Stretching the rules: monocentric chromosomes with multiple centromere domains. [PDF]
PLoS Genetics, 2012 The centromere is a functional chromosome domain that is essential for faithful chromosome segregation during cell division and that can be reliably identified by the presence of the centromere-specific histone H3 variant CenH3.

The inner centromere is a biomolecular condensate scaffolded by the chromosomal passenger complex [PDF]
Nature Cell Biology, 2019 The inner centromere is a region on every mitotic chromosome that enables specific biochemical reactions that underlie properties, such as the maintenance of cohesion, the regulation of kinetochores and the assembly of specialized chromatin, that can ...

EWSR1 maintains centromere identity
Cell Reports, 2023 Summary: The centromere is essential for ensuring high-fidelity transmission of chromosomes. CENP-A, the centromeric histone H3 variant, is thought to be the epigenetic mark of centromere identity.

Current Biology, 2016 Centromeres, chromosomal regions that become physically linked to the spindle during cell division, ensure equal division of genetic material between daughter cells. They are ubiquitous and essential in eukaryotic life. In this primer, we ask the questions 'What defines a functional centromere?' and 'What do all centromeres have in common?' To address ...

A role for the CAL1-partner Modulo in centromere integrity and accurate chromosome segregation in Drosophila. [PDF]
PLoS ONE, 2012 The relationship between the nucleolus and the centromere, although documented, remains one of the most elusive aspects of centromere assembly and maintenance.

Gross Chromosomal Rearrangement at Centromeres
Biomolecules, 2023 Centromeres play essential roles in the faithful segregation of chromosomes. CENP-A, the centromere-specific histone H3 variant, and heterochromatin characterized by di- or tri-methylation of histone H3 9th lysine (H3K9) are the hallmarks of centromere ...

A Taz1- and Microtubule-Dependent Regulatory Relationship between Telomere and Centromere Positions in Bouquet Formation Secures Proper Meiotic Divisions. [PDF]
PLoS Genetics, 2016 During meiotic prophase, telomeres cluster, forming the bouquet chromosome arrangement, and facilitate homologous chromosome pairing. In fission yeast, bouquet formation requires switching of telomere and centromere positions.

PLoS Biology, 2020 In most plants, centromeric DNA contains highly repetitive sequences, including tandem repeats and retrotransposons; however, the roles of these sequences in the structure and function of the centromere are unclear.

Centromere size scales with genome size across Eukaryotes
Scientific Reports, 2021 Previous studies on grass species suggested that the total centromere size (sum of all centromere sizes in a cell) may be determined by the genome size, possibly because stable scaling is important for proper cell division. However, it is unclear whether

Centromere Repositioning [PDF]
Genome Research, 1999 Primate pericentromeric regions recently have been shown to exhibit extraordinary evolutionary plasticity. In this paper we report an additional peculiar feature of these regions that we discovered while analyzing, by FISH, the evolutionary conservation of primate phylogenetic chromosome IX.
