Chromatin remodeling plays a central role in the regulation of gene expression by providing the transcription machinery with dynamic access to an otherwise tightly packaged genome. Further, nucleosome movement by chromatin remodelers is essential to several important biological processes, including chromosome assembly and segregation, DNA replication and repair, embryoni… Web4.4 Chromosome segregation. Failure to maintain accurate chromosome segregation during cell division is a well-characterized aspect of biological aging (Baker et al., 2004 ), leading to cellular senescence ( Baker et al., 2008 ). This is critically dependent on the kinetochore attachment protein BubR1, which plays a role in the spindle assembly ...
