The informant: a jumping gene

Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have developed a new method for studying gene regulation, by employing a jumping gene as an informant. Published online today in Nature Genetics, the new method is called GROMIT. It enables researchers to systematically explore the very large part of our genome that does not code for proteins, and which likely plays a large role in making each of us unique, by controlling when, where and to what extent genes are turned on, or expressed. Thanks to GROMIT, scientists can also create mouse models for human diseases such as Down syndrome.
