Gating and permeation of kainate receptors: differences unveiled

Perrais, David, Veran, Julien, Mulle, Christophe·2010·Trends in Pharmacological Sciences

Abstract

Kainate receptors (KARs) represent, together with α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) and N-methyl D-aspartate (NMDA) receptors, one of the three families of ionotropic glutamate receptors. Recent advances in the study of their biophysical properties have revealed a surprising diversity. KAR-mediated excitatory postsynaptic currents (EPSCs) are often much slower than AMPA receptor-mediated EPSCs, and this is probably due to the slow deactivation rate of KARs containing the GluK4 or GluK5 subunits. By contrast, GluK3-containing receptors, unlike other AMPA/kainate receptors, desensitize faster at low agonist concentrations, making these receptors insensitive to glutamate spillover from neighboring synapses. Moreover, KARs have a wide range of sensitivities to intracellular polyamines and consequently of voltage dependent activation. Finally, newly discovered associated proteins, such as Neto1 and 2, have marked effects on receptor properties, increasing further the potential diversity of KAR functional properties. Altogether, this functional diversity of KARs could have profound consequences on their ability to shape synaptic transmission under physiological and pathological conditions.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Even within receptor families, specific subunits and combinations of them or splice variants can have diametrically opposing functional properties from others that are nominally similar.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
