    ZIP3- ZnT1 physical interaction in DCN cartwheel cells. A . Proximity ligation assay (PLA) performed on DCN slices using probes for GluN2A and either ZnT1, ZIP3, or ZIP1. Analysis of PLA puncta (red) was done on the molecular layer (outlined in white) to assess protein–protein interactions in postsynaptic cells of the parallel fibers. The graph (right panel) quantifies PLA puncta normalized to ZnT1-GluN2A puncta. Statistical analysis Dunnett’s multiple comparisons test, p-value: 0.0014, F (2, 11) = 11. B . Co-immunoprecipitation assay using DCN and hippocampal lysates. Protein samples were immunoprecipitated with antibodies against GluN2A, followed by SDS-PAGE separation and immunoblotting with antibodies against ZIP3 to confirm physical interactions. Note that expected MW for ZIP3 is 37 kDa, identified MW likely represents its dimerization and glycosylation; full blots shown in Supplementary Information. C . Schematic representation of Zn 2+ transporters in DCN, indicating the ZIP3-ZnT1-GluN2A complex on the cartwheel cells of the DCN

    ZIP1- ZnT1 physical interaction in the hippocampus. A . Co-immunoprecipitation assay using SH-SY5Y cells that were immunoprecipitated with ZnT1 and then exposed to ZIP1 (left panel) or ZIP3 (right panel) antibodies.
