1. General Information

All chemicals were purchased from commercial vendors and used without further purification, unless otherwise

noted. All non-aqueous reactions were carried out under a nitrogen/argon atmosphere in oven-dried glassware. Reaction

progress was monitored by TLC on pre-coated silica plates (Merck 60 F254 nm, 250 μm thickness) and spots were visualized by UV light or appropriate staining (e.g., ceric ammonium molybdate (CAM), basic KMnO4). Flash column

chromatography was carried out using silica gel (Merck 60 F254 nm 0.040-0.063 μm). All 1H NMR and 13C NMR spectra

were taken on a Bruker AFC 300 (300 MHz) or AMX500 (500 MHz) spectrometer. Chemical shifts were reported in

parts per million (ppm) relative to residual solvent peaks (CDCl3 = 7.26 ppm, DMSO-d6 = 2.50 ppm, CD3OD = 3.31 ppm,

Acetone-d6 = 2.05 ppm). 1H NMR coupling constants (J) are reported in Hertz (Hz) and multiplicity is indicated as

follows: s (singlet), d (doublet), t (triplet), q (quartet), m (multiplet), br s (broad singlet), br d (broad doublet), dd (doublet

of doublet), dt (doublet of triplet), dq (doublet of quartet), tq (triplet of quartet). Analytical HPLC and Mass spectra were

recorded on a Shimadzu LC-IT-TOF spectrometer or LC-ESI spectrometer equipped with an autosampler, using

reverse-phase Phenomenex Luna 5 μm C18 100 Å 50 × 3.0 mm columns. UV-vis absorption and fluorescence spectra

were measured by using a Shimadzu UV-vis spectrophotometer and a Perkin Elmer LS50 spectrofluorometer,

respectively. The two-photon excited fluorescence measurements were performed using a Spectra Physics femtosecond

Ti:sapphire oscillator (Tsunami) as the excitation source. The output laser pulses have a tunable center wavelength at 760

nm with pulse duration of 40 fs and a repetition rate of 76 MHz. The laser beam was focused onto the sample that was

contained in a cuvette with path length of 1 cm. The emission from the sample was collected at 90° angle by a pair of

lenses and an optical fiber that was connected to a monochromator (Acton, Spectra Pro 2300i) coupled with CCD system

(Princeton Instruments, Pixis 100B). A short pass filter with cut-off wavelength at 700 nm was placed before the

spectrometer to minimize the scattering from the pump beam. All optical measurements were performed at room

temperature. All 2D images were acquired on Leica TCS SP5X Confocal Microscope System equipped with Leica HCX

PL APO 63x/1.20 W CORR CS, 405 nm Diode laser, Argon ion laser, white laser (470 nm to 670 nm, with 1 nm

increments, with 8 channels AOTF for simultaneous control of 8 laser lines, each excitation wavelength provides 1.5

mV), and Ti-Sapphire laser (~4 W at 800 nm) which corresponded to approximately 1% (~40 mW at 800 nm) average

power in the focal plane. A PMT detector ranging from 420 nm to 700 nm for steady-state fluorescence was used with

Leica and images were processed with Leica Application Suite Advanced Fluorescence (LAS AF).

Human recombinant JNK1 (M33-10G-10) and its substrate ATF2 (A10-55G-20) were purchased from SignalChem.

JNK-IN-8 was a gift from Prof. Nathanael S. Gray (Harvard Medical School). Anisomycin (2222S), antibodies against

Phospho-JNK (9255S), total JNK (9252S) and Phospho-c-Jun (9261S) were obtained from Cell Signaling Technology.

Human JNK1 plasmid (transcript variant JNK1-b2 Gene ORF cDNA clone expression plasmid, C-GFPSpark tag;

HG10795-ACG) was purchased from Sino Biological Inc. FITC-conjugated Goat anti-rabbit IgG (H+L) secondary

antibody (A16097), Lipofectamine® 2000 Transfection Reagent (11668027) and Opti-MEM® (Reduced Serum Medium;

31985070) were bought from Thermo Fisher Scientfic. Cell lines (HeLa, HEK293T, SH-SY5Y) were purchased from

ATCC.

