That story has been PR'd out of all proportions. We've known for half a century that DNA sequences regulate expression of genes. The novelty is only that for a small percentage of genre, regulators seem to be located not adjacent to the coding region, but within it. Then again, we knew this was true for some non-protein coding genes. In any case, the evidence for this conclusion is still very incomplete. Just because a piece of DNA can be bound by a protein, it doesn't mean there's a function to the interaction. So no huge implications here.
