Figure(s):Figures 4-6
Annotation description:Figure 4: Confocal imaging of hippocampal neuronal cultures with co-staining for Homer1c-mCherry and β2-adaptin-GFP (AP2B1) show this protein is localized at the postsynapse.

Figure 5: time-lapse experiments on neurons co-expressing Homer1c and fluorophore-tagged AP2B1 showed high association with PSDs.

Figure 6: to dissect the spatial organization of endocytic proteins relative to the clathrin structure at
the endocytic zone (EZ), authors used two-color single-molecule localization microscopy (SMLM). Halo-CLCa co-transfected with GFP-tagged AP2B1 showed that it was often distributed in smaller patches around and sometimes within the EZ marked by CLCa.
