(A) Immunoblot for the phosphorylation of mTOR effector proteins during different conditions. Torin was used as a positive control for mTOR inhibition. Tubulin was used as a loading control. (B) Quantification of the fold change p-S6K/S6K from immunoblot data in (A). Data represents the mean of n=4 replicates. one-way ANOVA using Tukey’s multiple comparison, **P= 0.0011 (Untreated VS Torin), ns P = 0.9809 (Untreated VS YM201636), ns P = 0.99997 (Untreated VS 15 min recovery), ns P = 0.6835 (Untreated VS 30 min recovery), ns P = 0.99997 (Untreated VS 60 min recovery).

Data represents the mean of n=4 replicates. one-way ANOVA using Tukey’s multiple comparison, ***P = 0.000038 (Untreated VS Torin), ns P = 0.9370 (Untreated VS YM201636), ns P = 0.99999 (Untreated VS 15 min recovery), ns P = 0.999993 (Untreated VS 30 min recovery), ns P = 0.9605 (Untreated VS 60 min recovery). (D) Live-cell imaging of cells expressing LAMP1-GFP (green) stained with LysoTracker deep red (magenta) to assess the lysosomal reformation in presence of 250 nM torin. Images were acquired after 2 h YM201636 treatment and 30 min washout. (G) Average area of LAMP1-positive structures was quantified. Each dot represents the average area of per 100 µm 2 ROI; plot shows mean area from a total of 90 ROI from 30 cells across n=3 biological replicates; Unpaired t-test; ns, P = 0.1980 (DMSO vs Torin). (F) Live-cell imaging of cells expressing LAMP1-mScarlet (magenta) together with DNM2-GFP or the GTPase mutant DNM2 (K44A)-GFP to assess DNM2 function in tubule fission. Images were acquired after 2 h YM201636 treatment and 30 min. (G) Quantification of LAMP1-positive tubule length (magenta) in cells overexpressing wild-type or mutant DNM2. Each dot represents the length of a single tubule; plot shows mean length from a total of 150 tubules across n=3 biological replicates; Unpaired t-test; ns P = 0.0564 (DNM2 WT vs. DNM2 K44A). (H) Schematic representation of the proximity labelling assay using LAMP1 fused to the biotin ligase TurboID. (I) Volcano plot comparing the biotinylated proxisome of LAMP1-TiD in cells treated with YM201636 for 2 h plus 30 min recovery versus untreated controls. Proteins significantly enriched during tubulation and fission are highlighted on the right side of the plot. Data from n=3 biological replicates. (J) Major categories of candidate proteins enriched during tubulation and fission.
