Regulation of transposable elements by DNA modifications [PDF]
Nature Reviews Genetics, 2019 Maintenance of genome stability requires control over the expression of transposable elements (TEs), whose activity can have substantial deleterious effects on the host. Chemical modification of DNA is a commonly used strategy to achieve this, and it has long been argued that the emergence of 5-methylcytosine (5mC) in many species was driven by the ...

Cross-Regulation between Transposable Elements and Host DNA Replication [PDF]
Viruses, 2017 Transposable elements subvert host cellular functions to ensure their survival. Their interaction with the host DNA replication machinery indicates that selective pressures lead them to develop ancestral and convergent evolutionary adaptations aimed at conserved features of this fundamental process.

PERSPECTIVE: TRANSPOSABLE ELEMENTS, PARASITIC DNA, AND GENOME EVOLUTION
Evolution, 2001The nature of the role played by mobile elements in host genome evolution is reassessed considering numerous recent developments in many areas of biology. It is argued that easy popular appellations such as "selfish DNA" and "junk DNA" may be either inaccurate or misleading and that a more enlightened view of the transposable element-host relationship ...

DNA sequence of the maize transposable element Dissociation
Nature, 1984The DNA sequence of the terminal 4.2 kilobases (kb) of the 30-kb insertion in the endosperm sucrose synthase gene of maize mutant sh-m5933 shows that it comprises two identical 2,040-base pair (bp) segments, one inserted in the reverse direction into the other. We suggest that the 2,040-bp sequence is an example of the transposable element Dissociation

IS1294, a DNA Element That Transposes by RC Transposition
Plasmid, 2000IS1294, found on the ColD-like resistance plasmid pUB2380, is IS91-like. It is an active 1.7-kb insertion sequence that lacks terminal inverted repeats, displays insertion-site specificity, and does not generate direct repeats of the target site. The element has one large open reading frame, tnp(1294), encoding a transposase of 351 amino acids, related

Transposable elements and DNA transposition in eukaryotes
Current Opinion in Cell Biology, 1990An interesting and surprising outcome of the last 15 years of Investigation into the organization of DNA sequences in eukaryotic genomes is the realization that a substantial proportion of each genome is made up of transposable DNA sequences. These sequences occur in families of repeated elements that may make up l&15% of the genome.

DNA sequence of the transposable element IS1
Molecular and General Genetics MGG, 1979The nucleotide sequence of an IS1 element recently transposed into the lacI gene is reported. This sequence is nearly identical to one previously reported for another IS1 element (Ohtsubo and Ohtsubo, 1978). The implications of this similarity are discussed.

DNA methylation dynamics at transposable elements in mammals
Essays in Biochemistry, 2019Abstract Transposable elements dominate the mammalian genome, but their contribution to genetic and epigenetic regulation has been largely overlooked. This was in part due to technical limitations, which made the study of repetitive sequences at single copy resolution difficult. The advancement of next-generation sequencing assays in the

Potential movement of transposable elements through DNA circularization
Current Genetics, 2016The generation of circular DNAs is a relatively unrecognized type of genomic structural variation, but recent findings point to a possible role of circular DNAs in the movement of transposable elements. Circularization of genomic DNA is observed across eukaryotic species, in a range of different cell types, and from all parts of the genome.
