Meiotic pairing through barcode-like satellite DNA repeats [PDF]

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 ...

Models for the architecture of the human inner kinetochore on centromeric α-satellite CENP-A nucleosome arrays [PDF]

Nature Communications
Human kinetochores assemble onto centromeric DNA comprising repetitive arrays of the 171 bp α-satellite sequence. To understand the higher-order architecture of the inner kinetochore assembled onto α-satellite arrays, we show cryo-EM structures of CCAN ...

Defective transcription of AAGAG satellite DNA causes sex-ratio meiotic drive in Drosophila [PDF]

Nature Communications
Male germ cells have complex transcriptomes, with a large fraction of the genome being transcribed. This includes protein-coding genes (often not translated), non-coding DNA, and repetitive DNA, such as transposons and satellite DNA, which are normally ...

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 ...

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 ...

Satellitome of the Red Palm Weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae), the Most Diverse Among Insects

Frontiers in Ecology and Evolution, 2022
The red palm weevil, Rhynchophorus ferrugineus, is the most harmful species among those pests affecting palm trees. Its impact causes important economic losses around the World. Nevertheless, the genetic information of Rh.

Satellitome Analysis and Transposable Elements Comparison in Geographically Distant Populations of Spodoptera frugiperda

Life, 2022
Spodoptera frugiperda (fall armyworm) is a member of the superfamily Noctuoidea that accounts for more than a third of all Lepidoptera and includes a considerable number of agricultural and forest pest species.

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.

GlaI digestion of mouse γ-satellite DNA: study of primary structure and ACGT sites methylation

BMC Genomics, 2009
Background Patterns of mouse DNA hydrolysis with restriction enzymes are coincided with calculated diagrams of genomic DNA digestion in silico, except presence of additional bright bands, which correspond to monomer and dimer of γ-satellite DNA.
