Sex and the TEs: transposable elements in sexual development and function in animals

open access: yesMobile DNA, 2019
Transposable elements are endogenous DNA sequences able to integrate into and multiply within genomes. They constitute a major source of genetic innovations, as they can not only rearrange genomes but also spread ready-to-use regulatory sequences able to

Author Correction: Regulation of transposable elements by DNA modifications [PDF]

open access: yesNature Reviews Genetics, 2019
The originally published article contained an error in Figure 2a: for the left side of the figure part (showing piRNA-directed DNA methylation of mouse transposable elements), DNMT3A/B should have been DNMT3C. The article has now been corrected online.

Perspective for Studying the Relationship of miRNAs with Transposable Elements

open access: yesCurrent Issues in Molecular Biology, 2023
Transposable elements are important sources of miRNA, long non-coding RNAs genes, and their targets in the composition of protein-coding genes in plants and animals.

LTR-retrotransposons in R. exoculata and other crustaceans [PDF]

open access: yes, 2013
Transposable elements are major constituents of eukaryote genomes and have a great impact on genome structure and stability. They can contribute to the genetic diversity and evolution of organisms. Knowledge of their distribution among several genomes is

The evolution of tyrosine-recombinase elements in Nematoda. [PDF]

open access: yesPLoS ONE, 2014
Transposable elements can be categorised into DNA and RNA elements based on their mechanism of transposition. Tyrosine recombinase elements (YREs) are relatively rare and poorly understood, despite sharing characteristics with both DNA and RNA elements ...

Nucleotide sequence of the transposable DNA-element IS2

open access: yesNucleic Acids Research, 1979
The complete sequence of the transposable DNA element IS2 in gal OP-308:: IS2 (I) has been determined. This element is 1.327 bp long. The integrated element is flanked by a five base pair long sequence duplication. The termini of IS2 are not perfect inverted repeats, but a close approximation.

EpiTEome: Simultaneous detection of transposable element insertion sites and their DNA methylation levels

open access: yesGenome Biology, 2017
The genome-wide investigation of DNA methylation levels has been limited to reference transposable element positions. The methylation analysis of non-reference and mobile transposable elements has only recently been performed, but required both genome ...
