| Annotation description: | Kainate receptor subunit Glur7 (=GRIK3) 22/11/2017 Pim Fig.1: "GluR7-Containing Presynaptic KARs Facilitate MF Short-Term Synaptic Plasticity" PPF is significantly reduced in GluR7-/- mice. PPF is a presynaptic phenomenon. Fig.2: "Long-Term Potentiation (LTP) Is Impaired in GluR7-/- Mice" Fig.3: "Subcellular localization and association of GluR6 and GluR7 subunits" Fig.4: "Properties of recombinant and native GluR7-containing KARs" - Based on integration of in vivo, PPI and heterologous expression data, the authors conclude that presynaptic modulation of SV release is mediated by GluR6/Glur7 heteromers. - The GluR6 KO animal has been demonstrated to display both pre and postsynaptic defects which overlaps with the conclusion of the primary paper of this ticket. |
