Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos
Constitutive heterochromatin is essential for transcriptional silencing and genome integrity. The establishment of constitutive heterochromatin in early embryos and its role in early fruitfly development are unknown. Lysine 9 trimethylation of histone H3 ( ...
Springernature2024Chromosome organization shapes replisome dynamics in Caulobacter crescentus
Suliana Manley, Chen Zhang, Laurent Casini
DNA replication in bacteria takes place on highly compacted chromosomes, where segregation, transcription, and repair must occur simultaneously. Within this dynamic environment, colocalization of sister replisomes has been observed in many bacterial specie ...
Nature Portfolio2024CENP-A and CENP-B collaborate to create an open centromeric chromatin state
Beat Fierz, Wei Cai, Harsh Nagpal
Centromeres are epigenetically defined via the presence of the histone H3 variant CENP-A. Contacting CENP-A nucleosomes, the constitutive centromere associated network (CCAN) and the kinetochore assemble, connecting the centromere to spindle microtubules d ...
Berlin2023Centromere structure and function: lessons from Drosophila
The fruit fly Drosophila melanogaster serves as a powerful model organism for advancing our understanding of biological processes, not just by studying its similarities with other organisms including ourselves but also by investigating its differences to u ...
Bethesda2023A satellite DNA array barcodes chromosome 7 and regulates totipotency via ZFP819
Didier Trono, Gabriela Ecco, Helen Mary Rowe
Mammalian genomes are a battleground for genetic conflict between repetitive elements and KRAB-zinc finger proteins (KZFPs). We asked whether KZFPs can regulate cell fate by using ZFP819, which targets a satellite DNA array, ZP3AR. ZP3AR coats megabase reg ...
2022TFIIH moonlighting at telomeres
Although telomeres are essential for chromosome stability, they represent fragile structures in our genome. Telomere shortening occurs during aging in cells lacking telomerase due to the end replication problem. In addition, recent work uncovered that the ...
COLD SPRING HARBOR LAB PRESS, PUBLICATIONS DEPT2022TRIM37 prevents formation of centriolar protein assemblies by regulating Centrobin
Pierre Gönczy, Coralie Busso, Benita Wolf, Fernando Romero Balestra, Tessa Vivianne Averink, Alizée Buff
TRIM37 is an E3 ubiquitin ligase mutated in Mulibrey nanism, a disease with impaired organ growth and increased tumor formation. TRIM37 depletion from tissue culture cells results in supernumerary foci bearing the centriolar protein Centrin. Here, we chara ...
ELIFE SCIENCES PUBLICATIONS LTD2021Centromeres are dismantled by foundational meiotic proteins Spo11 and Rec8
Meiotic processes are potentially dangerous to genome stability and could be disastrous if activated in proliferative cells. Here we show that two key meiosis-defining proteins, the topoisomerase Spo11 (which forms double-strand breaks) and the meiotic coh ...
NATURE RESEARCH2021Self-organization of parS centromeres by the ParB CTP hydrolase
Paolo De Los Rios, Stefano Zamuner
ParABS systems facilitate chromosome segregation and plasmid partitioning in bacteria and archaea. ParB protein binds centromeric parS DNA sequences and spreads to flanking DNA. We show that ParB is an enzyme that hydrolyzes cytidine triphosphate (CTP) to ...
2019Functional analysis of the telomeric long non-coding RNA TERRA
Telomeres are nucleoprotein structures present in the end of linear chromosomes. In humans, a core complex of 6 proteins cap and protect the chromosome ends from being recognized as double-strand breaks and eliciting unwanted DNA damage and repair response ...
