Conservation of Major Satellite DNAs in Snake Heterochromatin

Animals, 2023
Repetitive DNA sequences constitute a sizeable portion of animal genomes, and tandemly organized satellite DNAs are a major part of them. They are usually located in constitutive heterochromatin clusters in or near the centromeres or telomeres, and less ...

Evaluation of intra- and interspecific divergence of satellite DNA sequences by nucleotide frequency calculation and pairwise sequence comparison

Biological Procedures Online, 2003
Satellite DNA sequences are known to be highly variable and to have been subjected to concerted evolution that homogenizes member sequences within species.

Stretching the Rules: Monocentric Chromosomes with Multiple Centromere Domains [PDF]

, 2012
The centromere is a functional chromosome domain that is essential for faithful chromosome segregation during cell division and that can be reliably identified by the presence of the centromere-specific histone H3 variant CenH3.

Characterization of Two Satellite DNA Families in the Genome of the Oomycete Plant Pathogen Phytophthora parasitica

Frontiers in Genetics, 2020
Satellite DNA is a class of repetitive sequences that are organized in long arrays of tandemly repeated units in most eukaryotes. Long considered as selfish DNA, satellite sequences are now proposed to contribute to genome integrity.

Transcription of satellite DNAs in insects [PDF]

, 2011
Chromatin condensation is an important regulatory mechanism of gene silencing as well as gene activation for the hundreds of functional protein genes harbored in heterochromatic regions of different insect species.

DNA Methylation Patterns of a Satellite Non-coding Sequence – FA-SAT in Cancer Cells: Its Expression Cannot Be Explained Solely by DNA Methylation

Frontiers in Genetics, 2019
Satellite ncRNAs are emerging as key players in cell and cancer pathways. Cancer-linked satellite DNA hypomethylation seems to be responsible for the overexpression of satellite non-coding DNAs in several tumors.

Satellite DNA as a target for TaqMan real-time PCR detection of the pinewood nematode, Bursaphelenchus xylophilus [PDF]

, 2007
The pinewood nematode (PWN), Bursaphelenchus xylophilus , is a major pathogen of conifers, which impacts on forest health, natural ecosystem stability and international trade. As a consequence, it has been listed as a quarantine organism in Europe.

Influence of DNA methylation on positioning and DNA flexibility of nucleosomes with pericentric satellite DNA [PDF]

Open Biology, 2015
DNA methylation occurs on CpG sites and is important to form pericentric heterochromatin domains. The satellite 2 sequence, containing seven CpG sites, is located in the pericentric region of human chromosome 1 and is highly methylated in normal cells ...

Satellite DNA libraries and centromere evolution [PDF]

, 2008
Related species share a pool of satellite DNA sequences known as a satellite DNA library. Such sequences may persist in the genome for long evolutionary time at latent locations and can be amplified in any species.
