Meiotic pairing through barcode-like satellite DNA repeats

Nature Communications
During meiosis, chromosomes must find, pair, and synapse with their homologous partners in the crowded milieu of the nucleus. Although homology detection generally relies on recombination, pairing can occur in its absence, suggesting alternative ...

Uncoupling of satellite DNA and centromeric function in the genus Equus. [PDF]

PLoS Genetics, 2010
In a previous study, we showed that centromere repositioning, that is the shift along the chromosome of the centromeric function without DNA sequence rearrangement, has occurred frequently during the evolution of the genus Equus.

Evolutionary Dynamics of Satellite DNA Repeats across the Tettigoniidae Family: Insights from Genomic Analysis [PDF]

Biomolecules
Satellite DNA repeats are repetitive DNA sequences found in eukaryotic genomes, typically consisting of short DNA motifs repeated in tandem arrays. Despite the vast body of literature on satellite DNA repeats in other taxa, investigations specifically ...

Antibiotics induce overexpression of alpha satellite DNA accompanied with epigenetic changes at alpha satellite arrays as well as genome-wide [PDF]

Epigenetics & Chromatin
The transcription of satellite DNA is highly sensitive to environmental factors and represents a source of genomic instability. Therefore, tight regulation of (peri)centromeric transcription is essential for genome maintenance.

Multi-tissue characterization of the constitutive heterochromatin proteome in Drosophila identifies a link between satellite DNA organization and transposon repression. [PDF]

PLoS Biology
Noncoding satellite DNA repeats are abundant at the pericentromeric heterochromatin of eukaryotic chromosomes. During interphase, sequence-specific DNA-binding proteins cluster these repeats from multiple chromosomes into nuclear foci known as ...

Topoisomerase I is an evolutionarily conserved key regulator for satellite DNA transcription [PDF]

Nature Communications
RNA Polymerase (RNAP) II transcription on non-coding repetitive satellite DNAs plays an important role in chromosome segregation, but a little is known about the regulation of satellite transcription.

Differential enrichment of H3K9me3 at annotated satellite DNA repeats in human cell lines and during fetal development in mouse

Epigenetics & Chromatin, 2021
Background Trimethylation of histone H3 on lysine 9 (H3K9me3) at satellite DNA sequences has been primarily studied at (peri)centromeric regions, where its level shows differences associated with various processes such as development and malignant ...

Painting of Fourth and the X-Linked 1.688 Satellite in D. melanogaster Is Involved in Chromosome-Wide Gene Regulation

Cells, 2020
Chromosome-specific regulatory mechanisms provide a model to understand the coordinated regulation of genes on entire chromosomes or on larger genomic regions. In fruit flies, two chromosome-wide systems have been characterized: The male-specific lethal (

Uhrf1 governs the proliferation and differentiation of muscle satellite cells

iScience, 2022
Summary: DNA methylation is an essential form of epigenetic regulation responsible for cellular identity. In muscle stem cells, termed satellite cells, DNA methylation patterns are tightly regulated during differentiation.

Locational diversity of alpha satellite DNA and intergeneric hybridization aspects in the Nomascus and Hylobates genera of small apes. [PDF]

PLoS ONE, 2014
Recently, we discovered that alpha satellite DNA has unique and genus-specific localizations on the chromosomes of small apes. This study describes the details of alpha satellite localization in the genera Nomascus and Hylobates and explores their ...
