H. To the left Western blots against NPC1 and actin-β (ACTB) in synaptosomal extracts from wt and NPC1nmf164 mice used as input for the immunoprecipitation assays shown in the right. Immunoprecipitates were pulled down with an anti-ubiquitin antibody and without it for negative control and analysed by western blot against NPC1. MG132 was used as proteasome inhibitor. Graphs show mean ± SEM levels of NPC1 normalized to ACTB in the inputs (left) (n=3, one-way ANOVA, *pWT+MG-132=0.0496, pNPC1nmf1+MG-132=0.0358) and of NPC1 associated to ubiquitin (right) (n=3 mice, 3 month-old, one-way ANOVA, *pNPC1nmf164= 0.0237, pNPC1nmf164+MG-132= 0.0386.
