| Annotation description: | Figure 3: DHHC2 (ZDHHC2) antibody was validated by siRNA DHHC2-knockdown and westernblots. DHHC2 and PSD95 (DLG4) were enriched in PSD biochemical fractions. Confocal imaging showed DHHC2 localized to dendritic puncta and the cell body. Figure 6: TIRFM imaging revealed that more DHHC2 was recruited near the membrane upon Kyn or TTX treatment (Fig. 6, B and C; and Video 4), where PSD-95 localized (Fig. S4 A). This translocation was activity sensitive as it was reversible upon washing out of Kyn (Fig. 6 D). Furthermore, we found that Kyn or TTX steadily induced colocalization of endogenous DHHC2 with PSD-95 over 48 h (Fig. 6, E and F). Figure 7: Activity-sensitive PSD-95 palmitoylation by DHHC2 is necessary for homeostatic increase of AMPARs. |
