CTCF and the emergence of metazoan diversity [Evolution]

CTCF and the emergence of metazoan diversity [Evolution]: The great majority of metazoans belong to bilaterian phyla. They diversified during a short interval in Earth’s history known as the Cambrian explosion, ∼540 million years ago. However, the genetic basis of these events is poorly understood. Here we argue that the vertebrate genome organizer CTCF (CCCTC-binding factor) played an...
