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). |

Here, we used cell biology, biochemistry, and genetic approaches to show that PTEN suppresses cell movement by blocking PREX2 GEF–catalyzed activation of the GTPase RAC1. PTEN binds PREX2 and directly inhibits GEF activity. |

Here, we report that P-REX2 interacts with PTEN via two interfaces. In summary, P-REX2 docks to the PDZ-BD of PTEN through its C-terminal domain, reads the phosphorylation state of the PTEN tail via the DH domain, and inhibits PTEN activity by unleashing the PH domain |
