Analysis of the Localization of MEN Components by Live Cell Imaging Microscopy.

Abstract

Mitotic exit is determined by multiple spatial and temporal cues from the spindle poles and the two compartments in a dividing yeast cell-the mother and the bud. These signals are ultimately integrated by the activation of the mitotic exit network (MEN) to promote persistent release of Cdc14 from the nucleolus. Live imaging analysis using fluorescent protein tags is invaluable to dissect this critical decision-making trigger. Here, we present protocols for routine yeast live cell microscopy applicable to this problem.
