ADAR1 restricts LINE-1 retrotransposition
Adenosine deaminases acting on RNA (ADARs) are involved in RNA editing that converts adenosines to inosines in double-stranded RNAs. ADAR1 was demonstrated to be functional on different viruses exerting either antiviral or proviral effects. Concerning HIV-1, several studies showed that ADAR1 favors viral replication. The aim of this study was to investigate the composition of the ADAR1 ribonucl...
متن کاملLINE-1 Retrotransposition Activity in Human Genomes
Highly active (i.e., "hot") long interspersed element-1 (LINE-1 or L1) sequences comprise the bulk of retrotransposition activity in the human genome; however, the abundance of hot L1s in the human population remains largely unexplored. Here, we used a fosmid-based, paired-end DNA sequencing strategy to identify 68 full-length L1s that are differentially present among individuals but are absent...
متن کاملAllelic heterogeneity in LINE-1 retrotransposition activity.
De novo LINE-1 (long interspersed element-1, or L1) retrotransposition events are responsible for approximately 1/1,000 disease-causing mutations in humans. Previously, L1.2 was identified as the likely progenitor of a mutagenic insertion in the factor VIII gene in a patient with hemophilia A. It subsequently was shown to be one of a small number of active L1s in the human genome. Here, we demo...
متن کاملAPOBEC3 proteins inhibit human LINE-1 retrotransposition.
The human cytidine deaminase family APOBEC3 represents a novel group of proteins in the field of innate defense mechanisms that has been shown to be active against a variety of retroviruses. Here we examined whether members of the APO-BEC3 family have an impact on retrotransposition of human long interspersed nuclear elements (LINE-1s or L1s). Using a retrotransposition reporter assay in HeLa c...
متن کاملGenomic Deletions Created upon LINE-1 Retrotransposition
LINE-1 (L1) retrotransposition continues to impact the human genome, yet little is known about how L1 integrates into DNA. Here, we developed a plasmid-based rescue system and have used it to recover 37 new L1 retrotransposition events from cultured human cells. Sequencing of the insertions revealed the usual L1 structural hallmarks; however, in four instances, retrotransposition generated larg...
