All APOBEC3 family proteins differentially inhibit LINE-1 retrotransposition
Approximately 17% of the human genome is comprised of long interspersed nuclear element 1 (LINE-1, L1) non-LTR retrotransposons. L1 retrotransposition is known to be the cause of several genetic diseases, such as hemophilia A, Duchene muscular dystrophy, and so on. The L1 retroelements are also able to cause colon cancer, suggesting that L1 transposition could occur not only in germ cells, but ...
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 کاملAPOBEC3 proteins: major players in intracellular defence against LINE-1-mediated retrotransposition.
Mammalian genomes are littered with enormous numbers of transposable elements interspersed within and between single-copy endogenous genes. The only presently spreading class of human transposable elements comprises non-LTR (long terminal repeat) retrotransposons, which cover approx. 34% of the human genome. Non-LTR retrotransposons include the widespread autonomous LINEs (long interspersed nuc...

BACKGROUND Intact LINE-1 elements are the only retrotransposons encoded by the human genome known to be capable of autonomous replication. Numerous cases of genetic disease have been traced to gene disruptions caused by LINE-1 retrotransposition events in germ-line cells. In addition, genomic instability resulting from LINE-1 retrotransposition in somatic cells has been proposed as a contributi...
متن کاملTruncated ORF1 proteins can suppress LINE-1 retrotransposition in trans
Long interspersed element 1 (L1) is an autonomous non-LTR retroelement that is active in mammalian genomes. Although retrotranspositionally incompetent and functional L1 loci are present in the same genomes, it remains unknown whether non-functional L1s have any trans effect on mobilization of active elements. Using bioinformatic analysis, we identified over a thousand of human L1 loci containi...
