ARAP1 associated with PTK6 in an EGF/EGF receptor (EGFR)-dependent manner. In addition, the SH2 domain of PTK6, particularly the Arg(105) residue that contacts the phosphate group of the tyrosine residue, was essential for the association. Moreover, PTK6 phosphorylated residue Tyr(231) in the N-terminal domain of ARAP1. Expression of ARAP1, but not of the Y231F mutant, inhibited the down-regulation of EGFR in HEK293 cells expressing PTK6. These results demonstrate that PTK6 enhances EGFR signaling by inhibition of EGFR down-regulation through phosphorylation of ARAP1 in breast cancer cells. |

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). |
