Photocleavable Proteins at Work (VIDEO)
Caption
This video shows light-activated control of protein localization in mammalian cells. The protein is initially in the cytoplasm and excluded from the nucleus of the cell (blue area in the middle each cell). Upon illumination, the part of the protein that prevents it from entering the nucleus is cleaved off and the protein is now able to enter the nucleus. The concentration of protein is represented by the color, with blue indicating a low concentration, and red representing a high concentration.
