“‘We can take the whole, intact protein, just the way nature made it, and stick this little knob on it that allows us to turn it on and off with light,’ said Hahn, Thurman Distinguished Professor of Pharmacology and a UNC Lineberger Comprehensive Cancer Center member. ‘It’s like a switch.’

The switch that Hahn, Dokholyan and colleagues developed is versatile and fast – they can toggle a protein on or off as fast as they can toggle their light. By changing the intensity of light, they can also control how much of the protein is activated or inactivated. And by controlling the timing of irradiation, they can control exactly how long proteins are activated at different points in the cell…”
