A novel cross-talk in diacylglycerol signaling: the rac-gap beta2-chimaerin is negatively regulated by protein kinase cdelta-mediated phosphorylation. phosphorylation of beta2-chimaerin on ser(169) located in the sh2-c1 domain linker region via protein kinase cdelta, which retained beta2-chimaerin in the cytosol and prevented its c1 domain-mediated translocation to membranes |

We now demonstrate Lck-dependent phosphorylation of beta2-chimaerin in response to TCR triggering. We identify Tyr-153 as the Lck-dependent phosphorylation residue and show that its phosphorylation negatively regulates membrane stabilization of beta2-chimaerin, decreasing its GAP activity to Rac. |

Here we report that beta2-chimaerin is tyrosine-phosphorylated by src-family kinases (sfks) upon cell stimulation with epidermal growth factor (egf). Mutational analysis identified tyr-21 in the n-terminal regulatory region as a major phosphorylation site. these results suggest tyr-21 phosphorylation as a novel, sfk-dependent mechanism that negatively regulates beta2-chimaerin rac-gap activity. |

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). |
