Mitochondrial matrix Ca 2 + as an intrinsic signal regulating mitochondrial motility in axons
Open accessAbstract
The proper distribution of mitochondria is particularly vital for neurons because of their polarized structure and high energy demand. Mitochondria in axons constantly move in response to physiological needs, but signals that regulate mitochondrial movement are not well understood. Aside from producing ATP, Ca 2+ buffering is another main function of mitochondria. Activities of many enzymes in mitochondria are also Ca 2+ -dependent, suggesting that intramitochondrial Ca 2+ concentration is important for mitochondrial functions. Here, we report that mitochondrial motility in axons is actively regulated by mitochondrial matrix Ca 2+ . Ca 2+ entry through the mitochondrial Ca 2+ uniporter modulates mitochondrial transport, and mitochondrial Ca 2+ content correlates inversely with the speed of mitochondrial movement. Furthermore, the miro1 protein plays a role in Ca 2+ uptake into the mitochondria, which subsequently affects mitochondrial movement.

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.
