BAG3_Pro209 mutants also aggregate in muscle (C2C12) and motoneuron-like cells (NSC-34). We transiently transfected GFP-tagged BAG3 wild type or mutant constructs in C2C12 and NSC-34 cells. We then verified protein aggregation by separating the soluble fraction (western blot) and insoluble fraction (filter retardation assay (FRA)) (a,c) or verified protein aggregation by immunofluorescence (b,d). The FRA analysis is displayed for the NP-40 insoluble fraction. Relative optical densities are reported in the graphs as means ± SD of normalized values. One-Way ANOVA with Bonferroni’s multiple comparisons test were used for statistical analysis (n = 3). Scale bar = 10 µm.
