LOCKR: A New Way to Control Cellular Function Synthetically
July 2019  |  Science News
Research team has created a totally synthetic system to act like a switch that can change gene expression, protein interactions, and the biological functions in a cell. The synthetic protein 'switch' is called LOCKR (Latching, Orthogonal Cage/Key pRotein) and has the ability to control cells with designer proteins ushers in a new era of biology.