mL, 3.25 mmol) in anhydrous dioxane (110 mL) at room temperature. The reaction mixture was stirred at 120 oC for 24 h,

before being cooled to room temperature. Subsequently, concentrated ammonia (55 mL) and brine (220 mL) were added

and the resulting mixture was extracted with EtOAc (5 × 220 mL). The organic layers were dried over Na2SO4,

concentrated under reduced pressure and the residue was purified by flash chromatography (DCM/MeOH = 50/1) to give

reaction mixture was washed with CuSO4 (aq.) and extracted with EtOAc. The organic layers were dried over anhydrous

Na2SO4 and concentrated. The resulting crude product was directly used in the next step without further purification. 1H

C1 was synthesized according to published procedures.[7] A two-neck flame-dried 250 mL round bottomed flask

(RBF) was outfitted with a stir bar, gas inlet adapter and a rubber septum, then filled with nitrogen. The flask was

charged with rhodium tetraacetate (0.2210 g, 0.50 mmol) and trimethylsilyl acetylene (2.2450 g, 22 mmol) sequentially,

and while being stirred, the mixture was added ethyl diazoacetate (1.141 g, 10 mmol) at a rate of 0.5 mL/h via a syringe

pump. Upon completion of the addition, the resulting mixture was further stirred for 30 min before being concentrated in

vacuo and purified by flash chromatography (EtOAc/hexane = 1/30) to give 1.8400 g (92.8%) of the title compound as a

vacuo, the resulting yellow aqueous solution was acidified with HCl (1 M) to pH = 3. The organic layer was next

extracted with DCM three times, combined and dried over Na2SO4 before being concentrated in vacuo. Finally, the

mixture was purified by flash chromatography to give A2 (39.2 mg, 97.4%). 1H NMR (300 MHz, CDCl3) δ 6.97 (dd, J =

3. Experimental Methods

3.1. Photophysical properties of probes. All compounds were diluted in DMSO (if not specified) and the

measurements were performed at room temperature. UV-vis absorption and fluorescence spectra were measured at a

concentration of 10 μM in 1-cm standard quartz cells by using a Shimadzu UV-vis spectrophotometer and a Perkin Elmer

LS50 spectrofluorometer, respectively. The fluorescence quantum yield (Φ) was determined by using fluorescein aqueous

NaOH solution (pH = 13; Φ = 0.95) as the reference through Фs = Фr(ns2EsAr)/(nr

2ErAs), where the subscripts s and r refer

to the sample and reference compound. E is the integrated area under the emission spectrum. A is the absorbance of the

solution at the excitation wavelength and n is the refractive index of the solvent. The two-photon excited fluorescence

intensity was measured at 760 nm at 1 or 10 μM of the compound as indicated. The two-photon action cross section

(TPA cross section, δФ) was calculated with AAN as the reference (whose two-photon properties had previously been

reported[18]), by using the equation δsФs= δrФr(Ssφrcr)/(Srφscs). The intensity of the detected signals was denoted as S. φ is

the overall fluorescence collection efficiency of the experimental apparatus. The number density of the molecules in

solution was denoted as c. δr is the two-photon absorption cross section of the reference molecule.

3.2. IC50 values of probes.[19] Concentration-dependent experiments were performed to determine the in vitro

inhibition potency and the binding affinity of the probes towards the catalytic domain of JNK. The inhibition assay was

performed with Kinase-Glo® Plus Luminescent Kinase Assay (V3772, Promega) following the manufacture’s instructions. Recombinantly active JNK1 (M33-10G-10, SignalChem; 0.1 μg in 1 μL), 1 μL probe/wilde type inhibitor (JNK-IN-8), substrate (0.2 μg ATF2 diluted in 10 μL kinase buffer; A10-55G-20, SingalChem) and ATP (final

concentration: 10 μM; add 10 μL of 22 μM stock solution) were mixed in the kinase buffer (40 mM Tris, pH 7.5, 20 mM

MgCl2, 0.1 mg/mL BSA) at a total volume of 22 µL in a 1.5 mL Eppendorf tube. The incubation was allowed to continue

for 20 min at 37 °C with shaking (700 rpm) and the reaction was subsequently quenched by addition of an equal volume

(22 µL) of the Kinase-Glo reagent. After ~5 min of incubation, 35 μL/well of the reaction mixture was transfered to a

flat-bottom solid white 384-well plate in duplicate, then the luminescence readouts from the wells were measured using a

BioTek Synergy 4 plate reader. The IC50 values of the probes were calculated from the percentage activity vs. log

[concentration of probe] curves generated from GraphPad Prism software.

