    (A – D) Blue Native (BN)-PAGE analyses of four cell lines stably expressing MICOS-APEX2 fusion proteins in the corresponding MICOS KO cell lines along with WT HEK293 cells expressing an empty vector (EV) or IM-APEX2 fusion protein used as control cell line. Efficient incorporation of (A) <t>MIC10-,</t> (B) MIC13-, (C) MIC26- and (D) MIC27-APEX2 fusion proteins (enclosed by solid rectangles) into the MICOS complex is observed using the respective antibodies. The dotted rectangles represent loss of various MICOS proteins in the respective KO cell lines. Coomassie stain is used as loading control comprising regions between 500 and 800 kDa. (E) Transmission electron microscopy (TEM) images demonstrating the MICOS-APEX2, IM-APEX2 and matrix-APEX2 submitochondrial localization in various cell lines. DAB oxidation catalysed by APEX2 results in local deposition of DAB polymer. All the MICOS-APEX2 fusion proteins as well as the IM control reveal the DAB staining in the intermembrane space (IMS) as well as intracristal space confirming the orientation of APEX2 towards the IMS. The matrix-APEX2 reveals matrix DAB staining as expected. Scale bar 500 nm. (F) Images acquired by STED super-resolution nanoscopy demonstrate the pattern of biotinylation in individual mitochondria resulting from MICOS-APEX2 fusion proteins. Biotinylation is prevalent at the rim of mitochondria as indicated by white arrows. The IM-APEX2 reveals similar biotinylation pattern to MICOS-APEX2 different to matrix-APEX2. The MICOS complex, enriched at the CJs, is marked using an anti-MIC60 antibody. Scale bar 500 nm.

Conversely, a majority of the enriched proteins are unique interactors (55.1 %) for MIC10-, MIC13-, MIC26- and MIC27-APEX2 fusion proteins when compared to the IM-APEX2 control. (B and C) Proximity proteome representation of enriched hits shared between any three (B) or any two (C) MICOS-APEX2 groups upon using the respective APEX2 control. (D) Unique interactors of the respective MICOS-APEX2 fusion proteins upon using the respective APEX2 control are shown. The proteins were colour-coded in accordance to the functions assigned in MitoCarta3.0 and the node shapes represent the affiliation to Log 2 FC enriched or FOM category as in previous figures. The interactions are shown by lines connecting the different nodes where the gene names of the interactors are used. MICOS subunits present in yellow represent the preys, whereas MICOS subunits in orange represent the employed APEX2-fused baits.

    (A and B) Heatmap representing the MIC10-, MIC13-, MIC26- and MIC27-APEX2 interactomes obtained using matrix-APEX2 (A) and IM-APEX2 (B) as controls. The heatmaps of the corresponding interactomes are distributed into mitochondrial subcompartments and functions. Missing proteins are crossed out.

    Techniques:

    (A – D) BN-PAGE analyses reveals a consistent reduction of OXPHOS complex I and IV assembly in MIC10 and MIC60 KO cells among all MICOS KO cells (indicated by dotted rectangles). Coomassie stain is used as loading control comprising regions between 500 and 800 kDa. (E – G) Representative TEM images demonstrating the mitochondrial ultrastructure of individual MICOS KO cells (E). Quantification reveals a significant reduction in the number of crista junctions (CJs) per crista in MIC10 KO, MIC13 KO, MIC19 KO and MIC60 KO cells (F) and cristae number per unit length (µm) in MIC10 KO, MIC13 KO and MIC60 KO cells (G), (n = 36-79) (N = 2). (H and I) Representative mitochondrial stress test assessed with Seahorse XF analyzer using sequential injection of oligomycin, FCCP and rotenone/antimycin a (n = 8-9) (H). Quantification from various biological replicates shows a significant decrease in mitochondrial coupling efficiency in MIC10 KO and MIC60 KO cells (N = 4) (I). (J and K) Representative individual complex feeding run as assessed in permeabilized cells with Seahorse XF analyzer by sequential injections of rotenone, succinate, antimycin a and ascorbate/TMPD (n = 8-9) (J). Quantification of different biological replicates reveals a significant decrease of complex II and complex IV activities in MIC10 KO, MIC13 KO and MIC60 KO, whereas complex I activity is significantly decreased only in MIC10 KO and MIC60 KO cells (K) (N = 6). Data are represented as mean ± SEM (H – K). Statistical analysis was performed using one sample t -test with * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001 (I (Basal OCR) and K). Statistical analysis was performed using one-way ANOVA with * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001 (F, G, I (SRC and coupling efficiency)). N represents the number of biological replicates.
