    APOBEC3A deaminates transiently exposed single-strand DNA during LINE-1 retrotransposition

    Sandra R Richardson et al.
    Combining in vitro and in vivo assays demonstrates that the cytidine deaminase APOBEC3A can inhibit LINE-1 retrotransposition by deaminating transiently exposed single-strand DNA that arises during the process of LINE-1 integration.

    Human LINE-1 retrotransposition requires a metastable coiled coil and a positively charged N-terminus in L1ORF1p

    Elena Khazina, Oliver Weichenrieder
    Human LINE-1 retrotransposition is found to critically depend on the rapidly evolving N-terminal sequence of the LINE-1 ORF1 protein and on the metastability of its coiled coil domain, indicating uncharacterized steps in LINE-1 retrotransposition.

    LINE-1 protein localization and functional dynamics during the cell cycle

    Paolo Mita et al.
    A combination of functional, biochemical and imaging studies show that LINE-1/L1 proteins and mRNA enter the nucleus through mitotic nuclear membrane breakdown, interact with components of the DNA replication fork and mediate retrotransposition during S phase.

    Activation of individual L1 retrotransposon instances is restricted to cell-type dependent permissive loci

    Claude Philippe et al.
    The expression of human L1 retrotransposons is highly locus-specific and variable between different cell types.

    Retrotransposons: On the move

    Sandra L Martin
    The mechanisms by which a retrotransposon called LINE-1 duplicates itself and spreads through the human genome are becoming clearer.

    Retrocopying expands the functional repertoire of APOBEC3 antiviral proteins in primates

    Lei Yang et al.
    Genomes take advantage of the gene-duplicating ability of retroelements to birth novel innate immune defense genes.

    Non-invasive detection of urothelial cancer through the analysis of driver gene mutations and aneuploidy

    Simeon U Springer et al.
    The creation of a non-invasive assay for detecting urothelial cancer could have a profound impact on how we find and treat the disease.

    Functional divergence of paralogous transcription factors supported the evolution of biomineralization in echinoderms

    Jian Ming Khor, Charles A Ettensohn
    A gene duplication event has permitted the functional specialization of a homeodomain transcription factor through changes in exon-intron organization and these changes have supported the evolution of a major, phylum-level morphological novelty.

    An ancient germ cell-specific RNA-binding protein protects the germline from cryptic splice site poisoning

    Ingrid Ehrmann et al.
    Cell division by meiosis during sperm production depends on expression of an RNA-binding protein that prevents abnormal RNA-processing pathways.

    Expansion of the fatty acyl reductase gene family shaped pheromone communication in Hymenoptera

    Michal Tupec et al.
    A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.
