Histones serve to both package and organize DNA within the nucleus. In addition to histone
post-translational modification and chromatin remodelling complexes, histone variants …

Kinetochores are large protein assemblies that connect chromosomes to microtubules of the
mitotic and meiotic spindles in order to distribute the replicated genome from a mother cell to …

The centromere is the region of the chromosome that directs its segregation in mitosis and
meiosis. Although the functional importance of the centromere has been appreciated for …

Kinetochores assemble onto specialized centromeric CENP-A (centromere protein A)
nucleosomes (CENP-ANuc) to mediate attachments between chromosomes and the mitotic …

When fully extended, one copy of the three billion base pair human genome reaches a
length of over two meters. Yet, it must be packaged into the nucleus of a cell with an average …

The compaction of genomic DNA into chromatin has profound implications for the regulation
of key processes such as transcription, replication and DNA repair. Nucleosomes, the …

Since discovery of the centromere-specific histone H3 variant CENP-A, centromeres have
come to be defined as chromatin structures that establish the assembly site for the complex …

A critical requirement for mitosis is the distribution of genetic material to the two daughter
cells. The central player in this process is the macromolecular kinetochore structure, which …

The exact positions of nucleosomes along genomic DNA can influence many aspects of
chromosome function. However, existing methods for mapping nucleosomes do not provide …

The Polycomb group of epigenetic enzymes represses expression of developmentally
regulated genes in many eukaryotes. This group includes the Polycomb repressive complex …