3.3. In vitro labeling of probes towards recombinant JNK1. For gel-based in vitro protein labeling experiments,

S1_13

procedures were based on previously published protocols with some modifications.[19b, 20] 50 ng of recombinant JNK1

(M33-10G-10, SingalChem) was diluted in 20 μL HEPES (25 mM HEPES, 2 mM MgCl2, 150 mM NaCl, pH = 7.5)

containing 0.01% triton. JNK1 was incubated with 1 μM of probe for 1 h at room temperature with gentle shaking (600

rpm), followed by CuAAC/click chemistry (a mixture of 200 μM CuSO4, 20 μM THPTA, 200 μM TCEP and 10 μM

TER-N3 for JP3, or 10 μM TER-Tz1 for JP2-TCO and JP2-CP) for 2 h at room temperature. Next, 4 μL 6 × loading dye

without DTT was added into the mixture and, without boiling, all samples were resolved on a 12% SDS-PAGE gel. For

competition experiments, JNK1 was pretreated with 10 μM of JNK-IN-8 for 1 h at room temperature with gentle shaking

(600 rpm) before addition of probes. For AfBPs (i.e., SP-1 and IM-1), the reaction mixture in Eppendorf tubes was UV

irradiated (365 nm for 10 min at 4 °C) before click chemistry. In-gel fluorescence scanning (FL) was used to visualize the

labeled protein bands followed by silver staining (SS).

3.4. Cellular activities and in situ proteome profiling in mammalian Cells. Human carcinoma epithelial carcinoma

(HeLa), human embryonic kidney (HEK293T) and neuroblastoma (SH-SY5Y) cell lines were cultured in Dulbecco’s Modified Eagle's Medium (DMEM) supplemented with 10% fetal bovine serum (FBS), 100.0 mg/L streptomycin and

100 IU/mL penicillin in a humidified atmosphere of 5% CO2 at 37 oC. For Western blotting (WB), equal amount of

lysates diluted in SDS loading buffer was separated by 12% SDS-PAGE before being transferred onto a Polyvinylidene

Fluoride Transfer Membrane (BioTraceTM PVDF). The PVDF membrane was then blocked with 3% BSA in 1× TBS

containing 0.1% Tween-20 (TBST) for 1 h at room temperature. Then the membrane was probed with a suitable primary

antibody (1:1000) and shaken at room temperature for 1 h or at 4 °C overnight. HRP-conjugated secondary antibody

(1:5000) was incubated at room temperature for 1 h. The antibody-reactive bands were visualized by chemiluminescent

detection (SuperSignal™ West Dura Chemiluminescent Substrate from Thermo Scientific™).

The cell-based kinase assays for c-Jun phosphorylation were carried out by using HeLa cells.[6] The phosphorylation

level of c-Jun was determined by Western blotting (WB) using the anti-phospho-c-Jun antibody (anti-p-c-Jun). Cells

were grown in 12-well plates to ~70% confluency. 0.5 mL of fresh DMEM (without FBS) was applied to the cells before

addition of compounds for 2 h. Then cells were treated with compounds at indicated concentrations for 3 h (compounds

were applied from DMSO stocks whereby DMSO never exceeded 1% in the final solution) followed by 1 h of

stimulation with 2 μM of anisomycin. The cells were collected by scraping and washed with PBS before being lysed with

100 μL 1 × SDS loading buffer. The sample was heated at 95 oC for 10 min and loaded at 10 μL/lane for WB analysis using anti-phospho-c-Jun antibody.

Transfection of JNK1-GFP plasmids was carried out according to the manufacturer’s guidelines (Lipofectamine®

2000 Transfection Reagent). One day before transfection, HeLa cells were seeded in a 24-well plate (for in situ

labeling)/4-well imaging dish (Greiner Bio-One, #627870; for cellular imaging) with 0.5 mL/well of DMEM (containing

10% FBS but without antibiotics) and left for 24 h until they reached ~80% confluency. The next day before transfection,

the old medium was replaced with 0.4 mL/well fresh DMEM (containing 10% FBS but without antibiotics). To prepare

plasmid-Lipofectamine® 2000 complexes: 1) dilute plasmids (0.8 µg/well for in situ labeling; 0.4 µg/well for cellular

imaging) in 50 µL of Opti-MEM® (Reduced Serum Medium) and mix gently; 2) dilute the appropriate amount of

Lipofectamine™ 2000 (2 µL/well for in situ labeling; 1 µL/well for cellular imaging) in 50 µL of Opti-MEM® and mix

gently before incubation for 5 min at room temperature. Afterwards, the diluted Lipofectamine® 2000 and diluted

plasmids were combined and incubated for 20 min at room temperature. The final 100 µL of plasmid-Lipofectamine®

2000 complexes were added to each well containing cells and medium. With gentle rocking of the plate, cells were

incubated at 37 °C in a CO2 incubator for ~20 h before further experiments.

For in situ proteome labeling, two methods were used: (1) for JNK1-GFP-transfected HeLa cells, transfected cells

(as described above in 24-well plates) were pretreated with/without WT (JNK-IN-8, 10 μM) in 250 μL of FBS-free

DMEM for 1 h before addition of probes at indicated concentrations for another 1 h. Cells were washed with PBS gently

before being detached by addition of 50 μL lysis buffer (HEPES buffer containing 0.1% triton and supplemented with

S1_14

protease inhibitor cocktail (04693159001 ROCHE)) and scraping. After being homogenized by sonication, the

supernatant was obtained (13000 rpm × 20 min at 4 °C). For AfBPs, cells were UV-irradiated (365 nm) for 15 min at

4 °C in PBS after probe addition. A freshly premixed click chemistry reaction cocktail (1 mM CuSO4, 0.1 mM THPTA, 1

mM TCEP and 25 μM TER-N3 for JP3/SP-1) or TER-Tz1 (10 μM for JP2-TCO/JP2-CP) was added to the supernatant.

The reaction was further incubated for 2 h with gentle mixing at room temperature, before being terminated by addition

of five-fold pre-chilled acetone (2 h at -20 °C). Precipitated proteins were subsequently collected by centrifugation

(13000 rpm × 15 min at 4 °C). The supernatant was discarded and the pellet was washed with MeOH/CHCl3/H2O (=

4/1/4). The residue was redissolved in 10 μL 2 × loading buffer and heated for 10 min at 95 °C. All proteins were loaded

and separated by 12% SDS-PAGE gel and then visualized by in-gel fluorescence scanning. WB against JNK and loading

control GAPDH were always carried out to indicate the transfection efficiency and total protein amount; (2) for in situ

labeling against endogenous JNKs, HEK293T, HeLa or SH-SY5Y cells were grown to ~80% confluency in 6-well (for

JP2-TCO) or 12-well (for JP3) plates. The medium was removed, and cells were washed with FBS-free DMEM and

incubated in 1 mL of FBS-free DMEM. Cells were then pretreated with/without WT (JNK-IN-8, 10 μM) for 1 h before addition of probes (JP2-TCO/JP3 at various concentrations) for another 1 h. Subsequently, cells were induced with or

without 2 μM of anisomycin for another 0.5 h. The cells were detached and washed gently with PBS twice to remove

excessive probes. The cells were resuspended in 200 μL (for 6-well plates) or 100 μL (for 12-well plates) of lysis buffer

(HEPES buffer containing 0.1% triton and supplemented with protease inhibitor cocktail (04693159001 ROCHE)), then

homogenized by sonication. The supernatant was clicked and treated as described in (1), followed by in-gel fluorescence

scanning. Coomassie Brilliant Blue (CBB) staining was always carried out afterwards.

3.5. Cellular imaging. For model studies with homopropargylglycine (HPG)[21] and AAN-N3, in-solution click

reactions were first carried out to determine the optimal condition suitable for cellular imaging with AAN-N3. The

following three click conditions were compared in PBS buffer or HeLa lysates (2 mg/mL) with AAN-N3 (0.1 mM) and

propargyl alcohol (0.2 mM), and the reactions were monitored by HPLC: Cond 1. 50 μM CuSO4, 300 μM THPTA, 2.5 mM NaASc; Cond 2. 1 mM CuSO4, 0.1 mM THPTA, 2 mM NaASC; Cond 3. 1 mM CuSO4, 300 μM THPTA, 10 mM NaASc. Each reaction was prepared by first adding CuSO4 (5 or 50 mM stock solution in H2O) and THPTA (5 mM stock

solution in H2O) to PBS. Next, freshly prepared NaASc (100 mM in PBS) was added. Finally, 5 mM of AAN-N3 in

DMSO and 8 mM of propargyl alcohol were added to a final volume of 200 μL. For click reaction in HeLa lysates, the

lysates (2 mg/mL) was added and mixed properly before addition of the alkyne. None of the above conditions however

provided strong signal-to-background contrast in cellular imaging with HPG-treated cells (data not shown).

For cellular imaging with JP3 in HeLa cells transfected with JNK1-GFP, transfection was first carried out as above

described. Upon washing with FBS-free DMEM and re-introduction of FBS-free DMEM (0.5 mL/well), cells were

treated with or without WT (JNK-IN-8, 20 μM) for 1 h before introduction of JP3 (5 μM) for an additional 1 h. For

comparison with AfBPs, probe-treated cells were UV-irradiated (365 nm) for 15 min at 4 °C in PBS, washed (with PBS)

and fixed with 3.7% formaldehyde in PBS at room temperature for 15 min. The formaldehyde solution was removed and

the cells were washed twice with PBS. The cells were then permeabilized with 300 μL 0.1% Triton-X-containing PBS for

10 min at room temperature. The Triton-X was removed and the cells were washed twice with PBS, then covered with

200 μL of click solution. The click solution comprised of 1 mM CuSO4, 100 μM THPTA, 1 mM TCEP, and 25 μM of TER-N3 (1 mM CuSO4 from 1 M stock solution in H2O was mixed with 0.1 mM THPTA from 0.1 M stock solution in

H2O and vortexed. 1 mM TCEP from 0.5 M stock solution in H2O was then added and vortexed. Finally, 25 μM TER-N3

(from 10 mM stock solution in DMSO) was added) and the solution was diluted with PBS before being applied to cells.

After 2-h incubation at room temperature in dark with gentle shaking, cells were washed with PBS at least three times

and 0.1% Triton-X in PBS for once, followed by incubation with anti-JNK (1:100, CST #9252S) at 4 °C overnight. Upon

washing with PBS for three times (10 min each) and incubation with FITC-conjugated Goat anti-rabbit IgG (H+L)

secondary antibody (1:200, ab6717) for 2 h at room temperature, cells were then washed with PBS for three times (10

S1_15

min each), 0.1% Triton-X-containing PBS for 10 min, PBS once again, and imaged.

For no-wash direct imaging with live mammalian cells, the followings were done: (1) Model studies by using a

TCO-containing puromycin probe (5T):[2] HeLa cells were grown to ~70% confluency in 4-well imaging dishes before

being treated with 10 μM of 5T in 0.5 mL DMEM for 2 h. Afterwards, cells were washed with FBS-free DMEM for

three times before reintroduction of 0.5 mL FBS-free DMEM containing 1 μM of QT1 or QT2 for another 1 h. Live-cell

imaging was directly carried out without washing; (2) Using JP2-TCO in JNK1-GFP-transfected HeLa cells. HeLa cells

were transfected with JNK1-GFP as described above before incubation with the probes. Upon washing with FBS-free

DMEM and re-introduction of FBS-free DMEM (0.5 mL/well), cells were treated with or without WT (JNK-IN-8, 4

times of probe) for 1 h before introduction of JP2-TCO (0.5 or 5 μM as indicated) for an additional 1 h. The cells were

then washed twice with FBS-free DMEM. 10 μM of QT1/QT2 from 1 mM stock solution was added to cells containing

0.5 mL fresh FBS-free DMEM and reacted for 1 h at 37 oC. Live-cell imaging was carried out directly without washing.

As a control, TMR-Tz (1 μM) was used instead of QT1/QT2 to check the cellular distribution of JP2-TCO. To remove

the background completely, after 1-h incubation, cells were washed with PBS for twice and treated with cold MeOH at

-20 oC for 5 min to fix and permeabilize the cells. Immunofluorescence (IF) imaging was carried out as described above

by using FITC-Rb for colocalization study of the fixed cells.

Microscopic light source and filters used for imaging include: (1) GFP/FITC, ex = 488 nm, em = 500-550 nm; (2)

TER-N3/TMR-Tz, ex = 557 nm, em = 570-650 nm; (3) QT1/QT2, ex = 405 nm and em = 420-550 nm for one-photon

channel, and ex = 760 nm, em = 450-550 nm for two-photon channel.

3.6. In situ pull-down (PD), Western blotting (WB) and LC-MS/MS experiments. To validate potential cellular targets

of the probes, pull-down (PD) experiments were carried out, followed by Western blotting. The general PD/WB

procedure was based on previously reported protocols,[19b, 20] with the following optimizations. Briefly, cells were grown

to ~80% confluency in 10-cm cell culture dishes containing 10 mL of fresh DMEM (without FBS). The probe (0.1 or 0.5

µM as indicated), with or without pretreatment of WT (10x, 1-h pre-incubation) for competition, was directly added to

live cells, followed by incubation at 37 ºC/5% CO2 for 1 h. DMSO should never exceed 1% in the final solution. 2 μM of anisomycin was used to activate JNKs where indicated. Cells treated with DMSO instead of probes served as a negative

control. The medium was subsequently removed by aspiration, and cells were washed gently with PBS twice to remove

excessive probe. The cells were then scraped and lysed using 2 mL of lysis buffer (HEPES buffer containing 0.1% triton

and supplemented with 0.1 mM of PMSF), followed by homogenization by sonication. The supernatant was collected by

centrifugation (13000 rpm × 20 min at 4 °C) and subjected to click reaction with 25 μM of Biotin-N3 (1 mM CuSO4, 0.1

mM THPTA, 1 mM TCEP, room temperature) for alkyne-containing probes, or 25 μM of Biotin-Tz2 (37 oC) for

TCO-/CP-containing probes for 2 h. After acetone precipitation (10 mL, -20 °C, overnight) and 5 mL-methanol wash (3x,

-80 °C, 1 h/each time), the air-dried pellets were resolubilized in 0.8 mL of 5% SDS-containing TBS with brief

sonication. 50 μL of the solution was kept as “before PD sample (BP)”. Additional 3 mL TBS was added to the remaining

solution, making the final concentration of SDS as 1%. Upon thorough mixing, these resuspended samples were then

centrifuged at 13000 rpm for 20 min. The collected supernatant was incubated with NeutrAvidin™ Agarose Resins (#

29204, Thermo Scientific; 100 µL/mg protein) for 5 h at room temperature with gentle shaking. After centrifugation

(1000 rpm, 1 min), the supernatant was removed and the beads were washed with 1% SDS in TBS twice, 5% SDS in

TBS once, 1% SDS in TBS twice and TBS without SDS once. After washing, the beads were boiled in 200 μL of 2 × SDS loading buffer for 30 min and then concentrated to 100 μL. Control samples treated with DMSO instead of probes were carried out concurrently. Results were analyzed by WB analysis.

For standard LC-MS/MS, the PD samples were first separated by 12% SDS-PAGE gel and subjected to CBB

staining. The avidin band (~15 kDa) was discarded and the remaining gel was excised and subjected to tryptic in-gel

digestion. Tryptic peptides were extracted from the gel and analyzed as previous described.[2, 13, 19b, 20, 22] All peptide

samples were dried in a speedvac and reconstituted with 20 L of 0.1% TFA/H2O. The peptides were separated and

S1_16

analyzed on a nanoAcquity (Waters) LC system coupled with Q-Exactive Orbitrap mass spectrometer (Thermo Scientific

Inc.). Samples were loaded onto a fused silica desalting column packed with 2 cm C18 reverse phase resin (Phenomenex

Inc.), and peptides were separated on a reverse phase column (100 μm fused silica packed with 25 cm C18 resin). Peptide

separation condition was a gradient 5-50% Buffer B in Buffer A (Buffer A: water, 0.1 % formic acid; Buffer B:

acetonitrile, 0.1% formic acid), and the flow rate through the column was set to 250 nL/min, and spray voltage was set to

1.6 kV. One full MS scan (350-1800 MW) was followed by 10 data dependent scans of most intense ions with dynamic

exclusion enabled. The generated tandem MS data was searched using IPI Human database (version: 3.87) using

Proteome Discoverer software (v.1.4.0.288). A maximum of three missed cleavages were allowed and fully tryptic

peptides were considered with dynamic modification of acetyl at N-terminal. The maximal mass tolerance in MS mode

was set to 10 ppm, and fragment MS/MS tolerance was set to 0.8 Da for HCD data. The maximum peptide and site false

discovery rates were specified as 0.01 using Percolator. The obtained peptide/protein list for each fraction was exported

to Microsoft Excel or processed using an in-house script for further analysis.

