Centromere domain organization and histone modifications
Brazilian Journal of Medical and Biological Research, 2002 Centromere function requires the proper coordination of several subfunctions, such as kinetochore assembly, sister chromatid cohesion, binding of kinetochore microtubules, orientation of sister kinetochores to opposite spindle poles, and their movement ...

Epigenetic dynamics of centromeres and neocentromeres in Cryptococcus deuterogattii.
PLoS Genetics, 2021 Deletion of native centromeres in the human fungal pathogen Cryptococcus deuterogattii leads to neocentromere formation. Native centromeres span truncated transposable elements, while neocentromeres do not and instead span actively expressed genes.

Heterochromatin and RNAi regulate centromeres by protecting CENP-A from ubiquitin-mediated degradation. [PDF]
PLoS Genetics, 2018 Centromere is a specialized chromatin domain that plays a vital role in chromosome segregation. In most eukaryotes, centromere is surrounded by the epigenetically distinct heterochromatin domain. Heterochromatin has been shown to contribute to centromere

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.

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 ...

Atypical centromeres in plants – what they can tell us
Frontiers in Plant Science, 2015 The centromere, visible as the primary constriction of condensed metaphase chromosomes, is a defined chromosomal locus essential for genome stability. It mediates transient assembly of a multi-protein complex, the kinetochore, which enables interaction ...

Sequential assembly of centromeric proteins in male mouse meiosis. [PDF]
PLoS Genetics, 2009 The assembly of the mitotic centromere has been extensively studied in recent years, revealing the sequence and regulation of protein loading to this chromosome domain. However, few studies have analyzed centromere assembly during mammalian meiosis. This

Epigenetically-inherited centromere and neocentromere DNA replicates earliest in S-phase. [PDF]
PLoS Genetics, 2010 Eukaryotic centromeres are maintained at specific chromosomal sites over many generations. In the budding yeast Saccharomyces cerevisiae, centromeres are genetic elements defined by a DNA sequence that is both necessary and sufficient for function ...

Centromere plasmid: a new genetic tool for the study of Plasmodium falciparum. [PDF]
PLoS ONE, 2012 The introduction of transgenes into Plasmodium falciparum, a highly virulent human malaria parasite, has been conducted either by single crossover recombination or by using episomal plasmids.

A Positive Spin on the Centromere [PDF]
Journal of End-to-End-testing, 2009 The properties of centromeric nucleosomes have been the subject of considerable debate and controversy. Furuyama and Henikoff (2009) now provide surprising evidence that centromeric nucleosomes wrap DNA in an orientation that is opposite to that of canonical nucleosomes.
