CG-dinucleotide suppression enables antiviral defense targeting non-self RNA

Vertebrate genomes exhibit marked CG-suppression, that is lower than expected numbers of 5’-CG-3’ dinucleotides1. This feature is likely due to C-to-T mutations that have accumulated over hundreds of millions of years, driven by CG-specific DNA methyl transferases and spontaneous methyl-cytosine deamination. Remarkably, many RNA viruses of vertebrates that are not substrates for DNA methyl transferases mimic the CG-suppression of their hosts2-4. This striking property of viral genomes is unexpla...
