Figure(s):Figure 6, 7
Annotation description:Figure 6b,c. Confocal imaging of cultured rat hippocampal SDC2-overexpressing neurons at DIV2 shows localization of CASK, LIN7B and surface-NR1 (GRIN1) at the tip of dendritic spines.

Figure 7. Mutating the C2 motif of SDC2 leads to disruption of the SDC2-CASK-LIN7B-NMDAR complex, and consequently the localization of CASK, LIN7B and NR2B at the postsynaptic density was significantly reduced.

Figure 8. Disruption of the SDC2-CASK and CASK-LIN7B interactions reduces NMDA-induced calcium influx and impairs SDC2-induced spine formation.
