Figure Lengend Snippet: (A) Schematic of full length MAPKAP1 isoform 1 wild-type (WT) and the MAPKAP1 deletion (Del) proteins with domains highlighted. CRIM, Conserved Region In The Middle. RBD, Ras Binding Domain. PH, Pleckstrin Homology. (B) Microscale thermophoresis of labeled FHH:MAPKAP1RBD (16.8nM) with a titration series of GDP or GTPγs-loaded Ras. The binding curve is positive as the MST signal of the complex is higher than MAPKAP1RBD alone. MST-on time of 5s, n = 3 independent replicates. (C) BioID-western blot streptavidin pulldowns and input levels for birA* control, NRASWT, NRASQ61K and NRASQ61K with FHH:eGFP, MAPKAP1WT:FHH or MAPKAP1Del:FHH expression in CHL-1 cells. PI3K p110α subunit, Raf-1, and HA protein pulldown are controls. Pulldown normalized signal relative to control birA*:NRASQ61K shown below. (D) Quantification of mTOR and Rictor protein levels in the streptavidin pulldowns normalized to HA pulldown. All values and statistical tests relative to birA*:NRASQ61K, n=6 (Welch’s two-sided t-test). (E) PLA with endogenous Pan-Ras and mTOR or Rictor in MT NRAS MM485 melanoma cells. Scale bar, 20 μm. (F) PLA quantification in (E). n=3 independent experiments, 6-8 fields analyzed per condition per experiment (unpaired two-sided t-test). EV, empty vector. (G) Quantification of LocaTOR2 experiments with FHH:eGFP, MAPKAP1WT:FHH or MAPKAP1Del:FHH expression. All values relative to average of FHH:eGFP and MAPKAP1WT:FHH fold induction; n=3 (unpaired two-sided t-test). (H) Quantification of FHH:eGFP, MAPKAP1WT:FHH and MAPKAP1Del:FHH expression relative to MAPKAP1WT:FHH for all experiments graphed in (G). **p< 0.01, ***p< 0.001, ****p< 0.0001, and ns= not significant; all bar graphed data mean ± SEM. MST data are mean ± SD. See also Figure S6 and Table S4.
