(Phys.org) -- Using a new tool allowing proteins in a living cell to be manipulated in real time, researchers at Johns Hopkins have stumbled across the answer to a longstanding debate about where and how a certain protein is turned on in the cell. Reporting in the February 2012 issue of Nature Chemical Biology, scientists show that protein kinase A is also activated in the nucleus rather than inside the cells body, a challenge to traditional beliefs.
