Abstract

Mitochondria are complex organelles whose dysfunction underlies a broad spectrum of human diseases. Identifying all of the proteins resident in this organelle and understanding how they integrate into pathways represent major challenges in cell biology. Toward this goal, we performed mass spectrometry, GFP tagging, and machine learning to create a mitochondrial compendium of 1098 genes and their protein expression across 14 mouse tissues. We link poorly characterized proteins in this inventory to known mitochondrial pathways by virtue of shared evolutionary history. Using this approach, we predict 19 proteins to be important for the function of complex I (CI) of the electron transport chain. We validate a subset of these predictions using RNAi, including C8orf38, which we further show harbors an inherited mutation in a lethal, infantile CI deficiency. Our results have important implications for understanding CI function and pathogenesis and, more generally, illustrate how our compendium can serve as a foundation for systematic investigations of mitochondria.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In pulsed SILAC data at 24h post LPS and mock stimulation, the M/L ratios decreased for ~80% of annotated mitochondrial proteins in LPS vs MOCK samples, and for nearly all mitochondrial proteins with a higher mitochondrial localization prediction score (over 95% of the 156 proteins with a score >20 of the 472 measured mitochondrial proteins).

    “we saw a decrease in the M/L ratios (a proxy for increased degradation) of ~80% of annotated mitochondrial proteins in LPS vs. MOCK samples (Fig. 4D)”
  • MitoCarta consists of 1098 identified proteins.

    “The most recent mammalian mitochondrial compendium (MitoCarta) consists of 1098 identified proteins [209].”

  • The number of oxidatively-modified mitochondrial proteins characterized may represent a small fraction of the estimated 1100-1400 total mitochondrial proteins.

    “The number of oxidatively-modified mitochondrial proteins we characterized may represent a small fraction of the estimated number of 1100–1400 total mitochondrial proteins [40], [41].”
  • A recent compendium of mitochondrial proteins from 14 different mouse tissues indicates that white adipocyte mitochondria contain a more diverse protein repertoire than mitochondria from heart, skeletal muscle, or brain.

    “Interestingly, a recent compendium of mitochondrial proteins from 14 different mouse tissues indicates that white adipocyte mitochondria contain a more diverse protein repertoire than mitochondria from heart, skeletal muscle, or brain (31).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
