Mitochondrial protein import: from proteomics to functional mechanisms

Schmidt, Oliver, Pfanner, Nikolaus, Meisinger, Chris·2010·Nature Reviews Molecular Cell Biology

Abstract

Mitochondria contain approximately 1,000 different proteins, most of which are imported from the cytosol. Two import pathways that direct proteins into the mitochondrial inner membrane and matrix have been known for many years. The identification of numerous new transport components in recent proteomic studies has led to novel mechanistic insight into these pathways and the discovery of new import pathways into the outer membrane and intermembrane space. Protein translocases do not function as independent units but are integrated into dynamic networks and are connected to machineries that function in bioenergetics, mitochondrial morphology and coupling to the endoplasmic reticulum.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • MOMP eventually leads to the dissipation of the mitochondrial transmembrane potential (Δψm)-mostly as a consequence of the respiratory impairment imposed by the loss of CYCS-and hence to the cessation of Δψm-dependent mitochondrial functions (including ATP synthesis and some forms of protein import).

    “Of note, MOMP eventually leads to the dissipation of the mitochondrial transmembrane potential (Δψm)—mostly as a consequence of the respiratory impairment imposed by the loss of CYCS—and hence to the cessation of Δψm-dependent mitochondrial functions (including ATP synthesis and some forms of protein import) [200–203].”

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.
