    Figure 3. <t>BAG3</t> interacts with RAB GTPases in a dephosphorylation- dependent manner (A) Phosphosite mutant variants of BAG3 were transiently expressed in A7r5 cells as FLAG-epitope tagged proteins followed by anti-FLAG immunopre- cipitation and mass spectrometry. (B) HSC70 was detected in complexes of wild-type BAG3, and BAG3-T285A/ S289A and BAG3-T285D/S289D mutant variants by interaction proteomics. HSPB1 was significantly more abundant (LIMMA-moderated t test p value < 0.05) in pull-downs with the dephosphorylation-mimicking BAG3- T285A/S289A. Heatmap shows protein abundance as log2-transformed mean intensity compared to mean background intensity (FLAG-BAG3- construct/empty). See Data S1A for more information. (C) Principal-component analysis based on label-free quantification (LFQ) in- tensities of 42 proteins identified as differentially abundant (ANOVA p value < 0.05 with Tukey’s post hoc test FDR < 0.05). Empty, empty vector transfected controls (black); WT, wild-type BAG3 (green); DD, BAG3-T285D/ S289D (blue); AA, BAG3-T285A/S289A (red). See Data S1B for more infor- mation. (D) Gene Ontology (GO) terms enriched among proteins identified as BAG3 interactors. GO terms were selected from significantly enriched categories (FDR-corrected p value < 0.05). For GO-term identifier numbers, see Data S1C. (E) Volcano plot visualizing the log2 transformed ratio of mean protein abundance in pull-downs with BAG3-T285A/S289A compared to BAG3- T285D/S289D (log2 (AA/DD)), plotted against log10 (LIMMA-moderated t

    Figure 6. CMT2-causing RAB7A-L129F induces an overactivation of CASA in patient cells (A) Schematic presentation of the altered GTPase cycle of RAB7A-L129F as determined by McCray et al.61 RAB7A activity is controlled by a guanine nucleotide exchange factor (GEF) and a GTPase-activating protein (GAP). (B) Lymphoid cells of a control subject and CMT2 patient were treated with solvent () or BafA1 (+) for 7 h. Lysates were probed with specific antibodies against the indicated proteins. Multiple isoforms of SYNPO2 are detectable in this cell type. (C) Data obtained under (B) were quantified. Protein levels observed in solvent- treated control cells were set to 1 and were compared to levels in solvent- treated patient cells to determine changes in the steady-state levels. The dashed line indicates the control value. Data are shown as mean values ± SEM, n = 4 with two biological replicates performed in each independent experi- ment. (D) Data obtained under (B) were quantified. The ratio of protein levels with and without BafA1 treatment (ratio ± BafA1) was determined. The dashed line in- dicates a ratio of 1 with no changes upon BafA1 treatment. Data are shown as mean values ± SEM, n = 4 with two biological replicates performed in each independent experiment. (E) Schematic presentation of the stress-dependent regulation of BAG3. Statistical analysis was carried out using two-tailed unpaired t test with Welch’s correction: *p < 0.05; ns, non-significant.
