Retrotransposons shape species-specific embryonic stem cell gene expression [PDF]
Retrovirology, 2015 Over half of our genome is composed of retrotransposons, which are mobile elements that can readily amplify their copy number by replicating through an RNA intermediate. Most of these elements are no longer mobile but still contain regulatory sequences that can serve as promoters, enhancers or repressors for cellular genes.
