Fig.1 A-G
- shRNA KD of Reggie1 or reggie2 results in less spines --> regulation of dendritic spine organization
- Reggie1 KO mouse no effect on spine number, but less spine synapses --> regulation of synapse organization

Fig.1 G-J
- Reggie1 and Reggie2 localize to synaptic component transport vesicles in dendrites.

Fig.2 A,B
- RFP-Reggie1 is co-transported with PSD-95 in dendrites

Fig.2 C-Fig
- Reggie1 KD causes reduction in number of spine synapses (measured as juxtaposed presynaptic FM4-64FX and postsynaptic PSD-95-EGFP staining).

Fig.3
- Reggie1 KO cells show impaired transport of PSD-95, and reduced number of synapses (measured as juxtaposed synaptophysin/PSD-95 staining)
