FIGURE 3: A scheme of biphasic Cdc42 polarization in the G1 phase. Cdc42 polarization occurs stepwise triggered by its two GEFs: first by Bud3 and subsequently by Cdc24 [37]. Whi5 partitions the G1 phase into two temporal steps, and the ‘Start' transition corresponds to the time of the nuclear exit of approximately 50% of Whi5 [24]. The sites of Cdc42 polarization prior to the onset of cytokinesis and until a new bud appears are marked with purple color.
