HSP70 chaperones RNA-free TDP-43 into anisotropic intranuclear liquid spherical shells
Open accessAbstract
The makings of anisosomes: Phase separation of proteins within the cell can produce a liquid-inside-a-liquid phase resembling oil droplets in water. Yu et al. now report that an RNA-binding protein called TDP-43, in which mutation and aggregation are linked to amyotrophic lateral sclerosis and frontotemporal dementia, phase separates into complex droplets, which they named anisosomes. This process occurred when TDP-43 lost its ability to bind RNA through disease-causing mutation or posttranslational acetylation. Anisosomes have spherical shells of TDP-43 (with properties of a liquid crystal) surrounding centers of the protein chaperone HSP70. Chaperone activity was required to maintain liquidity. Anisosomes formed in neurons in vivo when proteasome activity was inhibited and were converted into aggregates when adenosine triphosphate (ATP) levels fell. Science , this issue p. eabb4309

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.
