentiation of GABA and glycine on their receptors is the most plausible mechanism. Nevertheless, there is limited information on the effects of co-administration of two or more of these agents. However, expe...
متن کاملAtomic Force Microscopy Reveals the Stoichiometry and Subunit Arrangement of the 4 3 GABAA Receptor
The GABAA receptor is a chloride-selective ligand-gated ion channel of the Cys-loop superfamily. The receptor consists of five subunits arranged pseudosymmetrically around a central pore. The predominant form of the receptor in the brain contains 1-, 2-, and 2-subunits in the arrangement , counter-clockwise around the pore. GABAA receptors containing instead of -subunits, although a minor compo...
