It was found that the 5A fragment in which five Ser/Thr residues were substituted with Ala (S144A/T145A/S185A/T186A/S187A) fully prevented phosphorylation (Fig. 5B), confirming that Aurora B primarily phosphorylates five Ser/Thr residues in the basic region of MgcRacGAP. | the strong phosphorylation of the basic region of MgcRacGAP by Aurora B kinase was demonstrated, and this phosphorylation prevents the inhibition of MgcRacGAP GAP activity by PRC1 |

We report here that (i) mgcracgap is phosphorylated by aurora b and cdk1, (ii) pp2a dephosphorylates aurora b and cdk1 phosphorylated sites and (iii) inhibition of pp2a abrogates mgcracgap/ect2 interaction. Therefore, pp2a may regulate cytokinesis by dephosphorylating mgcracgap and its interacting partners. |

We therefore developed a screening-compatible live-cell imaging assay, using FRET-based biosensors for the prototype GTPases RHOA, RAC1 and CDC4215,19,20 (Extended Data Fig. 2 and Supplementary Note 1)|We found catalytic activities for 45/75 RhoGEFs and 48/63 RhoGAPs| Our data thus not only reveal extensive promiscuity among regulators, but also that the inactivating RhoGAPs are less selective than the activating RhoGEFs (p-value=0.02)(Supplementary Table 2). |
