title: Measuring proteolysis in mitosis.
abstract: The targeted destruction of key regulators helps to drive the cell cycle. Here we describe a quantitative assay to measure destruction of different regulators in mitotic cells. This assay uses GFP-tagged substrates and time-lapse fluorescence microscopy of single cells to pinpoint the timing of destruction of different substrates at different stages in mitosis.
