text: Eukaryotic cells store their chromosomes in a single nucleus. This is important
to maintain genomic integrity, as chromosomes packaged into separate nuclei (micronuclei)
are prone to massive DNA damage. During mitosis, higher eukaryotes disassemble
their nucleus and release individualized chromosomes for segregation. How numerous
chromosomes subsequently reform a single nucleus has remained unclear. Using image-based
screening of human cells, we identified barrier-to-autointegration factor (BAF)
as a key factor guiding membranes to form a single nucleus. Unexpectedly, nuclear
assembly does not require BAF?s association with inner nuclear membrane proteins
but instead relies on BAF?s ability to bridge distant DNA sites. Live-cell imaging
and in vitro reconstitution showed that BAF enriches around the mitotic chromosome
ensemble to induce a densely cross-bridged chromatin layer that is mechanically
stiff and limits membranes to the surface. Our study reveals that BAF-mediated
changes in chromosome mechanics underlie nuclear assembly with broad implications
for proper genome function.
