| Annotation description: | Fig.9: "Electron micrographs of CA1 rat hippocampal sections demonstrating immunogold labeling for GluR3 in asymmetric axospinous synapses." - Literal: "CA1 neuropil displayed asymmetric synapses immunoreactive for GluR3, which was localized throughout both the postsynaptic density (PSD) and the synaptic cleft (Fig. 9)." Note: "The specificity of MAb:3B3 for GluR3 in brain tissue sections was demonstrated by preincubating MAb:3B3 with the GluR1, GluR2, and GluR3 fusion proteins. The GluR3 fusion protein entirely blocked the immunoreactivity of MAb:3B3 in cortical sections (Fig. 2; only CA1 shown), while this immunoreactivity was not altered with the GluR1 and GluR2 fusion proteins compared to controls in which the fusion proteins were omitted." - Based on the known transmembrane topology of the protein, the "integral component of ... membrane" term was chosen. |
