unc-83 encodes a novel component of the nuclear envelope and is essential for proper nuclear migration
Abstract
Nuclear migration plays an essential role in the growth and development of a wide variety of eukaryotes. Mutations in unc-84, which encodes a conserved component of the nuclear envelope, have been shown to disrupt nuclear migration in two C. elegans tissues. We show that mutations in unc-83 disrupt nuclear migration in a similar manner in migrating P cells, hyp7 precursors and the intestinal primordium, but have no obvious defects in the association of centrosomes with nuclei or the structure of the nuclear lamina of migrating nuclei. We also show that unc-83 encodes a novel transmembrane protein. We identified three unc-83 transcripts that are expressed in a tissue-specific manner. Antibodies against UNC-83 co-localized to the nuclear envelope with lamin and UNC-84. Unlike UNC-84, UNC-83 localized to only specific nuclei, many of which were migratory. UNC-83 failed to localize to the nuclear envelope in unc-84 mutants with lesions in the conserved SUN domain of UNC-84, and UNC-83 interacted with the SUN domain of UNC-84 in vitro, suggesting that these two proteins function together during nuclear migration. We favor a model in which UNC-84 directly recruits UNC-83 to the nuclear envelope where they help transfer force between the cytoskeleton and the nucleus.

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.
