Light Used to Activate Select Proteins Inside Living Cells
http://www.medgadget.com/wp-content/uploads/2017/03/cell-man.jpg
At the*University of Alberta in Canada, researchers have devised a way of activating proteins inside a living cell using a beam of light. This will allow scientists to study how the activation of certain proteins affects the functionality of a cell.
The tech**logical breakthrough consists of attaching a photocleavable protein, one that can be broken into two pieces when light shines on it, between a target protein and that protein’s inhibitor.
While the three components remain together, the target protein can**t function, but when light is directed at the cell, the photocleavable protein comes apart releasing the inhibitor and freeing the target protein.
The video below shows the photocleavable proteins in action:
