EXPERIMENTAL MODEL AND SUBJECT DETAILS
The human kinase library plasmid kit, containing open reading frames (ORFs) in Gateway Entry vectors, was provided by William Hahn and David Root (Johannessen et al., 2010; Yang et al., 2011) via Addgene (Kit # 1000000014). The human phosphatase library was obtained from Dharmacon (OHS4941, ORFeome Human Entry Collection Phosphatase). Destination vectors, including pDEST pcDNA5 FRT TO-eGFP and pDEST 30 Triple Flag pcDNA5 FRT TO, were kindly provided by Dr. Anne-Claude Gingras at Mount Sinai Hospital, Toronto, Canada (Couzens et al., 2013). Expression vectors encoding the FLAG- or GFP-tagged fusion proteins were generated via Gateway Cloning and sequenced before transfection. Vectors for kinase-dead mutants, including pFLAG-CMV-hErk1 (K71R) (Addgene plasmid # 49329), pCIG AKT3 (K177M) (Addgene plasmid # 73051), pMCL-HA-MAPKK1-8E (K97M) (Addg-ene plasmid # 40811), IRES-GFP-AXL-KD (K567R) (Addgene plasmid # 65498), and FLAG.PKCepsilon.K/W (K437W) (Addgene plasmid # 10796) were gifts from Melanie Cobb, Joseph Gleeson, Natalie Ahn, Aaron Meyer, and Alex Toker, respectively (Baek et al., 2015; Cenni et al., 2002; Meyer et al., 2015; O’Neil et al., 1990).
HEK293T cell transfection and stimulation
HEK293T cells were seeded at the density of 0.7 million per well in 6-well plates. After 24 h, cells were transfected with 2 mg plasmid and 4 mL of jetPRIME (PolyPlus) per well with the standard protocol provided by the manufacturer. For kinase and phosphatase dou-ble transfection experiments, cells were transfected with plasmids encoding GFP-tagged kinases and FLAG-tagged phosphatases 16 h and 24 h after seeding, respectively. Half the amounts of plasmid and jetPRIME were used in each round for co-overexpression experiments. At 18 h after transfection, EGF (Peprotech) was added to a final concentration of 100 ng/ml. At 20 min before a given EGF stimulation time point, 5-iodo-deoxycytidine (IdU) was added to the medium at the final concentration of 10 mM. At 2 min before a given EGF stimulation time point, medium was replaced by 1X TrypLE to induce cell detachment. At the time point, paraformaldehyde (PFA, from Electron Microscopy Sciences) was added to the cell suspension to a final percentage of 1.6%, and cells were incubated at room temperature for 10 min. If EGF stimulation was not necessary in the experiment, cells were directly harvested and crosslinked with PFA.
