pmid sentence
In this study we report that aurora b-mediated phosphorylation of myogef at thr-544 creates a docking site for plk1, leading to the localization and activation of myogef at the central spindle.

pmid sentence
We reported previously that a guanine nucleotide exchange factor, myogef, localizes to the central spindle, activates rhoa, and is required for cytokinesis. In this study, we have found that plk1 (polo-like kinase 1) can phosphorylate myogef, thereby recruiting myogef to the central spindle as well as enhancing myogef activity toward rhoa. The in vitro kinase assay shows that plk1 can phosphorylate myogef on threonine 574.

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).
