Abstract excerpt
LINE-1 (L1) retrotransposons are replicating repetitive elements that, by mass, are the most-abundant sequences in the human genome. Over one-third of mammalian genomes are the result, directly or indirectly, of L1 retrotransposition. L1 encodes two proteins: ORF1, an RNA-binding protein, and ORF2, an endonuclease/reverse transcriptase. Both proteins are required for L1 mobilization. Apart from the obvious...
