Phenotypic effects of DGAT1 (mdy) depletion on mitophagy in vivo.Figure 7a. Phenotypic assessment of DGAT1/mdy knockdown by d**ifferent RNAi transgenes by GAL4 drivers ubiquitously or in a tissue-specific manner. b. Schematic for the matrix-QC mitophagy reporter system. mCherry-GFP is targeted to the mitochondrial matrix via the specific COXVIII targeting sequence. As for mito-QC, the cytosolic mitochondrial network appears in yellow, due to red-green fluorescence. Upon mitophagy, mitochondria delivered to endolysosomes are distinguished by mCherry-only puncta, whereas GFP does not fluoresce in the acidic microenvironment. c. Representative photomicrographs of larval neuronal cell bodies expressing the matrix-QC reporter and RNAi for mdy or control driven with nSyb-GAL4. GFP is shown in green, mCherry is shown in magenta. Mitolysosomes (mCherry-only puncta) are shown in greyscale. Scale bar = 5 μm. d. Quantitative analysis of mitophagy (mitolysosome per neuronal cell body).

Figure 5Cell extracts from RPE cells stably expressing EGFP or EGFP-FAM110A arrested in mitosis by nocodazole were incubated with GFP Trap. Bound proteins were analyzed by mass spectrometry. Shown are top ten proteins that that were significantly enriched in EGFP-FAM110A complex compared to EGFP in three independent experiments. Proteins TUBB8 and TUB1AC were also significantly enriched in complex with EGFP-FAM110A. Number indicates the fold change interaction compared to the control. Cell extracts from asynchronously growing or mitotic RPE-EGFP or RPE-EGFP-FAM110A cells were incubated with GFP Trap and bound proteins were analyzed by immunoblotting. Antibody against pS10H3 was used as a marker of mitosis. Cell extracts from asynchronously growing or mitotic RPE-EGFP-FAM110A cells were incubated with CSNK1D antibody or control IgG immobilized on protein A/G beads. Bound proteins were probed with antibody against GFP or CK1δ. Staining for pS10-H3 was used as marker of the mitotic population. Scheme of the EGFP-FAM110A constructs used in the study. Numbering is based on human FAM110A. N, C, and Pro represent N-terminal, C-terminal and Pro rich domains, respectively. Cells were transfected with indicated constructs and after 48 h they were lysed in RIPA buffer. Cell extracts were immunoprecipitated with GFP Trap and probed by immunoblotting (n=2). Cells were transfected with EGFP, EGFP-FAM110A-WT or EGFP-FAM110A-FA. Cell extracts were immunoprecipitated with GFP Trap and binding of CK1 was determined by immunoblotting (n=3).

Hsp70 interacts with V‐set domain of Siglec‐5 and Siglec‐14A comparison of the relative binding affinities between Siglec‐5 WT versus R119A Fc, and Siglec‐14 WT versus R119A Fc to Hsp70 by ELISA.Figure 4A comparison of the relative binding affinities between Siglec‐5 WT versus R119A Fc, and Siglec‐14 WT versus R119A Fc to Hsp70 by ELISA. The arginine‐mutated Siglecs display lower affinity for Hsp70 in comparison with their wild‐type sequence. A lysine‐to‐alanine mutation in residue 134 in Siglec‐14 Fc (K134A) also abrogates its affinity for Hsp70, as determined by ELISA. Lysine 134 was identified as a possible residue that changes binding affinity by aligning the sequences of Siglec‐5 and Siglec‐14 with Siglec‐7. The Siglec‐14 R119A and K134A double mutant (DM) Fc reduces the interaction with Hsp70 to background levels. Antibodies against Siglec‐5 and Siglec‐14 neutralized the interaction between Siglec‐14 Fc to Hsp70, as determined by ELISA. Co‐incubation of B6N peptide with Siglec‐5 and Siglec‐14 Fc decreased binding of each Siglec to Hsp70 in an ELISA.

Single-molecule dynamics of the active mutant, hDIA1(R1204X), in XTC cells.Figure 5GFP-tagged DIA1(WT), DIA1(R1204X), and DIA1(M1190D) were transfected into XTC cells. XTC cells were spread on the PLL-coated coverslips and time-lapse images were acquired every 300 ms, illuminating the restricted areas near the cell edges, by using a single-molecule speckle microscope. Representative images are shown for DIA1(WT) (A, Movie EV5), DIA1(R1204X) (B, Movie EV6), and DIA1(M1190D) (C, Movie EV7). Circles indicate speckles showing directional movement over a distance of several micrometers. Trajectories of these speckles are also illustrated, and crosses were plotted at the end of the directional movement. Speckles showing directional movement were frequently observed in cells expressing GFP-DIA1(R1204X) (B), whereas such speckles were scarce in cells expressing GFP-DIA1(WT) (A). However, the density of these speckles in GFP-DIA1(R1204X)-expressing cells appeared lower than that in GFP-DIA1(M1190D)-expressing cells, which is considered a fully active mutant (C). To evaluate the frequency of speckles indicating directional movement, we performed a quantitative analysis (D). The number of speckles showing directional movement during 3 continuous planes was counted and were normalized by the fluorescent intensity of each cell, which corresponds to the expression level of the GFP-tagged protein. *P= 0.0288 and **P= 0.0002 Bonferroni's post hoc test following one-way ANOVA (WT; n = 5, R1204X; n = 6, M1190D; n = 6). Time is in seconds. Scale bars: 5 µm.

a) Cell cycle analysis.f4(a) Cell cycle analysis. After lentivirus gene transfer, Jurkat T cells overexpressing ATG5 or GFP were followed for the indicated times and analysed for DNA content by flow cytometry. Untransduced cells were left untreated or treated with etoposide for comparison. Values are means±s.d. (n=3). Right: representative flow cytometry diagrams for the 48 h time point. (b) Cell cycle analysis. Jurkat cells were cultured as indicated for 48 h. Only under conditions of ATG5 induction, we observed an accumulation of cells in G2- or M-phase arrest. Results are representative of three independent experiments. (c) Immunoblotting. Jurkat T cells overexpressing ATG5 or GFP were cultured for the indicated times after transduction and analysed. As controls, cells were treated with etoposide or rapamycin. Although rapamycin, similar to etoposide, induced autophagy, no increase in ATG5 expression and no cell cycle arrest were observed. ATG5 overexpression and etoposide treatment resulted in a similar expression pattern for all proteins investigated. Each immunoblot is representative of at least three independent experiments.
