Annotated paper:Bencsik N, et al. "Dendritic spine morphology and memory formation depend on postsynaptic Caskin proteins" Sci Rep. 2019 Nov 14;9(1):16843 PMID:31727973
Figure(s):Figure 5, 7
Annotation description:Figure 5: "Overexpressed Caskin1 was detected predominantly within the somatodendritic region of the transfected neurons, with local enrichment within the dendritic spine heads (Fig. 5F,G). Ultrastructural analyses in Caskin1-V5 and EGFP cotransfected neurons were processed by anti-V5 pre-embedding immunocytochemistry and visualized by DAB precipitates. Our results proved that overexpressed Caskin1 was indeed present in postsynaptic dendritic spines forming synapses (see Fig. 5E)."

Figure 7: in immunofluorescence imaging of Caskin-1 and -2 double-knockout mice, overexpressed EGFP-Caskin1 co-localized with endogenous Shank2 at dendritic spines.
