Figure 4The extreme C-terminal sequence of indicated secretory and mitochondrial proteins. The diGly, R__G and R_G_ motifs are labeled red. Stability analysis of indicated proteins in cells treated with shRNAs against various BC-box proteins. Since GFP was tagged at the protein N-terminus and signal peptide and MTSs need to be exposed to be functional, all tested proteins were mislocalized. Protein stability analyses of wild-type (WT) and mutant proteins lacking their extreme terminal Gly (∆G) or having it masked by adding Leu (+L) in cells with or without BC-box protein knockdown (C) or overexpression (D). Western blot analysis of Flag-tagged proteins in cells with or without KLHDC3 or APPBP2 expression. The N-terminal Flag abolished protein targeting. GAPDH serves as a loading control. Fractionation and Western blot analysis of wild-type and Flag-tagged PDP2 (top), and wild-type and MTS-deleted (∆MTS) MRPL28 (bottom). Flag-PDP2 and ∆MTS MRPL28 were mislocalized. W, C, and M denote whole cell lysates, cytosol fraction and mitochondrial fraction, respectively. Tubulin and VDAC serve as fractionation quality controls. Protein abundance analysis of HA-tagged wild-type or mutant secretory proteins with their signal peptide deleted (∆SP) in cells with or without KLHDC3 or APPBP2 expression. The HA epitope was inserted immediately after the signal peptide (SP), which had no impact on protein secretion.

Atg1 travels with autophagosomes to the vacuole during starvation.Figure 5(A) atg1Δ cells containing either wild‐type Atg1 or the kinase‐dead Atg1‐T226A mutant tagged with GFP were grown to mid log phase followed by starvation for 24 h in SD‐N. Samples were taken at indicated time points and GFP cleavage was analysed by western blotting. Processing of endogenous Ape1 under starvation conditions monitors the autophagic flux.

(C) atg1Δpep4Δ cells containing YFP‐tagged wild‐type Atg1 or the Atg1‐VE mutant were grown to log phase and starved in SD‐N. Cells were monitored by time‐lapse microscopy and the vacuolar accumulation of Atg1 was quantified as described in 'Materials and methods'. Data are plotted as the mean±s.e.m. from at least 90 quantified cells. Additional images are shown in Supplementary Figure S3H. Bar=5 μm.

E Experimental set-up: Age-synchronized 4-day-old animals were subjected to heat stress for 3 h at 33°C (+HS) then returned to 20°C or left at 20°C (-HS), respectively. Arrows indicate imaging time points. The -HS controls were imaged at the same time point as the +HS animals after 24h at 20°C. Maximum intensity projections of fluorescent microscopy z-stacks of animals expressing the indicated transgenes. Scale bar: 20 µm. The impaired clearance of HS-induced FLUCSM::GFP foci in the hsp-110 hairpin expressing cells is rescued by co-expression of WT but not by the HSP-70 binding deficient SSE1N575Y E575A mutant.

(D) The amplitude of oscillations are significantly higher in kcHIEs/bHIEs compared to HIOs. Bmal1-luc traces in B were generated by plotting the standard deviation of n≥3 biological replicates.

eIF4A regulates TORC1 via TSC2.Figure 5(a) Knockdown of eIF4A and TSC2 do not elevate TORC1 activity in an additive manner, indicating they act in the same, and not parallel pathways. Whereas knockdown of eIF4A increases TORC1 activity in control Kc167 cells (lanes 1-2 and 5-6), eIF4A knockdown cannot further increase TORC1 activity in TSC2 knockdown cells (lanes 3-4 and 7-8). Error bars: std dev. n=3 biological replicates. (b) Activation of TSC2 with the p90RSK inhibitor BI-D1870 rescues the elevated TORC1 activity caused by eIF4A knockdown in Kc167 cells, consistent with TSC2 acting downstream of eIF4A. BI-D1870 leads to inhibition of TORC1 (lanes 1-4) in a TSC2-dependent manner (see also Appendix Figure S5A). Representative of two biological replicates. (c) FLAG-eIF4A and TSC2-V5 co-immunoprecipitate in Kc167 cells in the absence of chemical cross-linker. Cells were transfected with FLAG-eIF4A and TSC2-V5 expression vectors and treated with media containing or lacking amino acids for indicated timepoints prior to lysis and anti-FLAG immunoprecipitation. The experiment was performed in absence of the chemical cross-linker DSP. Representative of 3 biological replicates. (d) Expression of TSC2-insensitive (S15H or Q63L), but not wild-type (WT) Rheb causes TORC1 activity to remain high upon amino acid removal. Kc167 cells were transfected to express either wild-type or mutant Rheb and then incubated with Schneider's medium either containing or lacking amino acids for 30 minutes. Elevated TORC1 activity can be observed either by looking at phosphorylation of endogenous S6K, or phosphorylation of an HA-tagged S6K that was co-transfected with the Rheb constructs to assay specifically the transfected cells. Representative of two biological replicates.

a, Cultured TRPML1-/- (ML1-/-) skin fibroblasts showed less de-quenching of the iron-sensitive fluorescence than ML1+/- cells did.figf4a, Cultured TRPML1-/- (ML1-/-) skin fibroblasts showed less de-quenching of the iron-sensitive fluorescence than ML1+/- cells did. De-quenching was achieved by preloading the fibroblasts with an iron-sensitive dye, Phen Green SK (PG SK), and then adding the membrane-permeable transition metal chelator, 2,2′-bipyridyl (BPD). 2,2′-BPD is predicted to chelate free cellular iron (also referred to as chelatable or labile iron), which subsequently increases PG SK fluorescence. The original magnification used was ×200 b, The average 2,2′-BPD induced normalized change of fluorescence (Dgr;F/F0) for ML4 cells (ML1-/-; n = 6 experiments) is significantly (asterisk, P < 0.01) lower than for the parental ML1+/- cells. Fibroblast cells (n = 10-20) were analysed for each individual experiment. 4,4′-BPD, a 2,2′-BPD analogue that cannot bind Fe2+, did not induce any significant restoration of PG SK fluorescence. Error bars, s.e.m. c, An ML1-/- skin fibroblast cell showed autofluorescence in LAMP1-positive compartments. Autofluorescence (green) was detected within a range of excitation wavelengths (shown with excitation at 480 nm). No significant autofluorescence was observed for a ML1+/+ cell. Lysosomes were stained with a LAMP1 antibody (red). Differential interference contrast (DIC) images are shown for comparison.