With standard LC-MS/MS data, DMSO-treated cells served as controls to distinguish JNK probe-enriched proteins

from non-specific proteins where putative hits from JP3/JP2-TCO/JP2-CP labeled samples were defined as those

proteins exclusively present in probe-treated cells but not in the DMSO control.[23]

(A) No-wash imaging of newly synthesized proteins labeled by 5T (10 μM, 2 h; structure shown on the right) in live HeLa cells with QT1/QT2 (1 μM, 1 h) under one- (ex = 405 nm, panels 1/4/7/10) or two-photon (ex = 760 nm, panels 2/5/8/11)

excitation, with em = 450-550 nm. (B-E) Cellular imaging of JNK1-GFP-transfected HeLa cells by using JP3/JP2-TCO. (B-C) Cellular localization of JP3/JP2-TCO upon

click reaction with TER-N3/TMR-Tz. Where applicable, 4-fold WT (JNK-IN-8) was used as a competitor to identify the specificity of fluorescent signals. Cells were fixed

and permeabilized, followed by immunofluorescence (FITC-labeled antibody) against JNK (the fluorescence from the expressed GFP was quenched after fixation). (D-E)

Live-cell imaging of JNK1-GFP-transfected HeLa cells with JP2-TCO (5 μM, 1 h) with or without WT (JNK-IN-8, 20 μM, 1-h pre-treatment). After a single wash to remove

unreacted probes, the cells were clicked with QT1/QT2 (10 μM, 1 h) followed by direct live-cell imaging. λex = 488 nm, λem = 500-550 nm for JNK1-GFP; λex = 557 nm, λem

= 570-650 nm for TER/TMR; λex = 405 nm, λem = 450-550 nm for QT1 and QT2. (F) Cellular imaging of AfBPs in JNK1-GFP-transfected HeLa cells in comparison with

JP3. Cellular localization of JP3/AfBPs was visualized upon click reaction with TER-N3. Where indicated, 4-fold WT (JNK-IN-8) was used as a competitor to identify the

specificity of fluorescent signals. JNK1-GFP transfected HeLa cells were treated with 5 μM of probes for 1 h with or without pre-treatment of WT (JNK-IN-8, 20 μM, 1 h). After a single wash to remove unreacted probes, the cells were UV irradiated (15 min on ice) in PBS and fixed prior to click chemistry. Immunofluorescence (FITC-labeled

antibody) against JNK was also conducted before imaging. λex = 488 nm, λem = 500-550 nm for JNK1-GFP; λex = 557 nm, λem = 570-650 nm for TER. Parts of the figure was

reproduced in Fig. 2 in the maintext. Scale bar = 20 μm.

Protocol for MS analysis

Cell experiment and data analysis

LC-MS analysis was performed on a nanoAcquity (Waters, inc) configured with Q-exactive Orbitrap mass spectrometer (ThermoScientific Inc.). Digests were loaded onto a fused silica desalting column packed with 2 cm C18 reverse phase resin (Phenomenex Inc.), and

peptides were eluted on a reverse phase column (100 μm fused silica packed with 25 cm C18 resin) using a gradient 5-50% Buffer B in Buffer A (Buffer A: water, 0.1 % formic acid; Buffer B: acetonitrile, 0.1% formic acid). The flow rate through the column was set to 250

nl min-1and spray voltage was set to 1.6 kV. One full MS scan (350 – 1800 MW) was followed by 10 data dependent scans of most intense ions with dynamic exclusion enabled. The generated tandem MS data was searched using IPI Human database (version: 3.87)

using Proteome Discoverer software (v.1.4.0.288). A maximum of three missed cleavages were allowed and fully tryptic peptides were considered with dynamic modification of acetyl at N-terminal. The maximal mass tolerance in MS mode was set to 10 ppm, and

fragment MS/MS tolerance was set to 0.8 Da for HCD data. The maximum peptide and site false discovery rates were specified as 0.01 using Percolator. Quantitative SILAC ratio was calculated using Proteome Discoverer "Precursor Ions Quantifier" modules. Lastly, gene

ontology analysis was performed using Gene Ontology Consortium (http://geneontology.org).

HeLa cells grown in 10-cm dishes were incubated with 1 μM of JP3/JP2-TCO/JP2-CP for 1 h before induction of 2 μM of anisomycin for additional 0.5 h to activate JNKs. Cells treated with DMSO were carried out concurrently as controls. Putative Hits of the probe are

targets that were enriched and detected in probe-treated sample but not in the DMSO control. (JNK1/2/3 (also known as Mitogen-activated protein kinase 8/9/10) were highlighted in red).
