RB dependent transcriptional regulation at mitotic centromeres preserves genome stability [PDF]
Life Science AllianceLoss of the RB tumor suppressor drives centromere transcription, resulting in DNA damage and whole chromosome segregation errors. Transcripts derived from centromere repeats play a critical role in the localization and activity of kinetochore components ...

Kinetochore mutations and histone phosphorylation pattern changes accompany holo- and macro-monocentromere evolution [PDF]
Nature CommunicationsCentromeres are essential for kinetochore assembly and spindle attachment. While chromosomes of most species are monocentric with a single centromere, a minority exhibit holocentricity, with a centromere along the chromatid length.

Only the Rye Derived Part of the 1BL/1RS Hybrid Centromere Incorporates CENH3 of Wheat
Frontiers in Plant Science, 2021 The precise assembly of the kinetochore complex at the centromere is epigenetically determined by substituting histone H3 with the centromere-specific histone H3 variant CENH3 in centromeric nucleosomes.

The cotton centromere contains a Ty3-gypsy-like LTR retroelement. [PDF]
PLoS ONE, 2012 The centromere is a repeat-rich structure essential for chromosome segregation; with the long-term aim of understanding centromere structure and function, we set out to identify cotton centromere sequences. To isolate centromere-associated sequences from

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 ...

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.

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.

Variation in the CENP-A sequence association landscape across diverse inbred mouse strains
Cell Reports, 2023 Summary: Centromeres are crucial for chromosome segregation, but their underlying sequences evolve rapidly, imposing strong selection for compensatory changes in centromere-associated kinetochore proteins to assure the stability of genome transmission ...

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.
