Global regulator of mRNA editing found
Date:2/6/2014

ntified more than 400 new mRNA editing sites the majority regulated by a single protein called ADR-1, which does not directly edit mRNA but rather regulated how editing occurred by binding to the messenger RNAs subject to editing.

"Cells process their genetic code in a way analogous to how the programming language Java compiles modern software. Both systems use an intermediate representation that is modified depending on its environment" said co-first author Boyko Kakaradov, a bioinformatics PhD student in the Yeo lab. "We're now finding how and why the mRNA code is being changed en route to the place of execution."

The scientists noted that a protein similar to ADR-1 is expressed by humans, and that many of the same mRNA targets exist in people too. "So it is likely that a similar mechanism exists to regulate editing in humans," said Hundley, adding that she and colleagues will now turn to teasing out the specifics of how proteins like ADR-1 regulate editing and how they might be exploited "to modulate editing for the treatment of human diseases."
