Light can be used to control the transport of proteins from the cell nucleus with the aid of a light-sensitive, genetically modified plant protein. Biologists working in the field of optogenetics have now developed such a tool. The researchers employed methods from synthetic biology and combined a light sensor from the oat plant with a transport signal. This makes it possible to use external light to precisely control the location and hence the activity of proteins in mammalian cells.
