Silence of the centromeres – not

Trends in Biotechnology, 2004
Centromeres are a conundrum; although many proteins associated with centomeres are conserved from yeast to humans, the underlying DNA sequence is not. A proposed solution to this problem is that an epigenetic, largely heterochromatic, state be imposed by these proteins.

Sister chromatid exchange in the centromere and centromeric area

Human Genetics, 1983
Central and peripheral sister chromatid exchanges (SCE) were evaluated separately in human phytohemagglutinin (PHA)-stimulated lymphocytes after culture for 72 h in 5-bromodeoxyuridine (BrdU) containing medium. At the same time, the length of chromosome No.

Centromere Protein A Goes Far Beyond the Centromere in Cancers

Molecular Cancer Research, 2022
Abstract Centromere dysfunctions leading to numerical chromosome alterations are believed to be closely related to human cancers. As a centromere-specific protein, centromere protein A (CENP-A) replaces the histone H3 in centromeres and is therefore considered a key factor of centromere identity ...

Plant centromeres

Current Opinion in Plant Biology, 2017
Plant centromeres, which are determined epigenetically by centromeric histone 3 (CENH3) have revealed surprising structural diversity, ranging from the canonical monocentric seen in vertebrates, to polycentric, and holocentric. Normally stable, centromeres can change position over evolutionary times or upon genomic stress, such as when chromosomes are ...

Indirect immunofluorescence of inactive centromeres as indicator of centromeric function

Human Genetics, 1986
Two previous single case reports from the literature showed the presence or absence of centromeric antigens at the site of the inactive centromeres in one (X;X) and in one (9;11) dicentric chromosome. We studied nine different dicentric chromosomes using anticentromeric antibodies and immunofluorescence techniques.

Plant Centromeres

2008
Plant centromeres are generally composed of tandem arrays of simple repeats that are typical of a particular species, but that evolve rapidly. Centromere specific retroelements are also present. These arrays associate with a centromere specific variant of histone H3 that anchors the site of the kinetochore.

Yeast centromeres

Yeast, 1987
Significant progress has been made toward understanding the roles played by conserved centromere DNA sequences in both mitotic and meiotic chromosome segregation. We are just beginning to formulate a picture of what a yeast kinetochore actually looks like and what components other than CEN DNA are necessary for function.

Tajanstvene centromere

2000
Proučavanje nukleotidnih sekvenci i struktura višeg reda molekule DNA centromernog područja predmet su istraživanja kojemu je cilj objašnjenje nastanka, funkcioniranja i nasljeđivanja centromere.

Centromere dynamics

Current Opinion in Genetics & Development, 2007
At the foundation of all eukaryotic kinetochores is a unique histone variant, known as CenH3 (centromere histone H3). We are starting to identify the histone chaperones responsible for CenH3 deposition at centromere DNA, and the mechanisms that restrict CenH3 from chromosome arms.

A cereal centromeric sequence

Chromosoma, 1996
We report the identification of a family of sequences located by in situ hybridisation to the centromeres of all the Triticeae chromosomes studied, including the supernumerary and midget chromosomes, the centromeres of all maize chromosomes and the heterochromatic regions of rice chromosomes.
