Impact of non-LTR retrotransposons in the differentiation and evolution of anatomically modern humans. [PDF]
Mob DNA, 2018 ABSTRACT Transposable Elements are biologically important components of eukaryote genomes. In particular, non-LTR retrotransposons (N-LTRrs) extensively shaped the human genome throughout evolution. In this study, we compared retrotransposon insertions differentially present in the genomes of Anatomically Modern Humans, Neanderthals ...

Horizontal Transfer of Non-LTR Retrotransposons from Arthropods to Flowering Plants. [PDF]
Mol Biol Evol, 2018 Even though lateral movements of transposons across families and even phyla within multicellular eukaryotic kingdoms have been found, little is known about transposon transfer between the kingdoms Animalia and Plantae. We discovered a novel non-LTR retrotransposon, AdLINE3, in a wild peanut species.

The Wide Distribution and Change of Target Specificity of R2 Non-LTR Retrotransposons in Animals. [PDF]
PLoS One, 2016 Transposons, or transposable elements, are the major components of genomes in most eukaryotes. Some groups of transposons have developed target specificity that limits the integration sites to a specific nonessential sequence or a genomic region to avoid gene disruption caused by insertion into an essential gene.

Identification of rDNA-Specific Non-LTR Retrotransposons in Cnidaria [PDF]
Molecular Biology and Evolution, 2006 Ribosomal RNA genes are abundant repetitive sequences in most eukaryotes. Ribosomal DNA (rDNA) contains many insertions derived from mobile elements including non-long terminal repeat (non-LTR) retrotransposons. R2 is the well-characterized 28S rDNA-specific non-LTR retrotransposon family that is distributed over at least 4 bilaterian phyla.

LTR retrotransposons in fungi. [PDF]
, 2011 Transposable elements with long terminal direct repeats (LTR TEs) are one of the best studied groups of mobile elements. They are ubiquitous elements present in almost all eukaryotic genomes.

Mobile DNA, 2010 Non-long terminal repeat (non-LTR) retrotransposons are present in most eukaryotic genomes. In some species, such as humans, these elements are the most abundant genome sequence and continue to replicate to this day, creating a source of endogenous ...

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

Transposable Elements and Genome Size Variations in Plants [PDF]
Genomics & Informatics, 2014 Although the number of protein-coding genes is not highly variable between plant taxa, the DNA content in their genomes is highly variable, by as much as 2,056-fold from a 1C amount of 0.0648 pg to 132.5 pg.

Frontiers in Genetics, 2013 The molecular mechanisms of the transposition of non-long terminal repeat (non-LTR) retrotransposons are not well understood; the key questions of how the 3’-ends of cDNA copies integrate and how site-specific integration occurs remain unresolved ...

The Esterase and PHD Domains in CR1-Like Non-LTR Retrotransposons [PDF]
Molecular Biology and Evolution, 2003 Most active non-LTR (long terminal repeat) retrotransposons carry two open reading frames (ORFs) encoding ORF1p and ORF2p proteins. The ORF2p proteins are relatively well studied and are known to contain endonuclease/reverse transcriptase domains. At the same time, the biological function of ORF1p proteins remains poorly understood, except in that they
