Abstract

We described a cell free system involving total homogenates of metaphase CHO cells, which yields telophase-like assembly of nuclear envelopes around mitotic chromosomes. During formation of the nuclear envelope in vitro, the three major lamina polypeptides (lamins A, B, and C) assemble around chromosomes and become dephosphorylated, similar to their behavior in vivo during telophase. Nuclear lamina and envelope assembly apparently do not require free ATP and are strongly inhibited by gamma-S-ATP, supporting the notion that these processes are regulated by protein dephosphorylation. Immunological depletion of disassembled lamins from the initial assembly system results in strong inhibition of subsequent nuclear envelope assembly, directly demonstrating that the lamins are involved in this process.

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.
