Long terminal repeat - Wikipedia
A long terminal repeat ( LTR) is a pair of identical sequences of DNA, several hundred base pairs long, which occur in eukaryotic genomes on either end of a series of genes or pseudogenes that form a retrotransposon or an endogenous retrovirus or a retroviral provirus.
LTR retrotransposon - Wikipedia
LTR retrotransposons are class I transposable elements (TEs) characterized by the presence of long terminal repeats (LTRs) directly flanking an internal coding region. As retrotransposons, they mobilize through reverse transcription of their mRNA and integration of the newly created cDNA into another genomic location.

Jul 15, 2021 · LTR retrotransposons (LTR-RTs) are ubiquitous and represent the dominant repeat element in plant genomes, playing important roles in functional variation, genome plasticity and evolution.
Long terminal repeats power evolution of genes and gene …
Sep 19, 2016 · Retrotransposons often carry long terminal repeats (LTRs) for retrovirus-like reverse transcription and integration into the genome. We report an extraordinary impact of a group of LTRs from the mammalian endogenous retrovirus-related ERVL retrotransposon class on gene expression in the germline and beyond.
Long terminal repeats: from parasitic elements to building blocks …
Jun 2, 2016 · The life-cycle of Endogenous retroviruses (ERVs), also called long terminal repeat (LTR) retrotransposons, begins with transcription by RNA Pol II followed by reverse transcription and re-integration into the host genome.
Lineage-specific amplification and epigenetic regulation of LTR ...
Jul 27, 2023 · LTR-RTs transpose by employing a ‘copy-and-paste’ mechanism via an RNA intermediate, thus contributing to their considerable copies and often playing a crucial role in genome expansion. In addition, LTR-RTs insertion and deletion maintains the balance of …
