By tracking the flow of information in a cell preparing to split, Johns Hopkins scientists have identified a protein mechanism that coordinates and regulates the dynamics of shape change necessary for division of a single cell into two daughter cells. The protein, called 14-3-3, sits at an intersection where it integrates converging signals from within the cell and cues cell shape change and, ultimately, the splitting that allows for normal and abnormal cell growth, such as in tumors. In a report published Nov...
