Abstract

For nearly three decades, the sequence of the human mitochondrial genome (mtDNA) has provided a molecular framework for understanding maternally inherited diseases. However, the vast majority of human mitochondrial disorders are caused by nuclear genome defects, which is not surprising since the mtDNA encodes only 13 proteins. Advances in genomics, mass spectrometry, and computation have only recently made it possible to systematically identify the complement of over 1,000 proteins that comprise the mammalian mitochondrial proteome. Here, we review recent progress in characterizing the mitochondrial proteome and highlight insights into its complexity, tissue heterogeneity, evolutionary origins, and biochemical versatility. We then discuss how this proteome is being used to discover the genetic basis of respiratory chain disorders as well as to expand our definition of mitochondrial disease. Finally, we explore future prospects and challenges for using the mitochondrial proteome as a foundation for systems analysis of the organelle.

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

  • Alternative splicing often leads to the inclusion or exclusion of mitochondrial targeting sequences, leading to two mature proteins that have identical warheads but are localized to two different places.

    “Alternative splicing often leads to the inclusion or exclusion of mitochondrial targeting sequences, leading to two mature proteins that have identical warheads but are localized to two different places 13 .”

    From How many human proteoforms are there? (2018) · cites this paper as [13]

    The Dual Localization section says alternative splicing can produce two proteins from one gene, one with a mitochondrial targeting sequence, that localize to different compartments. It does not establish that this often happens or that the resulting mature proteins have identical functional regions (“warheads”). Page numbers are not available in our copy. (LLM, conf=0.85)

  • 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].”

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.
