    RNA virus attenuation by codon pair deoptimisation is an artefact of increases in CpG/UpA dinucleotide frequencies

    Fiona Tulloch et al.
    Attenuating candidate live virus vaccines by incorporating unfavoured codon pairs to reduce translation efficiency is actually mediated though changes in frequencies of CpG and UpA dinucleotides, which make viruses more visible to the innate immune system.

    KDM2B links the Polycomb Repressive Complex 1 (PRC1) to recognition of CpG islands

    Anca M Farcas et al.
    A protein that can recognize regions of DNA with a high proportion of unmethylated CpG dinucleotides, and then recruit polycomb group proteins to these CpG islands, has been identified.

    Synthetic CpG islands reveal DNA sequence determinants of chromatin structure

    Elisabeth Wachter et al.
    Genomic landmarks, known generically as ‘CpG islands’, program chromatin structure via their richness in the dinucleotide CG and their skewed composition of DNA bases.

    Elevation of CpG frequencies in influenza A genome attenuates pathogenicity but enhances host response to infection

    Eleanor Gaunt et al.
    Mutants of influenza A virus with increased CpG dinucleotide frequencies show restricted replication and reduced or absent pathogenicity, and powerful host innate and adaptive responses to infection that confer immunity to re-infection.

    CpG and UpA dinucleotides in both coding and non-coding regions of echovirus 7 inhibit replication initiation post-entry

    Jelke Jan Fros et al.
    RNA virus replication is attenuated by an intrinsic restriction mechanism after introducing CpG/UpA dinucleotides into both non-translated and coding regions of viral genomes, which may be exploited in the design of attenuated virus vaccines.

    A KRAS-directed transcriptional silencing pathway that mediates the CpG island methylator phenotype

    Ryan W Serra et al.
    A pathway directed by the KRAS oncoprotein leads to aberrant hypermethylation and transcriptional silencing of many genes including tumor suppressors, thereby promoting tumor development.

    Action of CMG with strand-specific DNA blocks supports an internal unwinding mode for the eukaryotic replicative helicase

    Lance Langston, Mike O’Donnell
    The CMG complex, the replicative helicase in eukaryotes, uses a different mechanism from bacterial and viral helicases by engaging both strands of parental DNA with substantial force and unwinding the duplex within the central channel of CMG.

    High-throughput engineering of a mammalian genome reveals building principles of methylation states at CG rich regions

    Arnaud R Krebs et al.
    Large numbers of DNA sequence variants comprehensively define how transcription factor binding sites and CG density preserve mammalian promoters from repression by DNA methylation.

    Mcm10 promotes rapid isomerization of CMG-DNA for replisome bypass of lagging strand DNA blocks

    Lance D Langston et al.
    Biochemical data demonstrate an unexpected and critical function for the enigmatic Mcm10 protein in helping the eukaryotic CMG helicase/replisome bypass roadblocks on the DNA that may also explain Mcm10 function at origins of replication.
